Data Security in Single and Multi Cloud Storage–An Overview

Abstract

In the modern era of computing, Cloud computing will play a major role in the Internet of Services. Although many cloud service models are there, Infrastructure as a Service (IAAS) has become the foundation of the future Internet of Services (IoS). Many advantages of cloud computing attracts the individuals and organization to move their data from remote to cloud servers. Cloud Providers mainly focus on delivering services and provides a lesser focus in data security and privacy which is the main aspect in cloud computing. Since the single cloud storage does not fulfil the demands of the individuals and organizations, a move towards multi-cloud storage has been emerged. This report offers an overview of motivation of attackers, various techniques and its limitations made to protect information security in single and multi-cloud storage. In addition, this paper also explains the common challenges in adopting single and multi-cloud storage services. This work provides a better solution in designing multicloud architecture and key consideration in decision making process for the individuals and organizations in the adoption of better cloud storage service.
