A Survey on Resource Provisioning in Cloud

Cloud Computing allow the users to efficiently and dynamically provision computing resource to meet their IT needs. Companies are able to rent resources from cloud for storage and other computational purposes so that their infrastructure cost can be reduced. Further they can make use of company-wide access to applications based on pay-as-you-go model. Hence there is no need for getting licenses for individual products. However one of the major pitfalls in cloud computing is related to optimizing the resources being allocated. Resource allocation is performed with the objective of minimizing the costs associated with it. The other challenges in resource allocation are meeting customer demands and application requirements. In this paper we have presented a widespread survey on various resource allocation strategies and their challenges are discussed in detail.
