Abstract:

Cloud Computing has emerged as a paradigm to deliver on demand resources such as infrastructure and applications to customers as per their requirements on a subscription basis. Due to an exponential increase in the number of service providers, customers need a basis to make a judicious choice of a cloud offering. Thus to assist customers in selecting a most trustworthy cloud provider, a unified trust evaluation framework is needed. In this paper, a hierarchical trust model has been proposed to rate the service providers and their various plans for infrastructure as a service. Such a trust ranking mechanism will help the consumers to compare and rank alternative service providers based on their requirements.
