cloud computing...what's that??

Cloud computing is becoming more and more popular these days, but what does it means exactly of the term "cloud computing"??

The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams. Cloud computing as defined, is location-independent computing or remote computing where you can access information from anywhere.

These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). So, what sets cloud computing apart from the rest?? The answer is simple, cloud computing are sold based on demand...typically by the hour or some even by minutes. Hence, the user is able to have the service at any given time or quantity as the service is managed by provider. Therefore, only a computer and Internet access is needed.
