摘要：Cloud computing provides an exclusively latest model for enterprise computing since it switches a fixed-cost infrastructure into a new prototype based on utility-oriented services on the subscription basis. Distributed resources and services that belong to different organizations or sites can be shared among the users who significantly reduce the need for investment in computing resources by the organizations. Success of cloud storage providers can present a considerable risk to customers, as it becomes exceptionally expensive to change storage providers. Dealing with “single cloud” providers is less popular due to risks of reliability, failure, service availability and security of data stored. Contrarily, multi-cloud, improves the availability, integrity and confidentiality of information stored in the cloud through encryption, encoding and replication of the data on diverse clouds. Multi-clouds improve the perceived data availability and, in most cases, reduce the access latency significantly, when compared with cloud providers individually. We explored that there has been very little attention devoted by the research community on security and privacy issues of multi cloud providers than with the use of single clouds. This paper is aimed at surveying privacy and security issues of single and multi-cloud and suggests promoting the use of multi-clouds due to minimized security risks that affects the cloud computing user.
