Cloud computing is defined to be Internet based computing technology, where the term 'Cloud' simply means Internet - and cloud computing refers to services that are accessed directly over the Internet. There are essentially three categories of cloud computing. Iaas (Infrastructure as a Service) - number crunching, data storage and management services (computer servers), SaaS (Software as a Service) - 'Web based' applications, and PaaS (Platform as a Service) - essentially an operating system in the cloud. Much of the attention and literature has focused on the revolution in Iaas services provided via the cloud.
