Security Issues Using Multi Clouds

Cloud computing is one of today‟s most exciting technologies, which involves deployment of various services like software, web services and virtualized infrastructure, as a product on public, private or hybrid clouds on lease basis. Security is considered to be one of the most critical aspects in a cloud computing environment due to the sensitive and important information stored in the cloud for users. The customers face difficult in trading single cloud providers due to risk in service availability and the possibility of malicious insiders. A movement towards "multi-clouds" or in other words, "inter clouds" or "cloud-of-clouds" has emerged recently. Movement towards multi cloud will mitigate the security problem. This paper explains characteristics and the delivery models for cloud computing in short and focuses on the security factors in cloud computing and addresses possible solutions. The paper analyzes the recent research related to the protocols for inter clouds. This work aims to promote the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user.
