Basically, these services fall into three categories: Software-as-a-Service, Infrastructure-as-a-Service and Platform-as-a-Service. A cloud service is different from traditional hosting. It can be sold by the hour or minute. A user can buy the amount of service they want. The customer only needs a personal computer and access to the Internet; the service is managed completely by the provider. Interest in cloud computing is due to important introductions in virtualization and improved access to high-speed Internet.

If the cloud is public it sells services to anyone on the Internet. For example, Amazon Web Services is a huge public cloud provider. A private cloud provides hosted services to a limited amount of people. A virtual private network is the result of a service provider using a public cloud to create their private cloud. Whether the cloud is private or public, cloud computing provides access to computing and information technology services.

Infrastructure-as-a-Service like Amazon Web Services provides virtual server instance to start, attain and assemble their virtual servers. Platform-as-a-Service in the cloud is a set of software tools hosted by the provider. In the software-as-a-service cloud model, the vendor provides the hardware and the software product and acts with the user.
