Abstract
With the rapid development of the cloud computing technology, it has matured enough for a lot of individuals and organizations to move their work into the cloud. Correspondingly, a variety of cloud services are emerging. It is a key issue to assess the cloud services in order to help the cloud users select the most suitable cloud service and the cloud providers offer this service with the highest quality. The criteria parameters defining the cloud services are complex which lead to cloud service deviation. In this paper, we propose an assessment method of parameters importance in cloud services using rough set theory. The method can effectively compute the importance of cloud services parameters and sort them. On the one hand, the calculation can be used as the credible reference when users choose their appropriate cloud services. On the other hand, it can help cloud service providers to meet user requirements and enhance the user experience. The simulation results show the effectiveness of the method and its relevance in the cloud context.

Summary
Cloud computing has been influencing the IT landscape and becomes an important economic factor [1] due to its mode of operation that is the pay-as-you-go to provide service. Since cloud computing is a minimal barrier to entry and economic scaling, there are a lot of prospective clients to move their business on it. In this context, many small and large cloud service providers emerge every day. Not all of them are the first-hand owners of a cloud infrastructure This means that for those smaller cloud service providers, they are only partnered with a bigger provider which owns the infrastructure. This is not a big problem, even though they are all connected to a bigger infrastructure provider, when it goes down, all “agentmiddleman”
