Implementation comprises: in the time that user need to apply for redistributing resource or change host, user is chosen and is called a service from service catalogue by user interactions interface, this request is passed to after system management module, through checking, if meet the condition of user's request, cloud service provider will be the resource that user assignment is suitable, then calls configuration tool and prepares running environment for user; User interactions interface, by the interface of access is provided in Web Service mode as all users, obtains user's demand.Service catalogue refers to the service inventory that user can access; System management module is responsible for distributing and managing all available resources; Configuration tool is to prepare running environment for task; Also comprise the supervision statistical module of running status and the resource service condition of surveillance.
Proof procedure comprises: user utilizes RARP to obtain the IP address of host, proposes the application that resource is redistributed by the virtual machine of oneself to host, and host is received after application, holds consultation with administrative center, sees whether the application that user proposes meets SLA;
Meet SLA, host checks whether self has satisfactory resource, has satisfactory resource, by searching the IP address that obtains user's virtual machine used, then to user assignment requested resource; Host does not have to meet user's resource, notifies user;
Do not meet SLA, refusal distributes.
The invention has the beneficial effects as follows:
The scheduling strategy centered by system that the present invention breaks traditions, sets up the schedule policies of customer-centric, and the effective mechanism that provides resource to distribute and manage, can file a request user as required, is very easy to user, has improved resource utilization; Embodied to a certain extent fairness, paid more expense and mean and can obtain more storage and computational resource, user's service request also can preferentially meet with a response.And resource storage in cloud computing can meet maintaining secrecy and more new demand of user completely, these groundworks are all to be completed by service provider, do not need user to worry about, and conveniently save trouble.
Technical scheme of the present invention is the dynamic role by promoting user, set up the scheduling strategy of customer-centric, by resource management and virtual machine (vm) migration technology, user can be filed a request as required, not only facilitated user, and improved the utilance of resource, also embodied to a certain extent fairness, if the expense that user pays is more, just can obtain more storage and computational resource, user's request also can obtain preferential answering.
