Cloud computing provides distributed computing resources such as servers, storage and applications to the end users through data centers. The data centers are geographically located at different locations. The client applications or requests being serviced by cloud service providers on “pay per use”. So, different pricing models are adapted to compute the cost and revenue of the data centers. The cost of VM is computed depending on its placement in the data centers through broker policies. So, the broker policies have a significant role in evaluating the cost of the VM which directly impacts on revenue of the service provider. In the computing competition, the VM cost should be minimized by which service demand will be maximized. Moreover, the response time and processing time of the data centers need to be minimized to posses commendatory Quality of Service. In this work, we propose a new service broker policy to minimize the total cost. The total cost considers the VM cost and the data transfer cost. The proposed mechanism also reduces the response time and data processing time of the data centers. The proposed policy is simulated in Cloud Analyst. We examine the performance of the proposed mechanism with ten different scenarios. Finally, we compare performance results with respect to VM cost, data transfer cost, total cost, processing time and response time of data centers with the existing policies and observe better than these.

IaaS云模型中用于数据中心分配的经济高效的服务代理策略

云计算通过数据中心向最终用户提供分布式计算资源,例如服务器,存储和应用程序。数据中心在地理位置上位于不同的位置。云服务提供商按“按使用付费”服务客户端应用程序或请求。因此,可以采用不同的定价模型来计算数据中心的成本和收入。VM的成本是根据其通过代理策略在数据中心中的位置来计算的。因此,代理策略在评估VM成本方面起着重要作用,而VM成本直接影响服务提供商的收入。在计算竞争中,VM成本应降至最低,从而使服务需求最大化。此外,数据中心的响应时间和处理时间需要最小化,以达到可称赞的服务质量。在这项工作中,我们提出了一项新的服务经纪商政策,以最大程度地降低总成本。总成本考虑了VM成本和数据传输成本。所提出的机制还减少了数据中心的响应时间和数据处理时间。提议的策略在Cloud Analyst中进行了模拟。我们在十种不同情况下研究了所提出机制的性能。最后,我们将与虚拟机成本,数据传输成本,总成本,数据中心的处理时间和响应时间等性能结果与现有策略进行比较,并观察到比这些更好的结果。总成本考虑了VM成本和数据传输成本。所提出的机制还减少了数据中心的响应时间和数据处理时间。提议的策略在Cloud Analyst中进行了模拟。我们在十种不同情况下研究了所提出机制的性能。最后,我们将与虚拟机成本,数据传输成本,总成本,数据中心的处理时间和响应时间等性能结果与现有策略进行比较,并观察到比这些更好的结果。总成本考虑了VM成本和数据传输成本。所提出的机制还减少了数据中心的响应时间和数据处理时间。提议的策略在Cloud Analyst中进行了模拟。我们在十种不同情况下研究了所提出机制的性能。最后,我们将与虚拟机成本,数据传输成本,总成本,数据中心的处理时间和响应时间等性能结果与现有策略进行比较,并观察到比这些更好的结果。
