What is cloud computing?

Rather than give you a dry definition, let me explain it with examples.

Once upon a time, you first downloaded your email to the local computer before you could read and reply to them.

All your mail stayed on that single computer, meaning you cannot access the downloaded mail from anywhere else. This is known as POP3 mail.

To be able to do the downloading, you need to first install a software, known as mail client. Examples of mail clients are: Eudora, Outlook, Thunderbird, etc. One downside to this method of managing your mail is that, if the computer on which your mail resides crashes, you lose all your mail also.

This method of managing mail has changed. Today, you no longer need POP3. It has been superseded by IMAP. You simply need a web browser to manage all your mail. First you sign up for an account with email providers such as yahoo, gmail, hotmail, etc. With a browser, and Internet access, you simply login from anywhere to manage your mail.

The idea of managing mail from anywhere, is a form of cloud computing.

How about we extend the same idea to everything else you do on your computer, such as word processing, graphics design, playing games, etc?

This is what cloud computing is all about. Just as in the case of email, you just need a web browser to manage word processing, spreadsheets, graphics design, games, etc. Any files you create will be saved on the remote server. If your local computer crashes, you don't lose any data, since all your data resides on the server.

This style of computing is known as Cloud Computing. With cloud computing, you no longer need to install your own copy of Microsoft Office, media player, accounting software, etc. A web browser is all you need for everything. Since every computer has a browser, it means you can work from any computer.

This is where computing is headed today.

Cloud Computing is the new buzzword in the computer world. Now you know what it all means.
