CLOUD BASED TECHNOLOGY
Cloud services cover a wide range of resources that a service provider delivers to customers through internet, which is broadly known as the cloud. There are various characteristics of cloud services like self-provisioning and elasticity which implies customers can provision services on an on-demand basis and close them when they are no longer necessary. In addition, customers usually subscribe to cloud services, under a monthly billing arrangement, rather than paying for software licenses, supporting server and network infrastructure upfront, for example. In many transactions, this approach makes a cloud-based technology as a part of operational expense, rather than a capital expense. From a management viewpoint, cloud-based technology lets organizations access software, storage, and other IT infrastructure elements without handling the burden of maintaining and upgrading them.
The usage of cloud services has become closely associated with cloud offerings, like Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).
