Dynamic Resource Arrangement in Cloud Federation

Abstract

Cloud Federation is one of the ideal solutions tothis random burst traffic problem. It focuses on 'borrowing'computing resources from foreign Clouds when home Cloud isabout to overloaded and 'leasing' resources to foreign Cloudswhen home Cloud is free. Considering crucial importance ofbusiness value for a Cloud provider, we need to perform somedynamic, reasonable and simple rules or mechanisms to helpCloud provider making better billing decisions and improvingthe overall performance in a federation scope. Cloud Federationis implemented by network connections, so in common situationthe best candidate Cloud to be federated enjoys a higher speedof connection to the home Cloud. This remains a problem thatseveral Clouds located in a subnet have a high possibility to befederated with each other, thus complicated dependency relationsamong them will appear. In this paper, we have carried out aseries of mechanisms involving dynamic resource arrangement inestablishment and deconstruction of a Cloud Federation, in orderto sort out these dependency relations which are the potentialrisk factors to the overall performance.
