A Selection Strategy Supporting Service Outsourcing in Cloud Platform

As a natural evolution of Services Computing, Cloud Computing has provided a promising way, for delivering flexible and cheap computing resources, via cloud platform. However, the computing resources held by a cloud platform are usually limited, compared with the nearly unlimited resource requirements from various end users. In this situation, seeking for the appropriate computing resources from the outer cloud platform, i.e., outsourced resources, has become a promising remedy for cloud platform with limited computing resources. While the outsourced resources are usually of diverse sources, various service quality levels, and different structures, which bring a big challenge for the selection of outsourced resources. In view of this challenge, a selection strategy, named OS34CP (Outsourced Service Selection Strategy for Cloud Platform, OS34CP), is provided to help the service outsourcing process, in cloud platform. Finally, related work and comparison analysis are also made, to demonstrate the advantages of OS34CP, for dealing with the service outsourcing problem in cloud platform.
