Guarantee method and system for high availability of virtual instance of electric power system

Abstract

The invention discloses a guarantee method and system for high availability of a virtual instance of an electric power system. The method comprises the following steps of step 1.initial configuration;step 2.real-time environment monitoring; step 3.streaming message communication; step 4.quintuple model analysis and judgment; and step 5.virtual instance migration. The system comprises an initial configuration module, a real-time environment monitoring module, a streaming message communication module, a quintuple model analysis and judgment module and a virtual instance migration module. According to the method and the system, the continuous operation of front-end access of an application system in a cloud environment is guaranteed; the system can scan actively; when a fault of a physical device is discovered, the system analyzes according to a quintuple model and judges whether the fault makes a fatal impact on the system operation; and when the system judges that the fault can affectthe operation of the virtual instance of the application system, the system starts a virtual machine migration and recovery mechanism, so that the continuous front-end access of the virtual instance of business is guaranteed.

Description

technical field [0001] The invention relates to a high-availability guarantee method and system for a virtual instance of a power system under a server failure, and belongs to the technical field of power system cloud data processing. Background technique [0002] With the gradual start of the "Thirteenth Five-Year Plan" task in the power industry, cloud computing platforms for power companies at all levels have been gradually established. According to the country's advocacy, more and more cloud platforms have adopted open source technology and self-developed ideas. Due to the particularity of the power industry, security has always been the top priority in the process of informatization construction. In particular, some core businesses have high requirements for the uninterrupted operation of the system, and there is almost zero tolerance for system downtime. The high-availability mechanism of the system can ensure the uninterrupted operation of the system when the hardwar...

AI Technical Summary

Problems solved by technology

[0004] (1) Low degree of automation in physical fault discovery and judgment

[0005] At present, the discovery of physical faults relies on manual or decentralized monitoring platforms, and there is no unified hardware fault discovery management for cloud computing environments; even when hardware faults occur, there is no complete basis for judgment, and the fault can be clearly analyzed The impact on the virtual machine that carries the business system on the cloud platform, such as whether hard disk failure or network failure will cause a catastrophic event, and whether virtual machine migration or recovery is required often depends on manual experience

[0006] (2) Lack of effective virtual machine automatic migration and recovery mechanism

[0007] When a fault occurs, there is no effective and automatic virtual machine migration and recovery mechanism; or relying on the functions of commercial software such as VMware, when using open source virtualization such as KVM, it is often necessary to manually carry out according to experience and operation manuals Step-by-step operation; due to the difference in human capacity and operation delay, it is often impossible to guarantee the uninterrupted operation of the business carried by the virtual machine, causing certain hidden dangers to the business stability

[0008] To sum up, the existing open source virtualization technology has the problem of low availability of virtual instances, which cannot guarantee the uninterrupted operation of services carried by virtual machines
