What is Cloud Computing?
Cloud computing is a new computing technology refers to the on-demand provision of computational resources via a computer network, rather than from a local computer. Users or clients can submit a task to the service provider, without actually possessing the software or hardware. The consumer's computer may contain very little software or data (a minimal operating system and web browser only), serving as a basic display terminal connected to the Internet. Since the cloud is the underlying delivery mechanism, cloud-based applications and services may support any type of software application or service in use today. Cloud computing service in short is called "The Cloud".
Previously both data and software had to be stored and processed on the computer. The development of Local Area Networks allowed for a system could be organized to increase the performance of the entire system. In an extension to that concept, cloud computing fundamentally allows for a functional separation between the resources used and the user's computer, usually residing outside the local network Consumers now routinely use data-intensive applications driven by cloud technology that were previously unavailable due to cost and deployment complexity.
In cloud computing, any computer connected to the Internet is connected to the same pool of computing power, applications, and files. Users can store and access personal files such as music, pictures, videos, and bookmarks or play games on a remote server rather than physically carrying around a storage medium such as a, pen drive or DVD Even those using web-based email such as Gmail, , Yahoo! or Outlook are making use of cloud email servers. Hence, desktop applications that connect to internet-host email
