摘要：Cloud Computing is a paradigm to provide the services like Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Virtualization technology plays an important role to provide these services. Due to lack of finance as well as requirement, data center providers are unable to establish data centers all over the world. To provide better Quality of Service (QoS) and maintain Service Level Agreement (SLA), data center providers collaborate with other data center which is named as a Federated Cloud. Load balancing process distributes the load or service request among the data centers by implementing distribution policies. Depending on the policies, the central manager chooses the location to deploy the virtual machine. This paper proposes the data center selection algorithm in a federated cloud to optimize the cost as well to improve the performance.
