A broker based framework for federated Cloud environment

Every industry is adopting Cloud Computing platform due to its low cost services and zero overheads of maintenance and upgrades. Several new issues are generated because of this wide adoption which are concern to both cloud service provider and cloud service users. Cloud service providers are facing the issue of resource limitations. Cloud service users are facing the issue of vendor lock-in. Federated Cloud through brokering can be used to solve the above mentioned issues. Cloud Federation is the place where cloud service providers can gather to share their resources and the cloud service consumers can buy those resources. The federation is either handled by one of the cloud service provider or a third party known as cloud service broker. The broker is solely responsible for providing services to the cloud consumers which are leased by cloud service providers. In this paper, we are proposing a framework for federated cloud based on the broker.
