Enterprise Integration And Management Of Distributed Computing Resources

With the increasing number of distributed computing resources within an enterprise, how to manage these distributed resources has become a crucial factor to reduce administration costs of the enterprise. Most contemporary resource management models are designed on business logic, which results in a lot of couplings between the resource management policies and the business logic. Therefore, when the business logic changes, the resource management policies need to be changed accordingly. To solve this problem, a scalable resource management model that is independent of business logic is required, which also needs to be able to adapt to changing business needs.In light of the requirements above, this thesis introduces a distributed resource management model that is separated from business logic and realizes an independent resource management layer. This model has a layered and modularized architecture, with specialized modules responsible for the management of distributed physical resources, the mapping relationship from physical resources to logical resources and the distribution policies of these logical resources. In this model, the differences between distributed physical resources are effectively hided to the business applications and a set of interfaces with the outside applications are provided so that the resource management mechanisms are transparent to the upper level business logic. In this thesis, the general picture of the whole system and the organizations of components are given first, then the functions and core technology of the key components are described in detail, including the organization of logical resources and distribution policies. Since my major mission in this project is to design and implement the logical resource distribution policy, this thesis focuses on the resource distribution policies and analyses the theoretical model the policies are based on and how each sub policy, including ownership policy, share policy, borrow/lend policy and reclaim mechanism, is designed. To verify the correctness of the policies, a command-line tool is implemented , we simulate resource allocation requests from customers and compare the output results with the theoretical calculations. The test results show that the system introduced in this thesis could accomplish the organization and administration of distributed computing resources. After further improvements, it could provide an effective solution to the resource management problem within an enterprise.
