Cloud computing is the next stage in evolution of the Internet. The cloud in cloud computing everything from computing power to computing infrastructure, applications, business processes to personal collaboration. Cloud computing can be delivered to you as a service wherever and whenever you need over the Internet. With cloud computing, the consumer needs nothing but a web browser and Internet access. The web browser can be a traditional desktop or laptop PC, a Net book, or a mobile device such as a PDA, smart phone like Blackberry or iPhone.

The cloud itself is a set of hardware, networks, storage, services, and interfaces that enable the delivery of computing as a service. Cloud services include the delivery of software, infrastructure, and storage over the Internet (either as separate components or a complete platform) based on user demand.

The concept of cloud computing is one of a user sitting at a terminal taking advantage of services, storage space, and resources provided somewhere else, on another computer, through an Internet connection.

Example, if I’m the user, my word processor documents may be stored on one computer; along with the program I use to edit the documents. My pictures and videos are stored on another computer. My email is saved on a third machine that I can access from any workstation. I also have a personal calendar, photo album, links to favorite sites, and more saved in cyberspace.

SO Where is my documents, email, favorites and pictures? If you ask me, I will just say Google Docs, Hotmail, Scrapblog and Flickr. I will just give you the URLs. But if you ask me to draw a map for the specific location, I will be very confuse!!!. In fact, I don’t know. My emails might be in LA and my documents were in DC. Then they’ve been moved to other servers. But the URLs haven’t changed.                             I just know is that they’re “out there” – in the cloud…
