Cloud Computing, storage, processors, memory, etc. It is a special form of distributed computing, where resources are completely abstracted from the consumer. The number of Cloud Service Providers (CSPs) that offer the computer as a service has recently increased and many customers need to interact with unknown service providers to perform transactions. In such open and confidential environments, trust helps to improve consumer confidence and provides a reliable environment for them [8]. A trust-based ranking system can help them choose between services according to their needs. In this research, multi-criteria decision making methods (AHP, ANP, TOPSIS, ELECTRE, PROMETHEE and VIKOR) were used make rating for the providers according to their infrastructure parameters. Then a comparison algorithm invented to compare the methods ranking results. According to our case and used methods "Rackspace" provider was the most agreeable one between the others.
