Dynamic Resource Allocation Mechanism Using SLA in Cloud Computing

Resource provisioning is greatly required to expand the performance in cloud. The hardware technique used for resource allocation methods can be central processing unit (CPU) scaling, which is the frequency of physical cores. The software technique used can be horizontal and vertical elasticity. The resource management affects the evaluation of a system by performance, functionality, and cost. The resource management in cloud environment should have enormous policies and decisions for adhering various objective optimization. Efficient resource management is the process of allocating the resources and handling the workload variations effectively. The computing resources have to be handled efficiently among the users of virtual machines. Service level agreement (SLA) is defined as the contract made between the providers and the customers of cloud for guaranteeing the quality of service (QoS) issues. This paper gives various policies defined in cloud computing related to SLA issues.
