Performance impacts of hybrid cloud storage

Abstract

Cloud storage has seen unprecedented growth in recent times. Consumer electronics contribute significant amount of data to the cloud and as these devices become an inseparable part of our daily lives, it is critical to have insight into the performance impacts of hybrid storage that involves user equipment. In this work, we present performance analysis of hybrid cloud storage assuming multiple scenarios of failure among storage locations. We also present a comparative analysis between multiple existing storage coding techniques based on chunk formation and varying file sizes. We analytically show a composite distribution that caters for retrieval, processing and re-distribution of chunks. Analytical analysis is also presented and compared with simulated results. Results are useful for design of hybrid cloud storage systems.
