Profit Based Data Center Service Broker Policy for Cloud Resource Provisioning

Hiring of Cloud resources establishes a business association between Provider and Consumer. In cloud, consumer wants to cut down costs and provider wants to earn more profit even on that cost. Here a symmetric arbitration plan by broker realizes the relationship between buyer and provider. In federated cloud computing environment resources are traded as a commodity and cloud users can migrate between providers without a glitch. This will opens up prospects for brokers to penetrate in the market, acting as mediator between users and providers. Cloud Provider and consumer agree on mutually agreed prices. Still, broker is constantly negotiating providers for optimal or fair costs and provisions the provider’s resources to consumer to earn more profits. Alike financial market brokers, it matches consumer demand with provider’s supply. First this work briefly describes the Cloud Data Center Service brokering and it’s Architecture. Then it surveys Data Center Service Broker policies. The main aim of this work is to suggest and propose a Cloud Brokering Framework that supports all the brokering steps along with proposed ‘profit optimization’ consideration. The framework worked fine as the evaluation shows successful execution of simulation test and the results are promising for the same. The framework reduces the overall cost of running the resources over cloud while complying with Quality of Service (QoS) parameters. This is efficiently done through effective provisioning of DC resources to consumer by broker on the basis of dynamic pricing obtained after negotiating. The framework benefits all parties. The work is simulated using CloudSim based tool. The simulation scenario is carefully generated to show the effectiveness of algorithm. The results are significant in terms of Cost (profit) and Cloudlet execution.
