Cloud Computing Cloud computing is a computing paradigm shift where computing is moved away from personal computers or an individual application server to a “cloud� of computers. Users of the cloud only need to be concerned with the computing service being asked for, as the underlying details of how it is achieved are hidden. This method of distributed computing is done through pooling all computer resources together and being managed by software rather than a human.

Characteristics of Cloud Environments 1. On-demand self-service: This means that cloud customers can sign up for, pay for and start using cloud resources very quickly on their own without help from a sales agent. 2. Broad network access: Customers access cloud services via the Internet. 3. Resource pooling: Many different customers (individuals, organizations or different departments within an organization) all use the same servers, storage or other computing resources. 4. Rapid elasticity or expansion: Cloud customers can easily scale their use of resources up or down as their needs change. 5. Measured service: Customers pay for the amount of resources they use in a given period of time rather than paying for hardware or software upfront.
