The cloud computing revolution: -

The Web 2.0 revolution has brought us many new concepts and cloud computing is one of them.

The term "Cloud Computing" comes from the use of an image in the cloud to represent the Internet. We rely heavily on this "cloud" to send and receive data reliably. There were data channels, routers and servers and now there are services. Cloud computing covers the entire spectrum of provision of services hosted on the Internet. These services are generally classified into three categories:

1. Infrastructure as a service (IaaS): for example. Amazon
2. platform as a service (PaaS), for example, Google Apps
3. Software as a service (SaaS): for example. Web-based emails

It is elastic (the user can have as much or as little service as he needs) and the provider manages it completely (the user only needs a computer and Internet connection).
