Cross-regional disaster recovery method and device

Abstract

The invention discloses a cross-regional disaster recovery method and device. The method comprises the following steps of respectively deploying cloud networks in two partitions, wherein each of the two cloud networks is provided with a computing resource layer, a database layer and a storage layer; and respectively carrying out monitoring and disaster recovery on the computing resource layer, thedatabase layer and the storage layer. According to the method and the device, the cross-regional disaster recovery of hierarchical management is realized through the cloud network, the deployment cost is low, the switching time is short, no negative influence is generated on services, and the time for cross-regional disaster recovery can be shortened. Furthermore, cross-regional disaster recoveryis achieved on the computing resource layer, the database layer and the storage layer respectively, so that a complete cloud disaster recovery scheme is achieved, and a problem of local disaster recovery and even remote disaster recovery of the important and core-level services and above is solved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a cross-region disaster recovery method and device. Background technique [0002] At present, Internet core and important services are often deployed in multiple regions, and business disaster recovery is carried out. For example, core-level services need remote disaster recovery, and important-level services need intra-city disaster recovery. In case of failure, DNS (DomainName System, domain name system) switchover to complete the failover. [0003] A typical Internet business disaster recovery solution not only undertakes the task of business disaster recovery, but also undertakes the task of load balancing and performance optimization in many cases. Several common disaster recovery modes are: [0004] 1) Disaster recovery method of master and backup images. The deployment of the two data centers is exactly the same, and each website release must be released in the two...

Problems solved by technology

[0009] 1) Most of the traditional disaster recovery schemes adopt the cold standby method, resulting in high construction costs and low investment benefit ratio, and often require long-term commissioning and preparation due to various problems when switching between the active and standby systems. For real-time fault migration, will cause business interruption

[0010] 2) Traditional disaster recovery solutions require a long period of time in the process of cross-regional disaster recovery. Cloud disaster recovery can effectively shorten the time. However, there is currently a lack of perfect solutions for cloud computing, database, and storage disaster recovery, and the existing cloud Disaster recovery solutions are limited to intra-city disaster recovery, and often rely on third-party storage to achieve overall disaster recovery. For unified storage solutions, such as the Ceph storage solution widely used in the cloud, it is required to be implemented based on the same storage cluster. Regional disaster recovery and long-distance intra-city disaster recovery are difficult to meet
