Enabling Performance as a Service for a Cloud Storage System

Abstract

One of the main contributions of the paper is that we introduce "performance as a service" as a key component for future cloud storage environments. This is achieved through demonstration of the design and implementation of a multi-tier cloud storage system (CACSS), and the illustration of a linear programming model that helps to predict future data access patterns for efficient data caching management. The proposed caching algorithm aims to leverage the cloud economy by incorporating both potential performance improvement and revenue-gain into the storage systems.
