IT as-a-Service Using Cloud Computing and How it is Changing Organizations Today

There are many challenges when building a reliable, flexible IT infrastructure that can manage unpredictable behaviors of today's internet-based business environment. But Cloud-based IT is changing the way organizations used to look at building and maintaining IT infrastructures.  The digitally dynamic business world can no longer be served effectively using a static IT architecture.  To be competitive, businesses need to re-think the IT as an on-demand sharing of resources using the Internet - a totally a web-based platform that provides IT services to employees anytime/anywhere in the world.The idea of cloud computing is nothing new. There's a good chance you've already used some form of cloud computing. If you have an e-mail account with a Web-based e-mail service like Hotmail, Yahoo! Mail or Gmail, then you've had some experience with cloud computing.  Imagine taking your IT closet, including all that it hosts, and put on the cloud while virtualizing the desktops.  That is what Cloud IT offers.

Think of cloud computing as the ability to provision computational resources on demand via a computer network. Take for example; when a user executes a task, such as launching Word processing application, or opening a contact management database, these tasks taking place without actually possessing the software using a local hardware (the user's PC). In fact, the end-user's computer may contain very little software or data, if any at all.  A display terminal connected to the Internet with a minimal operating system and a web browser.  The cloud is the underlying delivery mechanism, the user's desktop and all the required business applications can be served on the cloud by the cloud on-demand. 

In such an unstable economic environment, budgets are under scrutiny and companies are feeling increased pressure to reduce operating costs without sacrificing quality. At the same time, in order to remain successful and competitive, a business cannot forego investment in areas such as IT that has proven to be a major differentiator among competitors.
