Performance Evaluation of Virtual Machines using Service Broker Policies in Cloud Computing

Resource sharing is the base rule governing the IT Business. Cloud Computing is a paradigm for delivery of computing resources i. e. hardware and software over the internet. Cloud Computing enable individuals as well as business to use software and hardware as a service that are managed by third parties (Cloud vendors) at remote locations. This paper discussed the three cloud service broker policies for selecting the appropriate data centers in cloud environment. Because there is forever been the necessity to pick out applicable datacenter so additional tasks for processing the request ought to be dispensed efficiently in least interval, therefore the issue of choosing appropriate datacenter that is thought as service broker policy is quite necessary. To simulate large scale cloud applications Cloud Analyst, the Cloud Sim based GUI tool is used. It produces the results in form of tables and graphs. We can simulate our scenario using Cloud Analyst to evaluate the number of VMs required for processing, data centers for storage and management of user requests and also the load on the cloud.
