Decentralized meta-brokers for inter-cloud: Modeling brokering coordinators for interoperable resource management

The management of internal resources in large-scale environments is a crucial challenge due to the large number of users and service requests. In clouds, an efficient resource manager orchestrates internal resources by assigning brokers to users for acting on behalf of their clients. This is to map user requests to cloud datacenters for service allocation and execution. However, as cloud computing matures, it is crucial to enable the concept of inter-clouds, that is to say, enabling the collaboration and thus, the interoperation between several disperse (and highly likely heterogeneous) clouds. To this extend, we introduce the meta-broker concept for inter-cloud settings by modeling its conception in a total decentralized fashion. This is to coordinate different clouds brokers for establishing a reactive cross-exchange and service automation while offering transparency to users. We simulate an inter-cloud for measuring the performance of the average execution time for various users that submit concurrently a massive amount of services. The results show effective performance levels when operating under meta-brokering solution.
