The Implementation And Test Of Tenant Management Based On Secondary Development Of Resource Orchestrator

With the rapid development of cloud computing technology, most IT vendors do the transition to cloud computing.With broad utilization of Infrastructure as a Service, the cost of building a cluster of infrastructure largely decreases and the utilization of infrastructure resources obviously increases. Under this background, Fujitsu launched a rapid deployment solution of cloud computing:EasyCloud. EasyCloud is a platform of cloud computing helping users to rapidly deploy the environments of cloud computing. It is based on server and storage of Fujitsu's, with the technology of virtualization and Resource Orchestrator which is a core component of resource management of Fujitsu's cloud computing. ROR is a software which can design and manage infrastructure automatically, providing security for multi-tenant environment of private cloud.As the ROR put into use,new requirements constantly coming out which pushes Fujitsu to do the secondary development. In order to have better compatibility and usability, the main function of secondary development of ROR is compound certification, role customized, code transfer from J2EE to JavaEE.The main work of this thesis includes:(1)Based on the understanding of the original code, this secondary development using some techniques such as multi-tenant technology, SSO and LDAP authentication technology, EJB technology, RESTFUL technology, Mock technology etc These technologies also need to be study to make better understanding of ROR.(2)lt uses relevant technologies to do the secondary development of ROR, including requirements analysis, general design, detal design, implementation and unit test.The essence of this thesis is function extending and to make ROR meet users' demand and adapt market's needs better.
