Optimized Storage Approaches in Cloud Environment

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(CSP).They are 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 we propose a technique to optimize the usage of cloud storage space .The work in this paper mainly focuses on Deduplication and Compression techniques. Deduplication is a technique used to identifying the redundancy of the data and eliminating the duplication of data there by maintaining only one copy the original data. For optimum utilization of cloud storage the file is compressed after Deduplication before storing into cloud storage. So the bandwidth and time required to transfer file over the network is reduced.
