Abstract: Cloud service users (CSU) subscribe services from a specific cloud service provider (CSP). Several cloud service providers may offer the same as well as different services. Hence various factors have to be considered while selecting a CSP which offers the same type of services. An intelligent third party (ITP) helps the CSU in choosing a best suited CSP by capturing the requirements from CSU using fuzzy logics. These are matched with service offerings of the CSPs using multi criteria decision making process called the analytic hierarchy process (AHP) and the best suited CSPs are suggested by ITP among the registered CSPs to the CSU. A negotiation process follows where the CSU can make their choice in choosing the suggested CSPs. A partial SLA is generated between the CSU and preferred CSP defining the various services selected attributes provided by the CSP, other requirements of CSU and violation details.

Keywords: cloud service provider; CSP; service level agreement; fuzzy logic; decision support system; analytic hierarchy process; AHP; intelligent third party; ITP.
