Implementation of Raaes: Reliability-Assured and Availability-Enhanced Storage System

Abstract

Cloud computing is clutching and tantalizing the world and taking the distributed computing archetype into different dimensions with different names in recent decades. In today’s scenario, 99 percent of the organizations and even the common people are migrating to adopt storage services on cloud for their business and personal usages because of its attractive and beneficial features with less maintenance. The most popular service providers like Google, amazon, Yahoo, and Microsoft are increasing their users to millions in every moment because of their attractive and promoting mechanisms. But, at the same time, their services are hosted from different data centers that contain thousands of servers, as well as power delivery (and backup) and networking infrastructures. In this scenario, when users demand high availability and low response times, each service is mirrored by multiple data centers that are geographically distributed. This may leads the high cost for maintenance and some challenges to provide integrity and consistency. So, the predecessor of this research work investigated the issues in   Providers’ and user’ perspective to provide cost-effective optimized cloud storage while meeting the reliability and availability requirement throughout the whole Cloud storage process. And also, the research has proposed the RAAES framework to optimize and to provide efficient cloud Storage in order to significantly reduce the occupied space and cost jointly with meeting the reliability assurance requirements. Thus, through this paper this research has been proven that it could ultimately reduce the request-response time delay while enhancing the availability requirements by implementing the RAAES, hence it has a positive effect on promoting the development of Cloud by an efficient Storage.
