Description

Flow control method, device, equipment and storage medium

Technical Field

The embodiment of the invention relates to the field of system disaster recovery, in particular to a flow control method, a flow control device, flow control equipment and a storage medium.

Background

Based on development of cloud computing and k8s related technologies, applications of enterprises are gradually containerized, and the deployment of a single server is changed into cloud deployment. Some enterprises can directly use cloud services provided by large cloud service providers to deploy applications, while some enterprises purchase machines by themselves due to various concerns, and build local private clouds to deploy applications. Disaster tolerance in the current private cloud scene is basically divided into two types, one type is a multi-activity federal cluster, and services are deployed on a plurality of clusters simultaneously and simultaneously provided for the outside; the other scheme is single activity, the cluster roles are divided into a main cluster and a standby cluster, only one cluster provides service to the outside, the other cluster can synchronize data from the main cluster at regular time, and the standby cluster can be started once the main cluster crashes. In the scheme one, because the application is deployed across clusters, the requirements on the application and hardware are relatively high, the application is required to realize high availability of data among different copies, and the delay of network transmission among clusters is required to be extremely small. The hardware aspect of the scheme requires higher construction cost; in terms of software, most of the applications on the market, the open source version does not have a self high-availability scheme, and in order to use the high-availability capability, the commercial version needs to be purchased, so that the cost is high for enterprises. The scheme II mainly relies on the platform capability to realize the data synchronization among clusters, and has lower requirements on the application itself; the requirements on hardware such as network delay are also low. Of course, the requirements on the synchronization capability of the platform are relatively high, different component data are synchronized by using a unified scheme, the real-time performance is not good, and certain data loss exists. Meanwhile, when a disaster occurs, manual intervention is often needed, the north flow is manually switched, and the access flow of the user is guided to the corresponding cluster.
