Data center active-active system, switching method and device, equipment and medium

Abstract

The invention discloses a data center active-active system, a switching method and device, equipment and a medium. The system comprises a data center A and a data center B. Each data center comprisesa business logic module used for enabling the data center A and the data center B to be active based on clustering deployment and a service bus technology, a data module used for enabling the data center A and the data center B to be active based on a data synchronous bidirectional replication technology of underlying storage and a distributed parallel read-write technology of data, and a link pool configuration module used for enabling the data center A and the data center B to be active based on clustered deployment and mutual backup of clusters of different data centers, wherein according to the link pool configuration modules of the different data centers, based on a polling algorithm, the business logic modules and the data modules of the different data centers are automatically reconnected. According to the active-active system provided by the embodiment of the invention, when any module goes wrong, rapid takeover and switching of the system are realized.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data center active-active system, a switching method, a device, a device, and a medium. Background technique [0002] In the face of sudden disasters, the current information system is very fragile. When an unpredictable sudden disaster such as an earthquake or fire strikes, enterprise data will disappear in an instant. In order to minimize the loss of enterprise data and minimize the loss of danger and disaster, it is necessary to establish a remote disaster recovery system. Usually, the following two solutions can be adopted: [0003] Option 1: For the remote disaster recovery solution, the user establishes two data centers, namely the main data center and the backup data center. Under normal circumstances, the application runs on the computer system of the main data center, and the data is also stored in the storage system of the main data center, and t...

AI Technical Summary

Problems solved by technology

[0007] 1. The utilization rate of equipment is very low. The backup data center only plays the role of data synchronization and can only be used when a disaster occurs;

[0008] 2. The switching time is long, manual decision-making and complicated switching process are required, configuration changes are required, and the backup data center needs to be restarted from the access layer, application layer, and data layer;

[0009] 3. In order to ensure the availability of the backup data center, disaster recovery drills must be carried out regularly;

[0010] 4. Once a disaster occurs in the main data center, it will affect the entire business

[0012] 1. The equipment utilization rate is low. Although the second production center is the dual production center, the two production centers handle different tasks. Therefore, when processing the same task, some equipment still only perform data synchronization;

[0013] 2. The switching time is long, requiring manual decision-making and complicated switching process. After modifying the configuration of the access layer and data layer of the backup data center, all of them need to be restarted;

[0014] 3. In order to ensure the availability of the backup data center, disaster recovery drills must be carried out regularly;

[0015] 4. Once a disaster occurs in the main data center, it will affect nearly half of the business
