Abstract: Business locked into cloud doesn’t guarantee that the provision of service quality will be continued. By considering the above problem there is a need for the business to permanently caring the cloud that is used and switching to another cloud if problems are discovered. Currently migrating to another cloud is not ignorable. Services like EC2 and S3 are incompatible and doesn’t follow specific standards but follow their own. For complicating still more many companies not only build on public on Public Clouds but their own Private Clouds will be combined with public cloud, evolving to the hybrid cloud. The concept of Meta Cloud is introduced that includes runtime and design time components. This Meta Cloud minimizes the technical incompatibilities and thus switching to another cloud. This helps the customers to choose appropriate cloud services for particular appropriate use case.
