Cloud computing systems provide virtualized resources that can be provisioned on demand basis.Enormous number of cloud providers are offering diverse nu mber of services.The performance of these services is a critical factor for clients to determine the cloud provider that they will choose.However, determining a provider with efficient and effective services is a challenging task.There is a need for an efficient model that help clients to select the best provider based on the performance attributes and measurements.Cloud service ranking is a standard method used to perform this task.It is the process of arranging and classifying several cloud services within the cloud, then compute the relative ranking values of them based on the quality of service required by clients and the features of the cloud services.The objective of th is study is to propose an enhanced performance based ranking model to help users choose the best service they need.The proposed model co mbines the attributes and measurements fro m cloud computing field and the welldefined and established software engineering field.SMICloud Toolkit has been used to test the applicability of the proposed model.The experimentation results of the proposed model were promising.
