Resource allocation system and resource allocation method in private cloud environment

Abstract

The invention relates to a resource allocation system in a private cloud environment. The system comprises a global policy controller, cloud application policy controllers and group policy controllers, wherein a resource manager interacts with a resource exploring proxy, receives index data, judges whether an alarm is generated for the index data or not according to alarm conditions, and if so, submits the alarm to a policy control network; the group policy controller first processes the alarm, generates a resource adjusting plan if the alarm can be processed, and reports the alarm to the cloud application policy controller if the alarm cannot be processed; the cloud application policy controller processes the received alarm, generates the resource adjusting plan if the alarm can be processed, and reports the alarm to the global policy controller if the alarm cannot be processed; the global policy controller processes the received alarm and generates the resource adjusting plan; the policy control network returns the resource adjusting plan to the resource manager; and the resource manager executes the resource adjusting plan. By constructing graded control policies and assisting coordination mechanisms among the control policies in different grades, the invention effectively improves the utilization rate of private cloud resource.

Description

technical field [0001] The invention relates to the field of resource management in a private cloud environment, in particular to a resource allocation system and a resource allocation method in a private cloud environment. Background technique [0002] Private Cloud, also known as Internal Cloud, refers to an exclusive computing architecture built inside a firewall to provide specific user groups with on-demand computing and storage services. The continuous progress of distributed computing and virtualization technology enables network and data center administrators in enterprises to provide IT infrastructure resources to users in enterprises in the form of services. A private cloud platform usually consists of a virtualized infrastructure platform (based on products such as XEN, KVM, Hyper-V, etc.), and a private cloud manager (based on products such as OpenNebula, Eucalyptus, etc.). [0003] A key step in realizing a private cloud is to use a virtualized infrastructure p...

Problems solved by technology

[0009] Compared with the public cloud, the private cloud environment usually serves multiple sets of business systems in the enterprise, and does not require billing policies. Resource allocation aims to improve the utilization of limited IT infrastructure resources in the enterprise. However, due to the policy server that dominates resource allocation They are independent of each other and cannot effectively coordinate actions, resulting in the timely release of resources by the business system, which often results in a large load on some resources, while some resources are idle and wasted, which cannot achieve the cost-saving effect of the public cloud.

Therefore, the use of existing resource allocation technologies has limited effect on improving the utilization of private cloud resources
