Soaring high into the clouds or "understanding Cloud Computing".

Cloud computing is the new buzzword of IT, that have actually been gaining so much attention. "What is cloud computing?" is the question that never seems to go away. No matter how much people try, a universally agreed-on definition remains elusive because it seems a little confusing or difficult to understand it grasp its concept given other IT Computing trends such as Virtualization, Hosted IT, Unified Computing which are all related ones.
The concept of "Cloud Computing" is one that is spurring so much interest, raising so many stakes and defining a potential change in how enterprises IT networks and the internets will be handled.
Cloud computing is a concept that turns computer processing and storage into a service. Tim O'Reilly simply put it in this way, “It’s one of the foundations of the next generation of computing. It’s a world where the network is the platform for all computing, where everything we think of as a computer today is just a device that connects to the big
computer we’re building. Cloud computing is a great way to think about how we’ll deliver computing services in the future.” In other words, it is a combination of scalable and elastic IT-enabled capabilities delivered as a service to external customers using Internet technologies.

Instead of installing applications locally, customers outsource computing tasks to providers whom they pay based on factors such as the amount of processing time they consume. Unlike dedicated hosting, in which a third-party hosts particular servers on behalf of their customers, cloud computing offers storage and processing power that can scale up on demand. This on-demand delivery of computing resources is known as virtualization, a process that separates applications and other services from a traditional one-to-one correspondence with the servers from which they are delivered. Virtualization is different from clustering, another approach that expands computing power, in that the application is not restricted to a fixed number of servers it can access. Instead, it can tap into the full inventory of systems that a service provider maintains, giving the application access to a data center's worth of potential computing resources.

Today, cloud computing technology is still taking shape. In fact, the definition of the term remains somewhat nebulous. From some perspectives, cloud computing is simply an old idea re-branded. The use of the Internet for on-demand computing has a history of generating great interest but only moderate customer demand, which suggests two alternative futures for cloud computing.
In one potential future, it joins grid computing and utility computing as a niche offering. After all, it is not a radically new technology, but a variation on a familiar theme. In the other potential future, however, cloud computing becomes a common means by which enterprises access software, processing, and storage, with on-demand services acting as alternatives or supplements to traditional LANs and WANs. This outcome is suggested by the fact that for years, many of the largest, most influential players in the IT market have continued to see outsourced computer processing as a lucrative business and continue to work hard at finding the right blend of features and pricing to make the idea more successful.
Overall, Cloud Computing seems to be having a huge potential in the future operation and performance of data centers, and holds the promise of allowing us to better and optimally manage and share information online. But, how secure is it? This represents another hot and indispensable topic on which we will weighing in soon. Stay tuned!
