Measuring effectiveness of TBRP method for different capacity Data centers

Abstract Cloud computing refers to applications and services that run on a distributed network using virtualized resources and accessed through web as utility. Resource provisioning, policies allow efficient sharing of resources available in a data center, and these policies help to evaluate and enhance the cloud performance. Resource provisioning that maintains the quality of service with best resource utilization is a challenge. The template based resource provisioning and utilization method (TBRP) overcomes the problem of over-provisioning and under-provisioning of resources by designing appropriate templates with QoS parameters which avoid SLA violations. The results show that in TBRP method one need to design variable template for better performance and use depending upon the capacity of Data-Center.
