A framework for preserving data security in hybrid cloud environment using trusted multiple cloud service providers

Cloud computing is widely accepted nowadays by the industry as well as academic people as a new generation computing paradigm. Cloud computing has become popular because of its characteristic features like on-demand self-service, ubiquitous network access, resource pooling, rapid elasticity, metered service, etc. But, security challenges are still among the biggest obstacles when considering the adoption of cloud services. Most of the cases, it is seen that the merits of the could computing itself are the root causes of the security issues, and hence it is becoming difficult to tackle. Thus, lots of research activities are happening in the area of cloud computing to make cloud a secure place to keep your sensitive or critical data. This paper proposes a framework for preserving data security in a hybrid cloud environment using trusted multiple cloud service providers. A multi-cloud architecture is used to secure the data of the cloud customer, and the framework uses the trust factor for a dynamic and safe selection of the service providers.
