Cloud computing is Internet based computing where shared resources, software and information are provided to computers and other devices on demand. It describes a new delivery model for IT services based on the Internet. The word cloud is a metaphor that is used to describe the Internet and is derived from the cloud drawing that has been used in the past to represent the telephone. Typically speaking, cloud computing providers provide business applications which are then accessed from another web service and the data is stored on servers.

In most cases, cloud service customers do not own the physical infrastructure, thus avoiding capital expenditure because the usage is being rented from a third party. The resources consumed are done so as a service and customers only pay for the resources that they use. Some companies provide their services as a subscription based service, while others use the utility computing model. The utility computing model is similar to how utility services, such as electricity, are used.

The security of cloud services may be delaying the adoption of its more widespread usage. The Cloud Security Alliance is a nonprofit organization Cialis that promotes the best practices of providing security assurance for cloud computing. While there have been no published studies to confirm the assumption, it has been referred to as a form of green computing. The lack of need for software installation is a great highlight for cloud service clients. One less thing to own is one less thing to worry about.
