The SLA Evaluation Model for Cloud Computing

Cloud Computing is an emerging technology to deliver the infrastructure, network, software, and even the development environment as a service in the philosophy of pay-as-you-use. To guarantee all participants' rights in the cloud, SLA is suggested to be a necessary contract which can protect users and service providers from violation. However, SLA is an early-proposed method that not suitable for new characteristics of cloud computing. This paper present an optimized SLA model for cloud computing and a corresponding evaluation method, which can determine a more fair and reliable evaluation result of cloud service. With this model, users can simplify their selection process, while providers can use the evaluation result for further resource allocation strategy.
