Cloud services have become state of the art of resource sharing and interoperability among different service providers. The federated cloud seek to reduce costs and maximize efficiency, provide flexible and reliable services composed of various external cloud service and internal services, but this would introduce a risk of security due to outsourcing. For organization which provide an integrity cloud service must rely on SLA to illustrate the capacity of risk and performance, the various providers involved in the federations or services compositions should effectively distribute the organizational responsibilities and SLA. To solve the fears and deal with the threats associated with outsourcing, new method for selection of outsourcing cloud service providers(CSP) based on assessment of security and performance is urgently needed. This paper presents an approach on how to select the proper CSP to guarantee organizational SLA, which quantify the SLA terms and calculate a security weight, the organization can choose the appropriate CSP based on security weight, meanwhile minimize the business cost. This paper make contribution on modeling the capacity of the CSP, considering the business cost and historical performance. The proposed approach is validated through case study that shows selected CSP through our approach can best meet the organizational security and cost needs.
