Description
Technical Field
The present application relates to the field of dual hot standby technologies, and in particular, to a dual hot standby switching method, a dual hot standby switching system, a site device, and a computer readable storage medium.
Background
Dual hot standby (Dual-Machine Hot Standby) is a high availability architecture in which there are two servers (one primary and one secondary), the primary server handles the actual workload, and the secondary server is on standby ready to take over the functions of the primary server. In a dual hot standby architecture, data synchronization is maintained between the primary and standby servers to ensure that data on the standby servers remains consistent with the primary server. Common data synchronization methods include replication-based techniques such as database replication or file synchronization. When the main server fails or is not available, the standby server immediately takes over the roles of the standby server and continues to process the user requests and tasks. This handoff process is typically automatic and needs to be done as quickly as possible to reduce system downtime and the impact of the user experience. The dual hot-standby architecture provides high availability and fault recovery capability so that the system can continue to operate properly even if a hardware fault, software error, or other unexpected situation occurs. It can be applied to various critical business systems such as database servers, web servers, application servers, etc. to ensure continuity and availability of the system.
However, in the event of a failure of the primary server, the secondary server needs to take over its work. The time of the failover depends on a number of factors, including detection time, resource preparation time, service start time, and the like. If the failover time is too long, it may result in delays or interruptions in user requests. In addition, under normal conditions, the standby server is in a standby state, and its computing and storage resources are not fully utilized. This may result in lower resource utilization and increased system costs.
Therefore, the problem that the fault detection of the main server is not timely and the utilization rate of the standby server is low exists in the existing dual-machine hot standby, and a method for timely detecting the potential fault of the main server and fully utilizing the standby server is needed.
