Characteristics of cloud providers include self provisioning and elasticity, that’s, clients can provision services on an on demand basis and shut them down when no longer necessary.

Cloud services which a service provider offers to numerous clients throughout the world wide web are referred to as public cloud services. The SaaS, PaaS and IaaS providers noted above might all be said to be providing public cloud based services.
Private cloud services, in contrast, aren’t made usually available to individual or corporate users or subscribers. Private cloud based solutions use technology and approaches associated with public clouds, like virtualization and self service. Private cloud services operate on a company’s own infrastructure and are committed to internal users, as opposed to multiple, external customers. The 2nd sense of cloud services include professional services that enable clients to deploy the numerous kinds of cloud services. Consulting firms, systems integrators along with other channel partners might offer such services to help their customers adopt cloud based technology.
