A Review on Cloud Data Storage in Virtual Perspective

Abstract — CLOUD can be expanded as Common Location independent On-line Utility that is available on Demand. This review starts with study on cloud computing in virtual perspective. The cloud has many "on-demand " service models, of which, cloud storage is a model which is amorphous today and with neither a clearly defined set of capabilities nor any single architecture. This paper carefully studies on taxonomy of storage virtualization which forms the basis for cloud storage. The review on, CDMI and OCCI interface and their integration in cloud storage referential model helps researcher to implement Information Life-cycle Management (ILM) through tiered storage to store the backups. The cloud data can be retrieved through n-tier and those tiers are useful to allocate future storage requirement. This review concludes with challenges to be eschewed in cloud storage. To sum-up, this review will be a compendium for the researcher, to understand cloud data storage in virtual perspective
