What is Cloud computing?

According to Dummies.com

Cloud computing is the next stage in the Internet's evolution, providing the means through which everything — from computing power to computing infrastructure, applications, business processes to personal collaboration — can be delivered to you as a service wherever and whenever you need.

The world of the cloud has lots of participants:

  • The end user
    • who doesn't have to know anything about the underlying technology.
  • Business management
    • who needs to take responsibility for the governance of data or services living in a cloud. Cloud service providers must provide a predictable and guaranteed service level and security to all their constituents. 
  • The cloud service provider 
    • who is responsible for IT assets and maintenance.

According to
cloud-distribution.com

Cloud Computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams.
