Advance resource reservation and QoS based refunding in cloud federation
Mohammad Aazam, Eui‐Nam Huh · 2014
With rapidly increasing digital media, importance of cloud computing is also scaling up. Cloud computing not only provides ubiquitous access, but also, ease of management for 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. At times, promised quality cannot be delivered. When a customer gives up the service without completely consuming it, service provider has to consider quality degradation factor, while refunding the remaining amount. We have proposed a model which addresses the issue of advanced resource allocation and quality of service (QoS) based refund. We have implemented and tested our model on CloudSim 3.0.3 toolkit. The results presented here justify and endorse our model.
