Cloud computing is commonly used to represent any work done on a computer, mobile or any device, where the data and possibly the application being used do not reside on the device but rather on an unspecified device elsewhere on the Internet. The basic premise of cloud computing is that consumers (individuals, industry, government, academia and so on) pay for IT services from cloud service providers (CSP). Services offered in cloud computing are generally based on three standard models (Infrastructure-as s service, Platform-as a service, and Software as a Service) defined by the National Institute of Standards and Technology (NIST). The reason for cloud existence is to resolve managing problems being faced for data that were excessively stored, either mandatory capacity was limited due to the infrastructure of the business, or large capacity that led to a wasted capital. Apart from those major factors such as the initial capital, capitals and the service-fix cost, the sophisticated effort for the patching, the managing and the upgrading of the internal infrastructure is a huge obstacle for firm‘s development and mobility. For many firms where client and cultural competency have not got the strength to manage large data center environments and infrastructure, it would be wise to upload their files or data backups to another machine via internet, in order to concentrate more on the organizations primary objectives.
