Cloud computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet. A Cloud services platform such as Amazon Web Services owns and maintains the network-connected hardware required for these application services, while you provision and use what you need via a web application.
With the recent exploration of cloud computing technologies, organizations are using cloud service models like infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) along with cloud deployment models (public, private and hybrid) to deploy their applications.
