Cost Effective Selection of Data Center by Proximity-Based Routing Policy for Service Brokering in Cloud Environment
Cloud Services may be offered as public or private or combined. There is the demand of timely, repeatable, and controllable methodologies for evaluation of algorithms, applications, and policies before actual development of cloud products. CloudAnalyst is a tool that helps developers to simulate large-scale Cloud applications with the purpose of understanding performance of such applications under various deployment configurations. CloudAnalyst deploys different service brokering policies depending on the requirements of the cloud application. The service proximity based routing policy used in the simulator selects data center from the earliest region to route the user requests. When there is the situation to select one data center from those with same region, the policy selects data-center randomly without considering cost-effectiveness or other parameters.
