Opportunities & Risks Of Using Cloud Computing


“The Cloud” is an all-encompassing term for a virtualized information technology (IT) computing environment in which individuals and businesses work with applications and data stored and maintained on shared machines in a web-based environment, rather than physically located in a user’s location. Google’s popular email system, Gmail, is an example of the cloud, but this is just one model.

Cloud computing is here and virtually every organization is using it in some way, shape, or form. Educating yourself and your people on the opportunities and risks associated with this technology is of the utmost importance. Let’s look at the opportunities presented by cloud computing, managing the risks associated with housing your sensitive data offsite, using virtual computing environments, and vendor management considerations as you explore your cloud options.

There are actually three cloud service models — infrastructure as a service, platform as a service, and software as a service — deployed in four types of settings — private, community, public, and hybrid clouds.

Service models

Infrastructure as a service (IaaS) provides access to server hardware, storage, network capacity, and other fundamental computing resources.

Platform as a service (PaaS) provides access to basic operating software and services to develop and use customer-created software applications.

Software as a service (SaaS) provides integrated access to a provider’s software applications.

Deployment models

Private cloud is accessible from an intranet, internally hosted, and used by a single organization.

Community cloud has infrastructure accessible to a specific community.

Public cloud is accessible from the internet, externally hosted, and used by the general public.

Hybrid cloud is a combination of two or more clouds.

Cloud benefits

Cloud computing provides a scalable online environment that makes it possible to handle an increased volume of work without impacting system performance. Cloud computing also offers significant computing capability and economy of scale that might not otherwise be affordable, particularly for small and medium-sized organizations, without the IT infrastructure investment. Cloud computing advantages include:

Lower capital costs — Organizations can provide unique services using large-scale computing resources from cloud service providers, and then nimbly add or remove IT capacity to meet peak and fluctuating service demands while only paying for actual capacity used.

Lower IT operating costs — Organizations can rent added server space for a few hours at a time rather than maintain proprietary servers without worrying about upgrading their resources whenever a new application version is available. They also have the flexibility to host their virtual IT infrastructure in locations offering the lowest cost.

No hardware or software installation or maintenance

Optimized IT infrastructure provides quick access to needed computing services

The risks

Environmental security — The concentration of computing resources and users in a cloud computing environment also represents a concentration of security threats. Because of their size and significance, cloud environments are often targeted by virtual machines and bot malware, brute force attacks, and other attacks.

Ask your cloud provider about access controls, vulnerability assessment practices, and patch and configuration management controls to see that they are adequately protecting your data.

Data privacy and security — Hosting confidential data with cloud service providers involves the transfer of a considerable amount of an organization’s control over data security to the provider. Make sure your vendor understands your organization’s data privacy and security needs.

Also, make sure your cloud provider is aware of particular data security and privacy rules and regulations that apply to your entity, such as HIPAA, the Payment Card Industry Data Security Standard (DCI DSS), the Federal Information Security Management Act of 2002 (FISMA), or the privacy considerations of Gramm-Leach-Bliley Act.

Data availability and business continuity — A major risk to business continuity in the cloud computing environment is loss of internet connectivity. Ask your cloud provider what controls are in place to ensure internet connectivity.

If a vulnerability is identified, you may have to terminate all access to the cloud provider until the vulnerability is rectified. Finally, the seizure of a data-hosting server by law enforcement agencies may result in the interruption of unrelated services stored on the same machine.

Record retention requirements — If your business is subject to record retention requirements, make sure your cloud provider understands what they are and so they can meet them.

Disaster recovery — Hosting your computing resources and data at a cloud provider makes the cloud provider’s disaster recovery capabilities vitally important to your company’s disaster recovery plans. Know your cloud provider’s disaster recovery capabilities and ask your provider if they been tested.


What Are The Standards For Educational Evaluation


Educational evaluation is the evaluation process of characterizing and appraising some aspect/s of an educational procedure.

Common purposes in educational evaluation:

A. Educational institutions usually need evaluation data to demonstrate effectiveness to funders and other stakeholders, and to provide a measure of performance for marketing purposes.

B. Educational evaluation is also a professional activity that individual educators need to undertake if they plan to continuously review and enhance the learning they are endeavoring to facilitate.

Standards for Educational Evaluation

The Joint Committee on Standards for Educational Evaluation published three sets of standards for educational evaluations. Check for Educational Evaluations in US at UT Evaluators

A. The Personnel Evaluation Standards, published in 1988

B. The Program Evaluation Standards (2nd edition), published in 1994

C. The Student Evaluations Standards, published in 2003.

Each publication demonstrates and elaborates a set of standards for use in a variety of educational settings. The standards provide guidelines for designing, implementing, assessing and improving the identified form of evaluation. Each of the standards has been placed in one of four fundamental categories to promote evaluations that are proper, useful, feasible, and accurate.

A. The Personnel Evaluation Standards

The propriety standards ask that evaluations be conducted legally, ethically, and with due regard for the welfare of evaluatees and clients involved.

The utility standards are designed to guide evaluations so that they will be informative, timely, and influential.

The feasibility standards call for evaluation systems that are as easy to implement as possible, efficient in their use of time and resources, sufficiently funded, and viable from a number of other standpoints.

The accuracy standards require that the obtained information be technically accurate and that conclusions be linked logically to the data.

B. The Program Evaluation Standards

The utility standards are intended to make sure that an evaluation will serve the information needs of intended users.

The feasibility standards are planned to ensure that an evaluation will be realistic, prudent, diplomatic, and frugal.

The propriety standards are intended to make sure that an evaluation will be conducted legally, ethically, and with due regard for the welfare of those involved in the evaluation, as well as those affected by its results.

The accuracy standards are intended to ensure that an evaluation will disclose and convey technically adequate information about the features that determine worth or merit of the program being evaluated.

C. The Student Evaluation Standards

The Propriety standards assist to make sure that student evaluations are conducted lawfully, ethically, and with regard to the rights of students and other persons affected by student evaluation. For Educational Evaluations in US visit here

The Utility standards encourage the design and implementation of informative, timely, and useful student evaluations.

The Feasibility standards help ensure that student evaluations are practical; viable; cost-effective; and culturally, socially, and politically appropriate.

The Accuracy standards help ensure that student evaluations will give sound, accurate, and credible information about student learning and performance.

The Virtual Numbers Can Be Used By For Both Consumers And Businesses


A virtual telephone number is a phone number used to forward incoming phone calls on to another telephone number – the ‘destination number’. Check Virtual Numbers Can Be Used for Both Consumers And Businesses in Linkedphone

Virtual numbers can be used for many reasons by both consumers and businesses. Some examples:

1 Individuals use them to make it cheaper and easier for family, friends or business associates in another country to reach them

2 Small businesses use them to take calls or orders from customers based in another country

3 Large companies use them for customer service lines which are routed to call centers in other countries

Virtual phone numbers come in two flavors:

1. Virtual local numbers which use a regular local landline or mobile phone number as the virtual number. The virtual number has an area code associated with a specific geographic location.

2. Virtual toll-free numbers which use a normal toll-free phone number as the virtual number. The toll-free number typically has a generic area code associated with toll free calling. The number may be on a plan that allows toll free calls from a specific region or nationwide.

Both types of virtual numbers work roughly the same way, except for 2 main differences.

One difference is that virtual local numbers are free to the inbound caller if the the number’s area code is included as part of the caller’s calling plan. Callers from outside the local service area would need to pay any long-distance charges themselves. For example, if you had a local virtual number for Baltimore, then callers from in and around the Baltimore service area would be able to call that number for free. As well, people on nationwide calling plans might also be able to call the number for free.In contrast, with a toll-free number the inbound caller pays normally nothing regardless of where they are calling from – any long distance charges are passed along to the toll-free number subscriber.The second main difference is the monthly cost of a local vs. toll-free virtual numbers to the virtual number owner / subscriber. Generally, toll-free virtual numbers are considerably more expensive than local virtual phone numbers. Not only does the toll-free number have a higher baseline monthly subscription cost, but also the toll-free subscriber must pay any charges related to inbound leg of any calls.As a result, toll-free virtual numbers are generally not a viable cost saving solution for individuals, though they may work well for businesses.

Negative Space in UI Design: Tips and Best Practices

Tubik Studio

If you are looking for website design in Mumbai for your company visit  Vivid Designs

We often think that silence, emptiness or colorlessness is bad for us. We take them for granted without thinking that they are the solid foundation of the contrast. Only silence lets us know the value of the sound. Only empty space lets us understand what we want to fill it with. Only colorlessness lets us feel the colors brighter and deeper when they appear on stage. And only the absence of air lets us know how vital it is. Today we are talking about the air in design. Let’s discuss negative space.

What Is Negative Space in Design? Basically, negative space — or white space, as it’s often called — is the area of the layout which is left empty. It may be not only around the objects you place in the layout but also between and inside them. Negative space is a kind of breathing room for all the object on the page or screen. Not only does it define the limits of objects but also creates the necessary bonds between them according to Gestalt principles and builds up effective visual performance. Due to that, white space is a rightful design element that has a big impact on positive user experience. «White space is like a canvas: it’s the background that holds the elements together in a design, enabling them to stand out» — says Mads Soegaard from Interaction Design Foundation.

Negative space in graphic design is often seen in logos, on illustrations, posters and creative lettering where it becomes an active part of the visual presentation making key objects even more expressive. For example, in the blog illustration below we can see how the background element (moon) plays the role of contrasting negative space making the astronaut look more vivid and dynamic.

In UI design for websites and mobile apps, negative space is a big factor of high usability and navigability of the interface. The negative space around the layout elements is also called macro space whereas the space between them and inside (for letters and stroke elements) is also called micro space. For web design company visit Vivid Designs

What Is the Difference Between White Space and Negative Space? Short answer: no difference. These terms are fully interchangeable.

Why is this phenomenon called in two different terms? It’s easy to answer if you trace the origins. The term «white space» comes from print design since the times when pages were mostly white, so white space was everything around, between and inside the letters or symbols as well as around illustrations. Today, used in design, this term has nothing to do with white color: it’s all about empty space rather than color. The term «negative space» comes from photography: on a photo shot, they define positive space (objects attracting attention) and negative space (background).

What is important to remember that negative space in web design doesn’t have to be only white — you may use any color, texture, even pattern or background image.

Why Is Negative Space Important? Imagine yourself coming into a room fully packed with various staff. Shelves, boxes, bags, piles of books and clothes, the desk cluttered with various things. Will you be able to concentrate on such conditions? Do you really need all those things right now? Will you be able to find what you need and how much time will it take? Well, that’s pretty the same what users feel opening the page or screen without a vital air of negative space.

Both clients and some designers may want to put as many elements and features as possible on one page or screen thinking that it will save the game and will be helpful for clients. But that’s a mistake: in fact, users don’t need everything at once. Even more, too many elements without enough air significantly raise the level of distraction: overloaded with information and interactive elements most of which they DON’T need, users will have to take an effort to find what they DO need. As Aarron Walter mentioned, «if everything yells for your viewer’s attention, nothing is heard».

Among the benefits of a thoughtful approach to negative space in design, we could mention the following:

it supports scannability of the page it enhances visual hierarchy it makes the bonds between the elements visible and naturally perceived without additional means like tables, frames, arrows it provides enough air on the page so that it didn’t feel cluttered it sets user’s focus on core elements and reduces the level of distraction it adds style and elegance to the page. For example, let’s look on the landing page of Big City Guide. Here the designer applies a background photo and it plays the role of negative space on macro level. Even more, the elements of the photo and the lettering of the main copy element are interconnected: it makes negative space an active element of design and gives the page a united harmonic look.

Core Factors Influenced by Negative Space Using negative space properly may have a considerable impact on the following factors of user experience.

Readability and legibility If there’s not enough space between the elements, they become hard to read and demand additional effort. It may be a strong reason for eye and brain tense although many users won’t be able to formulate the problem. A proper amount of negative space, especially micro space, solves this problem and makes the process more natural. So, negative space directly influences the efficiency of typography on the page or screen. In music, pauses play the same role as sounds. In reading it works the same way: empty spaces placed correctly makes the text easier to read. For website development services in Chennai visit Vivid Designs

Branding If you check any logo guideline, you will find that designers define the appropriate amount of negative space around it so that it was perceived correctly. Breaking this rules is harmful to the visual performance.

Nature of the resource Negative space has an impact on the so-called design tone. For example, news resources will have less white space on the home page than blogs to set the mood and understanding that the platform is full of data which appears dynamically.

Attention ratio Enough negative space enhances visual hierarchy and allows users to focus on the key elements.

Based on that, negative space has an impact on visual perception in such aspects as:

copy content graphic content navigation identity. Let’s check a couple of examples. Here’s a home page for The Big Landscape. Without any visual frames and tables, due to the balanced use of negative space, the designer builds up the strong visual hierarchy and allows the user to scan various blocks of content in split seconds. This way design looks organized but light and airy. White background and layout arrangement make it look similar to a magazine page which harmonically informs the reader about the aims and nature of this online magazine.

Another example is a mobile application Upper app: here the negative space is all black, creating the great contrast to the core elements of the interface. For all the screen, only one straight line is used. Nevertheless, all the layout looks organized and highly readable due to enough air and no distractors. It also supports stylist minimalist elegance to favor aesthetic satisfaction.

Pitfalls to Consider 1. Confusing terminology. When you are talking to clients who may be not deeply familiar with design terms, make sure you explain the meaning of negative space before you describe the design solution. It may be hard for a non-designer to understand why «this screen needed more white space» looking at the totally black background as well as negative space may be associated with something bad — which it is not. So, don’t forget to dot all the i’s before using the terms.

2. Wish to reduce negative space to put more on page or screen. It happens not only in UI design: you may hear how an interior designer recommends saving some space to the client who wants 4 bookcases in one room instead of 2, or an architect explains why there is the need of empty space around the building to make it look and serve better. Even more, sometimes re-planning the elements with the better use of negative space creates the illusion of the room or building being bigger than it really is — and the same happens with data you have to put on a mobile screen or web page. Decide what’s more important, what’s secondary and what can be eliminated so that to navigate the user intuitively. Negative space will help to make the harmonic look of the screen or page even if it’s full of information and functions.

3. Poor prioritization. Negative space is not a cure-all if thought-out information architecture doesn’t stand behind an interface. Before you think about the design skin, you have to decide how a user will find the shortcut to his/her goal and solves his/her problem with an app or website. Plan this route before you make the looks presenting it in style; otherwise, even the best balance of visual elements including negative space won’t work effectively.


Building the user-centered web

What is a social network?

If you are looking for website development in Hyderabad for your company check Vivid Designs

I would like to reclaim some language:

Social is an adjective that means relating to human society and its members. A network is an interconnected system of things or people. Therefore, I’d suggest that we can define a social network as just being an interconnected system of people. The audience of this talk is a social network; so are your friends, colleagues, interest groups and so on. Social networking tools facilitate social networks. The universe of social tools certainly includes web applications with social functionality, but it also includes structured face to face interactions, telephone, post, SMS, email. In other words, the web is just one possible tool for this purpose — albeit a very effective one.

If you build it, they will come

You can’t install a social networking tool and instantly expect usage: Field of Dreams is not a good model for community development. The web is littered with ghost sites created using Ning, Elgg and more that have been established in the hope that a user-base will magically appear; however, if your main selling point is the social network itself, nobody’s going to join until that network of people exists and is actively using it. It’s a chicken-and-egg problem.

Therefore, you either need to have an existing network of people to facilitate interactions between (for example, when Facebook launched at Harvard) or compelling functionality that is useful without a network of existing users (for example, Delicious).

If we’re creating a tool that’s useful for the first user who signs up, without a pre-existing social network, then what we’re really talking is a software application that uses the web as an interface, and happens to have social functionality as one of its features.

The web as applications

When the web was conceived, it consisted of documents and pages linked with hypertext: linked words and phrases that, when clicked, would load another, relevant document. Each page had its own Uniform Resource Locator, which allowed you to return to that specific page at any time. Each page could be a destination in itself, and although the sites (collections of pages) could be linked together through hypertext, each one had no need to know about your activities elsewhere on the web. Why would they? Documents don’t have memory; their role is simply to impart information. For Top web design company visit Vivid Designs

Step forward to today, and the web is not entirely made of pages: applications now represent a large amount of the web. (Princeton WordNet defines an application as “a program that gives a computer instructions that provide the user with tools to accomplish a task”; Google Docs, Remember The Milk, Flickr, Delicious etc are all applications by this definition.)

The benefits are tangible: you can access an application’s functionality from any web-compatible device, anywhere in the world. You’re no longer bound to the software you happen to have installed on a particular machine, and you no longer need to worry about whether you’ve remembered to save a particular file onto a particular drive. Because of historic resource limitations, web applications tend to be easier to use, and entirely bypass the need for IT departments, which have unfortunately earned a reputation for being obstacles to productivity in many organizations.

This change of web usage has been reflected in the ongoing development of HTML, the markup language that all web interfaces are written in. The first four versions were largely orientated towards documents; however, HTML 5, currently in development, is the first version that explicitly contains functionality to support web applications. That includes offline storage and usage, sessions, and more advanced interface features. However, aspects of the document-orientated model remain.

Silos of information

Each application is its own atomic destination with its own URL, and is by default only aware of data created within it. That means we need to register for each application we want to use, fragmenting our accounts over potentially hundreds of products and company data centers, and that the documents, files and data we create within them can’t easily be shared with other applications. On my desktop, I can write a document in Word and open it in OpenOffice, or take a Paint doodle and load it in Photoshop, but there’s no easy, generic way to take my bookmarks from Delicious into another bookmarking tool, or to take my Google Docs and open them in Acrobat.com.

Currently, each web application is like a silo: they exist on their own, and if they interoperate at all, it’s through specific links between applications that have to be individually developed. Certainly, data created in an application stays in that application; sometimes you can check your GMail address book for contacts in order to find existing friends on a service you’ve just signed up to, for example, but it’s rare that you can actually export data fully into another product. As many of these services are free, a significant portion of their business models revolve around being able to control user-contributed data, keep users coming back, and sell user-generated activity data for marketing purposes. (One has to question whether the market for personal details will continue to be profitable, or whether, like the web advertising market before it, it will saturate and crash.)

In a social networking tool, the site model means that your contacts, the information you share and any detailed access permissions all relate solely to the application they were created in. However, collaborative spaces in social web applications are like documents: they’re one of the currencies of the social web. Just as I need to be able to use my wordprocessor of choice to edit a document, I need to be able to use my social tool of choice to collaborate with others.

Turning the model upside down

Right now, we have to register with each application we want to use. What if we required each application we used to register with us, in digital identities under our own control?

What if, using these identities, anyone could connect to anyone else, and anyone could store their data anywhere as long as the storage provider followed the same broad standards?

The web itself would become a social networking tool.

This is far more flexible, and future-proof:

Your ability to collaborate is not subject to a single company’s success: social functionality and application infrastructure are inherent in the web itself The possibilities for collaboration are not subject to technology beyond common open standards, which can evolve A wider range of application possibilities is ensured, because web applications gain the ability to interoperate in a general way Privacy and user control are established by allowing a person to determine which application has access to which data By establishing a general standard for social application interactions, the services and technologies used to make connections become less relevant; the Internet is people, one big social network, and users no longer have to worry about how they connect. We can all get on with communicating and collaborating rather than worrying about where we connect. For Web designing  services in New Delhi visit vivid Designs

User-centered identities

Under this model, providing the software that hosts your digital identity becomes big business. This hasn’t gone unnoticed by the main service providers, and they’re already fiercely competing to be your identity on the web:

Facebook wants your central identity to be a Facebook account (and arguably have made the user-centric model for the web part of their strategy for a very long time) Google wants it to be a Google account Twitter wants it to be a Twitter account Microsoft wants it to be a Live ID OpenID want it to be any OpenID-capable URL Because I use all of these services, the result is a very complicated identity space. These are a subset of my profiles:

For identities to be usable as a generic standard, you should be able to use any of these — or all of them. Nobody has just one facet (or persona) comprising their identity; everyone has a collection, representing the different parts of their lives. Ben Werdmuller the web strategist for hire doesn’t need to be connected to Ben Werdmuller the Doctor Who fan, who in turn doesn’t need to be connected to the Oxford resident. They can be connected if I choose to make them, but separating parts of your life is part of a user’s control over their identity.

However, that needs to be context-specific, not application-specific. Currently, for example, my Facebook account tends to be personal, while my Twitter tends to be professional. That doesn’t make sense: in order to write personally on Twitter, I either have to accept the collision of those two parts of my life, or I need to create an entirely separate, fragmented Twitter account. Wouldn’t it be better to be able to control who sees which interactions, and choose tools based on the functionality they add to a conversation? Otherwise you have the situation I present above: one identity per communication context per application. That will quickly become unmanageable, and the web will be littered with dead profiles.

Conversely, I believe the future of the web is in atomic digital identities based on permissive, open standards, linked together as an application framework.

How do we make this work?

Problem to solve: user control

First and foremost, the framework for decentralization must be established — in other words, the actual social mesh standards that will make it possible.

Technical mechanisms need to be established for controlling access to a resource or collaborative space, which should be easy to use without removing any of the flexibility of the platform, and should allow for the maintenance of multiple personas.

Another part of access control is allowing a resource to expire gracefully. It’s important to know when to lose data: sometimes documents, resources, spaces, personas or entire identities may be transient and only required for a certain length of time. There’s no need for everything on the web to exist indefinitely; currently, rigorous indexes like Google ensure that much of it does.

Finally, the tools and standards we create must be permissive of goals, content and structure that we might not have thought of. There certainly doesn’t need to be an overarching structure or taxonomy between individual identity spaces, and constraining the technology to a rigid set of activities and data types would limit the scope of the platform.

Problem to solve: ownership

Existing web applications tend to have a single-ownership model for resources. However, Silona Bonewald rightly pointed out to me that this isn’t always the case, and in a free-flowing social mesh, multiple ownership needs to be represented. For example, all collaborators on a resource should have ownership access, unless they explicitly choose to rescind that right.

In a company environment, a user’s employer may have shared ownership (or full ownership, with author access available to the employee). The same may be true with students in a university environment. On sites like Facebook, the service owner may in reality have some ownership rights over the content.

How can we maintain this granularity, but also retain user control?

Problem to solve: privacy & transparency

There is a very public attitude of “when you put something online, it’s published” in some parts of the software development community, which is a useful concept that gives developers carte blanche to share data freely. In a fully user-controlled environment, this public-or-completely-private binary situation can no longer be the case; a resource may have been published to a few select people. Ignoring this trait disallows the platform’s use in important environments like enterprises or public bodies.

When you sign up to a service, you agree to that service’s terms and conditions and privacy policy. However, your data may be farmed out to a collection of other, secondary services via APIs, without your knowledge or consent.

An important aspect of user control is knowing how your data is used and where it is transmitted by the applications you use, so I propose a simple, human-identifiable and machine-readable mark that:

Applies permissions to how my data can be used by applications (like Creative Commons does for shared content) Tells you in a visual way what happens to your data when you visit a site Incorporates multi-ownership It may be that these issues are addressed within the terms and conditions of a service. However, it’s very unlikely that a user will actually read the full contract. Therefore, a simple graphic icon with a link to a plain-English description, with an underlying microformat for machine-readable use, would be a welcome addition to the user experience. As the web becomes more mesh-like and data moves around more freely, conveying what happens to data owned by less-technical end users will become more and more important.

Problem to solve: platform

Finally, while it’s great having a conversation about this, these ideas aren’t useful to anyone unless someone goes ahead and builds it.

There are some existing projects and thinkers who are on these tracks:

The Diso Project is turning the WordPress open source blogging tool into a decentralized digital identity through an array of open standards, and the project’s Chris Messina has a lot of wise things to say about its development. Laconi.ca is a decentralized microblogging platform, whose Open Microblogging standard may be adaptable into a more widely-scoped technology. The Open Stack is a set of developing technologies that address some of the issues. Marc Canter’s Open Mesh treatise goes into detail on many of the issues. All of these are important contributions that strongly address some of the issues; however, we’re still a long way away from the vision of an open, social web.


I believe strongly, for the reasons stated above, that a decentralized, user-centered model for the web is the best way to advance it as an application platform.

Needless to say, I have my own ideas about how to actually build the platform, based on my Making the most of the web principles. However, it has to be a collaborative process: there’s no sense in building an open collaborative standard by yourself. My main concern is that the platform is created and works in an open, lightweight, flexible, easy-to-develop-for way while remaining secure and yielding control to the main user. The result will be an entirely new kind of platform, and presents a unique opportunity for anyone who wants to jump on board.


Service Oriented Architecture

If you are looking for website development in Bangalore for your company visit Vivid Designs

Application development has come a long way from developing inter-dependent components that serve the cause of a single application to building several independent modules, extending interfaces that can be called by any client, which communicate using asynchronous messaging protocols. Service oriented architecture constitutes of latter components.

Service oriented architecture or SOA essentially consists of various services that communicate with each other, usually in asynchronous fashion. These services are not bound to any particular language or technology and can be implemented by various means. They either communicate using exposed interfaces or some messaging model.

Some of the earliest acquaintances with SOA were using technologies like DCOM and CORBA. DCOM or Distributed Component Object Model was designed for use across multiple network transports. It is based on RPC or Remote Procedure Call and primarily works on Microsoft Windows. CORBA or Common Object Request Broker Architecture was developed keeping inter-operability in mind. A CORBA-based program from any vendor, on almost any computer, operating system, programming language and network can interoperate with another CORBA-based program from any vendor on any computer, operating system, programming language and network.

These technologies, however, haven’t been very popular with vendors for SOA-based applications because of their complexities and inefficient platform support. This is where Web Services comes into picture.

Web Services is an industry standard interface and connectivity technology. WSDL or Web Services Description Language, the interface description language used by Web Services, is self-describing and SOAP or Simple Object Access Protocol, its messaging protocol, is based on XML data interchange. It has fulfilled the long-awaited wish of enterprise application developers by truly separating the interface from the implementation and, because of its widespread adoption over the years, has become synonymous with service-oriented architecture. Its simplicity, openness and wide-spread use has changed the landscape of Enterprise Application Integration giving traditional EAI companies a run for their money.

Many companies all over the world are phasing their existing applications to service oriented architecture to make their business applications accessible to the clients and business partners, and to improve information sharing.

SOA has changed the way enterprise applications are built, with the lines between application development and application integration gradually fading.


You got the client, now it’s time to set your web design schedule

In Part 2 of the PMGEP (Project Manager’s Guide to Extraordinary Projects) we covered the contract process and the importance of having a signed agreement in place before any work begins.

Now that the contract has been signed its time for you and your team to get to work! However, before you start churning out wireframes and comps all nimbly bimbly, you need a plan of attack in the form of a web design schedule.

Developing and maintaining a schedule is the single most important function of a Project Manager’s job and plays a HUGE role in the success of a project. If you don’t take the time to plan out and set the project’s milestones and delivery dates, it will no doubt lead to confusion between you, your team, and the client. But not to fear! I’m going to show you the process that I use to get every project off on the right foot.

Start with what you know Before you start throwing random delivery dates on to a calendar, let’s first start with what you know about the project. When is your client’s desired completion date? Most clients have a timetable in mind for their project and it’s likely that date was made clear during the contract phase.

Once you have that date, you now know two very important pieces of information that you’ll need when building a schedule; when you start (when the contract was signed) and when you stop (upon completion). Now you just need to fill in the gaps!

If you don’t take the time to plan out and set the project’s milestones and delivery dates, it will no doubt lead to confusion between you, your team, and the client. By now, you probably have all of the requirements in hand since the majority of these (if not all) should be written in to the agreement between you and your client.

However if you’re still unclear as to what the client is expecting, now is the time to get the requirements solidified.

Assuming you have these things in place, you should have the information you need to begin planning out your web design schedule. As I think most would agree, a single page contains many layers that need to be addressed before moving on to development.

A page needs to be brainstormed, wire framed, designed, and signed-off on before it can be coded. And since a home page design then typically dictates and influences the look of subsequent interior pages, it’s likely that you’ll be able to plan the secondary pages shortly there after. f you are looking for Web development company check Vivid Designs

Simply thinking your way through the requirements and mapping out how to get from A to B will help you put deliverables in the proper order on your project schedule. Once you’ve outlined the order of events, you can then begin filling in delivery dates for each item. But how long does it take to complete each of the tasks you’ve put on your schedule?

Getting your web design ducks in a row Trying to allot the proper amount of time per task is important since there are many variables that could possibly affect completion time. You need to factor in not only time spent doing the work, but also time for client feedback and subsequent revisions.

We’d all love it if we nailed a design on the first try, but you can’t expect that to happen every time. We’d all love it if we nailed a design on the first try, but you can’t expect that to happen every time. You have to allow time for dialog between you and your client and build in extra hours to make changes to your work based on those conversations. If you’re not sure how long a particular task will take you, heck even if you do know, try and add in more time for completion of that deliverable.

Believe me, your client won’t be upset if you over estimated and deliver early, but you can bet you’ll be getting an earful about it if you miss a deadline that YOU set!

The client impact Even though your team will be responsible for most of the deliverables, it is important that you don’t forget to assign your client their own “homework” as well.

If they take a look at your project schedule and don’t see their name anywhere, they might be more likely to go into cruise control mode thinking that your team has it all covered.

A client needs to know that the success of a project depends just as much on their involvement as it does yours. Timely feedback, project priority checks, and constant communication are all responsibilities of a good client. If they fail to meet a milestone assigned to them, they need to understand that it could negatively impact a deliverable scheduled down the line; which could potentially push back their desired launch date and completion.

Keep in mind that if you don’t assign your client any action items and they fail to provide the feedback you need, you will have a very difficult time trying to explain that the deadline you missed was anyone’s fault but your own.

Review, review, and review some more At this point you should have a pretty concrete schedule outlined, but you aren’t quite ready to send it over to your client. Even though you can become quite familiar with how long a given task usually takes the team, it’s always important that you review your schedule internally before unveiling your timeline to the client.

It’s important to review your schedule internally before unveiling your timeline to the client. Your team of web designers and developers may be more familiar with the intimate details of a deliverable and can point out that it may take significantly more time to complete than you’ve allocated. Take this juncture to collaborate and make necessary adjustments since it will be far much harder to backtrack once the project schedule has been finalized.

Also, now is not the time to forget about your other clients! Many firms carry more than one client at a time and many have the same resources working on both projects. Be sure that you review your other project’s schedules to make absolutely sure that you haven’t “double-booked” your teammates by giving them two major action items that are due on the same day. For Web development company in Bangalore visit Vivid Designs

Spacing out delivery dates between projects can not only lessen the stress levels of your team members, but can give you a slight cushion if something goes wrong on one project and you need to temporarily shift your resources to another project.

The web design schedule for all the world to see Once you’ve dotted all of your i’s and crossed all of your t’s, it’s time to send your schedule to the client for review and sign-off. They may suggest additional edits which could send you back to the drawing board, but their input is vital to forming an extraordinary schedule that will put your project on the fast track to success.

When everyone agrees on the final schedule, I recommend putting the milestones and delivery dates on to a calendar that everyone can access. Whether you use something like Basecamp or a Google Calendar, having the schedule in a central location will allow everyone to check up on the project if they have a question about when something is due or what’s next on the agenda.

I also recommend that you review the schedule at various points throughout the life cycle of the project. Just because everyone can access the schedule doesn’t mean they actually read it!

Typically I like to review the project schedule in detail on a kick-off call at the beginning of the project, and then after each major milestone. That way there is very little chance that something will be missed or that someone isn’t aware of what is expected of them.

Be like water There is a famous quote by the legendary Bruce Lee that reads, “If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water my friend.” In short, what he’s saying is that you have to be willing to adapt to situations and environments if you want to succeed.

“If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water my friend.” — Bruce Lee This kung-fu metaphor speaks volumes of the importance of maintaining your schedule once it has been put in place. Things happen over the course of a project that can throw your carefully laid plans out of whack. Requirements change and unforeseen snags can take longer than expected to resolve. While it is important to stick to the schedule and drive toward your goals, you can’t be afraid to rework your schedule if the project landscape changes.

If this happens, be sure to set a new schedule that fits the new requirements. Don’t just start plugging away at the old deliverables knowing that the dates are no longer valid. Wash away the confusion by being proactive and make the necessary adjustments the project requires. Be like water.

And another one… Hopefully this article has given you some good advice on how to set your next project schedule. While everything most likely won’t go according to plan, the important thing is that you are constantly thinking about the plan and working towards set goals.

But remember, a web design schedule is just the road map, you still have to stay behind the wheel and steer. It’s up to you to do your best and put your team and the project in a position to succeed. That’s right, now drop and give me 50!

P.S. Check out Part 4 of the PGMEP where we’ll take a look at time tracking and how starting to watch the clock now can help you and your team on future projects!


Audi Q3 Engine & Transmission

Audi Q3 Overview

When it was launched in 2012 the Q3 was Audi’s shift in focus from distinguishing itself in a new market to boosting its sale numbers and targeting a new, younger customer over your regular 45+ something Indian millionaire/billionaire. At just a couple of lakhs over the price of the entry level A3 sedan, the Q3 still isn’t far away from the entry ticket (A3 sedan) into the Ingolstadt marque’s luxury club. It’s been facing some stiff competition from the BMW X1 and the GLA of late and the next generation update is still about a year away. Can a new frugal petrol engine, and an also new, frugal and more powerful diesel mill encourage you to put your money on the four-ringed contender? Check for Audi cars Price, Review & Specifications at CarzPrice

Audi Q3 Design

The Q3 cuts a handsome figure and the silhouette remains the same in the 2017 Q3 as well. The updates include a redesigned bumper, large faux air dam and some more plastic cladding. The cladding on the doors features streaks that look distinctive and much better than featureless plastic on the sides of the door. The update also includes standard 17-inch alloy wheels as well as LED headlamps and tail lamps as standard across the range. The Q3 also gets dynamic turn indicators, which is steadily turning out to be a signature Audi feature

Audi Q3 CAbin

There are no major changes to report in the cabin. The Audi Q3 carries forward with the same neat dashboard and generally user-friendly interior. Quality is up there with more expensive Audis and though the seats are not real leather but leatherette, the ambience inside is what you’d expect in a premium SUV. You sit reasonably high up in a Q3, the front seats are generous in size and support and even the rear seat is spacious enough for two adults to sit in comfort.

With the update, Audi has streamlined the variants on offer. The 30TFSI and 30TDI can only be had in Premium trim while the 35TDI is available in Premium Plus and Technology trim too. What is nice is that even the Premium variants get much wanted goodies like a panoramic sunroof and electrically adjustable front seats. The Premium Plus trim doesn’t get more features but adds in richer aluminium-look inlays. The top-spec Technology variant is pricey but your money does get you paddle shifters, SD card-based navigation, a reverse camera and a colour multi-info display in the instruments binnacle among other features.The Q3 runs Audi’s MMI infotainment system. It is easy enough to use but the interface doesn’t look as slick as that in the newer Audis and there’s no Android Auto or Apple CarPlay support either.

Audi Q3 Engine & Transmission

The smooth, 1.4-litre TFSI petrol motor in the Q3 develops 150PS at 5,000-6,000rpm and 250Nm between 1,500-3,500rpm. While the figures may seem paltry for the price of an SUV, it’s a pleasant surprise to discover that the petrol Q3 never feels as if it’s run out of breath. This is evident in the 9.5s it took to cover the 0-100kmph dash. The 6-speed, dual-clutch transmission also does a brilliant job of keeping the Q3 in the power band at all times. The Q3 gets four driving modes – Efficiency, Comfort, Auto and Dynamic, each altering the steering, acceleration and shift points. Comfort and Auto is ideal for commutes in the city, but if you are in the mood for some fun, the Dynamic mode offers quicker acceleration as the shift points moves to the redline, making full use of the engine’s power.

Efficiency, as the name suggests, optimises the aforementioned parameters to deliver the best possible fuel economy. The gearbox, in this mode, shifts to the next gear just under 2,000rpm and if you lift off to coast, the revs drop to 800rpm, thereby saving every drop of fuel. Which is why there’s no surprise that petrol Q3 returned 10.7kmpl in the city and 15.8kmpl on the highway, which is actually quite impressive. The figure, however, I presume, could have been even better if Audi would’ve not skipped the 1.4 TFSI’s Cylinder On Demand feature. The system shuts off two cylinders while cruising between 90-125kmph or at low speeds (25-40kmph) and this feature is available in the 2017 A3 sedan.

While the petrol is really good, the 35 TDI engine is the one that takes the cake. What hits you first is the sheer refinement of this motor, and the way the tacho needle races to the redline.And then there’s the performance. The 184PS, 380Nm engine propels the Q3 from 0-100kmph in just 8.1 seconds, and our tests revealed that in-gear acceleration too is quicker than the petrol Q3. While performance has improved, fuel efficiency surprisingly remains pretty much the same as what the previous Q3 returned. At 12.9kmpl in the city and 18.1kmpl on the highway, the diesel Q3’s efficiency is also at par with its segment rivals.

Audi Q3 Ride & Handling

The ride quality of the Q3 is on the firmer side when compared to its silky smooth Q brethren – the Q5 and the Q7. That said it’s still perfectly composed over any obstacle you will encounter in town. From small to large bumps you remain quite isolated and comfortable. There is also very little vertical or lateral movement from uneven surfaces too. There are some differences in the way the petrol and diesel behave on the road and out on the highway the petrol tends to feel a little flighty, due to some unnerving bouncy vertical movement at high speed, and this may be down to its lighter kerb weight; the diesel on the other hand with a heavier kerb weight and four wheel drive is unsurprisingly more planted on the highway. For information on contact details of Audi car dealers in Hyderabad visit Audiprice.in

The steering is quite light and this is excellent when navigating through city traffic and parking in tight spaces, but when you up the pace through a set of corners you’ll soon find it lacks any feedback. The chassis is quite nice when pushed, with the suspension handling any challenge our bumpy roads care to throw its way. There is a little bit of body roll when you push the car but this too is controlled and soon you can learn to trust the front and let the suspension handle the rest. The petrol engine with its gruff rumble and desire to rev is quite nice when your evil twin shows up behind the wheel, but it’s again let down by the lack of pedals that would have allowed better use of the gearbox while keeping both hands on the wheel. The diesel with its smooth spread of 380Nm of torque is again the more fun of the two even when you’re hooning around.

Audi Q3 Braking and Safety

Audi Q3 is equipped with plenty of braking and safety features for driving control and passenger protection. The primary braking of the wheels is operated by the Ventilated Disc front and Solid disc rear brakes. Moreover, this luxury compact SUV is also equipped with advanced braking features like Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), Electric Braking System (EBS), Traction Control and Electronic Stability Programme.

Audi Q3 Price In Hyderabad

Audi Q3 Ex-Showroom Price in Hyderabad ranges from 33,40,000/- (Q3 30 TFSI Premium AT FWD) to 41,54,250/- (Q3 35 TDI Quattro Technology). Get best offers for Audi Q3 from Audi Dealers in Hyderabad.

Audi Q3 Verdict

With the introduction of the new petrol engine and by skimping on some features like a reverse parking camera, paddle shifters and the higher resolution instrument cluster screen, Audi has managed to keep the low entry price for the Q3 range similar in the hopes of attracting a few more buyers. But really the pick of the bunch is the new diesel. It’s a much more pleasant driving experience, is quattro equipped and also doesn’t skimp out on features that the petrol misses.If you feel that the badge on the car is worth sacrificing some creature comforts for, and you’re sure you will never feel the urge to mash that throttle pedal, and with no one wiser that your pride and joy is slightly lacking in displacement, the petrol (five lakhs cheaper than the diesel) may make enough sense.
