The load of S3, statistical monitoring module monitors virtual resource also by resource management module according to access strategy, determines whether as user distributes sub-virtual resource;
The load of S4, statistical monitoring module Real-Time Monitoring virtual resource also passes through resource management module at least according to the interrupt strategy in step S2, the sub-virtual resource shared by releasing user, and does synchronized update configuration to residue virtual resource.
Coordinate with reference to shown in Fig. 2 and Fig. 3, concrete, in user environment, user can pass through exercisable client device, such as PC, mobile internet device, access request is initiated through step S101 to user management module 10 by API (ApplicationProgrammingInterface, application programming interface).User management module 10 receives and the access request of verified users 100.
Concrete, this user management module 10 performs step S102, to judge that whether the user of this initiation access request is for registered user.If so, then redirect performs step S104 and judges whether the mirror snapshot corresponding with the access request of user further; If not, then redirect execution step S103 carries out new user's registration.This user management module 10 receives and preserves the application for registration of user, and generates unique user identification code for user.
For new user, the log-on message of user is sent to policy issue module 30 by user management module 10, and is that user generates access strategy and interrupt strategy and is sent to resource management module 20 by policy issue module 30 according to the log-on message of user and access request.
Wherein, the access strategy in described step S2 comprises: to the grade classification of access privilege, in order to arrange the access rights of different brackets to different user; Interrupt strategy in described step S2 comprises: to the division of user's antithetical phrase virtual resource 601,602,603 holding time length, the grade classification of user's antithetical phrase virtual resource 601,602,603 consumption, and user publishes operation.
As shown in Figure 3, in the present embodiment, cloud computing operator comprises to the virtual resource 60 that all users can provide and being distributed by resource management module 20 and sub-virtual resource 601, sub-virtual resource 602 and sub-virtual resource 603 shared by user A, user B and user C.Wherein, the different area shown in sub-virtual resource 601,602,603 represents virtual computing resource, virtual storage resource, virtual network resource and the virtual software resource that different sub-virtual resources is formed.
