A QOS Based Optimal and Cost Effective Load Balancing Strategy in Storage Cloud

摘要

The aim of this paper is to create an optimal and cost effective load balancing strategy based on the QOS specified by the user which has been included as SLA in the request sent by the user to the Service provider. Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications. When a user wants to store his or her files in the cloud initially they need to select a cloud service provider to use the providers storage area. Storage cloud belongs to Iaas cloud. We consider the scenario that no VM should be overloaded and at the same time no VM should be idle. For this the data file sent by the user is not stored as a whole file instead it is split into smaller files and distributed among the available VM for storage. This paper mainly focuses on QOS parameters like reliability, stability and the overall throughput.
