Cloud computing has changed the IT industry ever since it evolved. Cloud computing is basically cost effective and on demand service offered to the clients. The resources in the cloud are rented according to the needs and budget of the client. As the cloud has involvement of many parties and resources its security remains a major issue. Cloud Computing is still not able to reach its true potential due to limitations in security offered in the cloud. In the present scenario, there is dependency on more than one cloud i.e. organizations use services from multiple clouds. This leads to a multi-cloud or cloud-of-clouds environment.
