Nowadays the number of people that outsource their data to the cloud increases dramatically. Cloud computing offer cost-effective dynamic, scalable and shared services for enterprises from remote data centre. However, the problem of trusting cloud computing is a paramount concern for most enterprises in such a way that trust is widely regarded as one of the top obstacles for the adoption and growth of cloud computing. There are a lot of methods proposed by researchers to help the consumers identify the cloud service provider who seems to be more reliable. These trust-aided unified evaluation framework help in measuring the trustworthiness of cloud service providers. This work provides a generic analytical framework to compare different trust models based on a set of assessment criteria to help cloud consumers find the trust model that best satisfies their trust concerns in cloud computing.
