CLOUD COMPUTING

CLOUD COMPUTING

Cloud computing is the next stage in internet evolution, providing the means through which everything -- from computing power to computing infrastructure, application, business process to personal collaboration -- can be delivered to you as a service wherever and whenever you need.

Cloud computing has four essential characteristics: elasticity and the ability to scale up and down, self-service provisioning and automatic de-provisioning, application programming interfaces (APIs), billing and metering of service usage in a pay-as-you-go model.  This flexibility is what is attracting individuals and businesses to move to the cloud.

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 to all their constituents.
  • The cloud service provider who is responsible for IT assets and maintenance.
