A Brief Overview of Last Decade in Cloud Computing Essential

In present era, cloud computing is assumed as emerging paradigm in service providing system. Cloud computing demands different type of resources as services for the consumer needs. So, it is a challenge for the cloud computing to provide all resources to the consumers without any delays. But resource availability is finite and it is considered as a serious challenging to deliver the required resources to the consumers on exact time. Resources related to cloud allocated on the fair demands by the consumers and for this reason cloud computing has a challenge to meet the issue of resource allocation. This paper consists of literature review about the resource allocation in the field of cloud computing that explains the issues and solutions of the problems that occur in resource allocation. Moreover, we have explained the methodologies and techniques that are used in the research papers of last ten years and we gave the comparisons of these techniques for better understanding. This paper will help the new researchers of cloud computing for learning different methods about resource allocation.
