A Survey on Cloud Federation Architecture and Challenges

Abstract

Conventional Cloud Computing system possess some limitations. It is difficult for users to switch between various cloud providers due to lack of a standard architecture. There is no standard metering system for cloud computing services. For cloud providers, it is difficult to maintain performance transparency due to changing user requirements, varying loads and limited resources, especially for small and medium providers. Federation of Clouds is the possible solution for these problems. In this paradigm, various cloud providers can federate with each other to expand their business opportunities while achieving optimal resource utilization and cost effectiveness. This collaboration of clouds is fruitful to users in terms of better pricing options, availability of services and overall better Quality of Service. Unlike current Cloud Computing, Federation of Clouds requires a standard architecture to which every participating cloud provider must comply. In nutshell, Federation of Clouds opens a domain of infinite possibilities to reshape the existing world of Cloud Computing and Information Technology, in general. It will provide a level playing field for emerging small and medium level cloud providers to compete among big players. It also has the promise to provide users with better ways to access great computational power and resources.
