For some people the concept cloud computing is as nebulous and difficult to grab hold of as a literal cloud. But the idea is actually very simple.
Cloud computing has nothing to do with clouds in the sky. In pictures explaining computer networks, a diagrammatic cloud is often used to depict the internet – over time a cloud became a metaphor for the internet.
To grasp cloud computing fully you must first understand how the internet works. The internet is a worldwide network of computer networks. Data is stored on servers spread across the globe – any server linked to the network of networks (the internet) can be accessed by anyone who has permission to use it.
The internet can be entered through:
your home computer
your mobile computer
your friend’s computer
a computer at your school
your cell phone (if it is web enabled).
You can store data on the internet in the same way that you can retrieve data. Such data can be text, pictures or even video clips. Much of the information storage space is available at no cost to you for personal use.
Cloud computing means that you no longer need to carry your information with you – it is stored in the internet cloud – all you need is an access instrument and a gateway into the internet.
If you are using Facebook, Twitter, Plurk, Google Docs, e-mail and blogs you are already practicing cloud computing.
With this simplistic explanation of cloud computing you can keep your feet firmly on the ground while reaching for the clouds.
