Cloud computing is an evolving paradigm, as the NIST defines cloud computing is the internet based computing where the shared servers virtually provides service, software, infrastructure, platform, and other devices and resources and hosting to the customers on a Pay – as – you – use basis. It also enables the convenient, on – demand network access to a shared pool of configuration enable computing resources. Cloud computing appears as a computational paradigm as well as a distributed architecture, and its main objective is to provide secure as well as quick computing service to the consumers. The cloud enhances the agility, scalability, ability to adapt the adequate number of users according to the demand cost reduction using the optimized and efficient computing. In this paper, we surveyed the various routing algorithms that are used for the cloud computing processes, the optimal resource allocation techniques used in cloud computing and its applications in various fields. Cloud computing is widely used in distributed and mobile computing environment. This is possible due to miniaturization of communication technology. The significance of the routing is considered as an important part in the cloud computing since they are based on the on – demand networks. Hence allocating the nearest route is a vital role in cloud computing.
