Cloud computing is a technological model that provides web based applications, middle-ware, and computing resources on demand. When enterprises deploy technology as a service, end users are only provided with resources that they will need for the particular tasks. This in return prevents clients from paying extra money for idle computing resources.

Cloud computing concept also goes beyond normal cost savings; this is so because technology is usually accessed from a remote service provider directly from their servers rather than on local system.

In cloud computing there are various actors who have different roles within the cloud computing value added network. This concept comes with an array of opportunities from the cloud computing platforms which integrate services that provide additional value, not mentioning the complex services which give rise to new set of roles.

Actors existing on a cloud environment

The platform provider provides an environment that makes it possible to deploy cloud based applications. This particular platform provider ensures the technical basis for the marketplace where cloud related services are usually provided.

Finally there is the consulting that provides support to the customers to select and implement relevant services which can create value for the client's business model.

Benefits of cloud computing to the enterprise
Cloud computing comes with a host of benefits to the organization regardless of its size. To begin with, enterprises deploying cloud computing stand to benefit from reduced costs as a result of less expenditure on hardware, software's, networking management, and overall IT expenses because clients only pay for what they consume.

There is also scalability aspect due to the fact that enterprises scale their business storage needs seamlessly rather than having to make expensive purchases in terms of expensive applications or hardware. There is also the benefit of automatic updates which is done remotely by the cloud provider.
