Lastly, we discuss how to move such a multi-cloud environment for- ward by integrating clouds managed by the community or are offered as public clouds. Furthermore, we discuss implications and solutions for a unified metrics system assisting the users to find and utilize resources appropriate for their applications. We have practically demonstrated its use as part of a Future- Grid service, allowing users of FutureGrid to utilize such a service. It can be run by individual users or offered as a service to a shared user community. We present the design of a toolkit that can be employed by users and administrators to manage virtual machines on multi-cloud environments. We conclude by discussing on future directions and trends towards the holistic approach in this regard.

All these aspects require a comprehensive review of the state of the art, including ongoing projects and studies in the area. The spectrum of challenges and obstacles that the Inter-Cloud realization is faced with are covered, a taxonomy of them is provided and fitting enablers that tackle each challenge are identified. Furthermore, it categorizes and identifies possible Cloud interoperability scenarios and architectures. This survey initially discusses all the relevant aspects motivating Cloud interoperability. However, Cloud vendors have not taken into account Cloud interoperability issues and each Cloud comes with its own solution and interfaces for services. Recent studies show the benefits in utilizing multiple Clouds and present attempts for the realization of Inter-Cloud or federated Cloud environment. Similarly, interconnected Clouds, also called Inter-Cloud, can be viewed as a natural evolution of Cloud computing. A brief review of the Internet history reveals the fact that the Internet evolved after the formation of primarily independent networks.
