HA (High available) High Availability cluster ( two-machine hot standby)1. Understanding: Two servers A and B , when a service, B idle standby, when a service outage, will automatically switch to the B machine to continue to provide services. When the host is back to normal, the data consistency is resolved through the shared storage system by automatically or manually switching to the host as set by the user.2. The software that implements this func
MongoDB cluster technology: replica set sharding, mongodb ClusterA MongoDB replica set is a process of synchronizing data to multiple servers.
