K-Nearest-Neighbor-Based Service Broker Policy for Data Center Selection in Cloud Computing Environment

Cloud Computing offers various resources as servicesto the internet users. This arise a very important issue in selectingthe appropriate data center(s) to serve users' requests. One of theimportant components in the cloud computing environment is theservice broker, which's responsible for selecting an adequate datacenter to serve a user request. Many of broker policies areimplemented in the cloud computing environment. AK-Nearest-Neighbor-Based service broker policy for data centerselection in the cloud computing environment is proposed in thispaper. This policy used a list of distinctive features andcharacteristics for each data center and user's request. Theresults show that the proposed policy outperformed therandom-based policy in terms of Average Response Time (ART)and Average Processing Time (APT)
