A Proposed Service Broker Policy for Data Center Selection in Cloud Environment With Implementation
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. Using simulation, the authors can study the behavior of them in cloud environment. Cloud-Analyst, the Cloud-Sim based tool, is useful to model and analyze cloud computing environment and applications. The simulator uses different algorithms (Service Broker Algorithms, Load balancing algorithms, etc.) and generates report as per configuration. With the help of simulation report, they can modify the cloud environment as per requirement. The service proximity based routing policy used in the simulator selects data center from the earliest region to route the user requests.
