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 o

Example Embodiment

[0085] Example 1

[0086] Such as figure 1 As shown, the method for ensuring high availability of a virtual instance of a power system provided by this embodiment includes the following steps:

[0087] Step 1. Initialize configuration: Enter the server's IPMI management port information, server role information, and communication network information, and establish a basic database based on the entered information to store and manage the configuration cores of all virtual machines and physical machines in the cloud computing environment Associated information, synchronize information when the information changes;

[0088] Step 2. Real-time monitoring of the environment: real-time monitoring of the network and computing status information in the cloud computing environment;

[0089] Step 3. Streaming message communication: the status information collected by the real-time monitoring module is processed and transmitted in the manner of stream messages, the data is cached locally and the ...

Example Embodiment

[0124] Example 2

[0125] Such as figure 2 As shown, the system for ensuring high availability of power system virtual instances provided by this embodiment includes:

[0126] The initial configuration module is used to enter the server’s IPMI management port information, server role information and communication network information, and establish a basic database based on the entered information. The basic database is used to store and manage all virtual machines and physical devices in the cloud computing environment. The configuration of the machine core related information, and the information is synchronized when the information changes;

[0127] The real-time environmental monitoring module is used for real-time monitoring of the network and computing status information in the cloud computing environment;

[0128] The streaming message communication module is used to process and transmit the status information collected by the real-time monitoring module in the manner of stream...

Example Embodiment

[0146] Example 3

[0147] Such as image 3 with 4 As shown, as a specific application combining Embodiment 1 and Embodiment 2, this embodiment provides a system and method for ensuring high availability of a virtual instance of a power system.

[0148] 1. The structure of the guarantee system

[0149] Such as image 3 As shown, in the cloud computing data center environment, when the server hardware failure occurs or is damaged, the guarantee system can automatically detect relevant information, transmit information, and start an automatic judgment mechanism based on the model, and according to the judgment result When migration failure or damage occurs, the automatic migration of virtual instances is initiated; the entire process will effectively ensure the high availability of virtual instances, and further ensure the uninterrupted operation of the front-end access response of the business application system. The cloud computing data center environment includes a network resource ...

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...
