Nowadays, due to growth and diversity of possessions (e.g. computers, mobile phones, smart cars, etc.), cloud computing has become popular among people. Users access cloud for different reasons such as searching for information, downloading specific files, and executing remote applications. This designated technology takes advantage of a clustered environment and multi-pathway of communication. This novel field of computation requires a wise decision-maker on its pathway in which trust and reputation are two major issues on it. Moving data computing into "Cloud" presents several security issues for main structure, but it will be also much more convenient for users and customers in the way of their utilizations. Therefore, it would be required to turn cloud system into precision mode, more than ever. The action of dispatching jobs on nodes increase the vulnerability to attack through the non-estimated trustworthiness among nodes.In this paper we propose a novel effective model for cloud job distribution to have better decisions in its job switching and rescaling a hierarchical construction for security management and dynamic control in the area where nodes are categorized within. Our proposed system is based on job replica output for consistency and higher monitoring on dispatcher; thus, with grouping new sections, including trust on node, trust on region, and hierarchical trust on dispatcher. Dispatcher would be able evaluate the current trust through several factors, such as satisfaction, reputation, and history of success. And finally choosing the conducive service provider and switch the job along.
