Cloud Brokerage Model for Resource Pricing and Refund

Digital media content has increased massively due to which, cloud computing is rapidly gaining importance. Cloud computing not only provides ubiquitous access, but also, ease of management of hugely increasing data. The next era is going to be of cloud federation, in which services would be brought up to the user through multiple clouds, creating an Inter-Cloud computing environment. One of the key entities in Inter-Cloud computing is Cloud Broker. Cloud Broker plays an important role in cloud federation environment. Broker has to reserve resources and perform pricing and billing. We have proposed a model for this purpose and presented here, along with its performance evaluation.
