Abstract-In the current generation, developments in cloud computing leads to a tremendous scope for collaborative cloud computing (CCC). In CCC, the resources are universally scattered and distributed across the globe which belong to different organizations and the resources are used to provide services to the clients. Because of the self-governing highlights of elements in CCC, the issues of reputation and resource management must be mutually communicated to guarantee the fruitful development of CCC. These issues are jointly addressed in the past but when we address these two issues jointly, it creates twofold overhead. Hence, resource and reputation management strategies are not well designed and they are not powerful. If the client selects the highest reputation node, then the other reputation nodes are neglected and there is no full utilization of resources and it doesn’t meet client Qos demands. In order to overcome this, we propose a technique called Harmony. Harmony involves three stages: comprehensive resource/reputation management, selection of multi Qos-oriented resource and price-assisted resource and reputation management. Key words: cloud computing, resource management, reputation management and harmon
