Cloud computing is a set of processes in which a large group of remote servers communicating together so as to allow sharing data-processing tasks, data storage and online access to compute resources. Managing the drastically increasing number of requests presents the most challenging part of cloud computing. This paper discusses a novel hierarchy for optimizing load to achieve a high user satisfaction. By preserving data about the best cloud service providers, this hierarchy enhances the end user's satisfaction. In other words, as it is proposed in this hierarchy, suppliers with a maximum number of satisfied requests are more likely to be selected as soon as they have available resources/services. On the other hand, when no provider is capable to accomplish the requested tasks, a possibility of cooperation between two or more cloud suppliers is presented as a second option to ensure 100% of user's satisfaction. In order to apply such an approach, a huge amount of resources are wasted when the in-between communication is taking place. Therefore, an optimized method of SLA contract establishment is tackled in this paper.
