A world without Internet is possibly unimaginable. The phenomenon which started in the 1960s with a military research and development revolutionized the way things are perceived today. A similar prelude is being anticipated with cloud computing in the second decade of the 21st century.

Cloud Computing had been incepted in the final years of 20th century. It has been an initiative to put together the Internet and business technology to provide greater flexible solutions to organizations. The basic idea is to interconnect many computers through hardware resources, virtual hardware resources and syncing them with software running on multiple systems. This facility is further opportune for storage purposes with the documents or else in its different forms of files being stored with a worldwide accessibility making use of various devices as platforms. The various platforms as of now are the PC, laptop, selected range of smart phones and tablets etc. The Internet acts as the common wreath to keep all of these interconnected. Therefore, cloud computing will partially be no better than a dud in absence of the Internet.

Cloud computing has found its popularity owing to a number of its characteristics. The better the user's capability to prune them to one's requirements, the better it shall serve the purposes. Next, the costs of cloud computing have always been claimed of being lowered but actually the overhead changes from infrastructural to operational costs. The reductions still remain on the organizations handling for majorly third party infrastructure are put to use and better management ensures preferable results. The application programming interface is akin to the normal desktop that all the computer users are accustomed to. The cloud computing interface make greater use of the Representational State transfer (REST) based interfaces.

The flexibility of device setting up is surely a very interesting feature for this facility along with multitenancy. This allows the use of the fallow resources and scales up the efficiency of the network at job while on the other hand multitenancy provides ample room for utilization. The functioning at the ultimate capacity is made smooth with the best possible efficiency. Further, with increased options of centralization of resources, the security aspects are well taken care of leaving virtually nothing to leak out of the cycle.

Cloud computing has a fantastic feature of on-demand self-services which require no interference of an IT specialist. The user can install the same on the network of systems without any difficulty. The three cater to different requirements with the first one offering cloud as an infrastructure, the second-cloud as a platform and the third provides a software, which is installed on the user's system for the use of applications and databases with the infrastructure managed by the service provider.

The recent trends have shown that cloud is being opted for by a large number of organizations. This will lead to more variations and choices in the services that are offered in the coming years and that too at extremely competitive tariffs.
