The cloud computing is a technology using internet and remote servers the users can run and deploy their applications. Different services are provided by Cloud Service Providers (CSPs).They is software-as a service, plat-form-as-a-service, infra-structure-as-a-service, etc. Storage as a service is also provided by CSP to back up the users data in to cloud .The storage service provided by the CSP is cost effective, reliable. These services are called "Pay-as-you-go". That is depending on the usage of service consumer is charged. So for maximum utilization of cloud storage optimization is a task. In this paper, they propose a technique to optimize the usage of cloud storage space.
