In the research field Cloud Computing is a booming area due to its plenty of advantages. There are plenty of researches are going on in the field of Cloud Computing like Resource Provisioning, Virtualization, Load Balancing, VM migration, Green Cloud Computing, etc. In the research field Cloud Computing attract the researchers and industrialization person because some area of its not properly explored in terms of performance or effectiveness. Now a days many organization moved on cloud and due to its extensive uses some small cloud providers are running out of the resources. So, Now question is arise how they managed this kind of situation? Hence, Cloud Federation and Inter-Cloud comes into the pictures where multiple cloud providers sell, rent or/and buy resources using formation of cloud or inter cloud communication. Cloud federation is a and inter cloud are the natural evolution of Cloud computing. The main agenda behind in the research field of Cloud Federation is to gain good QoS, cost efficiency, reliability, effective utilization of cloud and achieved excellent performance. In this paper, we are discussing a detailed survey of cloud federation and at the last we have identified open challenges and current trends in the area of Cloud Federation and Inter-Cloud application brokering.
