Abstract

The collaborative cloud computing (CCC) which is collaboratively supported by various organizations (Google AppEngine, Amazon’s EC2, IBM’s Blue-Cloud, Microsoft’s Azure) offers a promising future for distributed cloud resources. Trust and security have prevented businesses from fully accepting cloud platforms. To provide trustworthiness between clouds, providers must first secure virtualized data center resources, sustain user privacy, and preserve data integrity. This paper suggests using a trust-overlay network over multiple data centers to implement an integrated resource and reputation management system for establishing trust between service providers and data owners. Therefore, we propose a platform called Harmony which incorporates key technological innovations by enhancing the efficiency and effectiveness of resource and reputation management to meet user’s diverse Qos demands.
