the concept of a replica set
A replica set is a set of servers, one of which is the primary server (primary), used to process client requests, and multiple backup servers (secondary) to hold data replicas of the primary server. If the primary server crashes, the backup server automatically upgrades one of the members to the new primary server.

Fabric is an automated framework for executing programs in batches on multiple machines through SSH. The pre-edited project configuration file can be used to automatically deploy and maintain the project. The entire operation is performed in the local directory, which is very convenient.
Fabric's idea may be based on Capistrano: an automatic deployment framework designed for rails, which has been adopted by many Ruby non-Ruby projects, including Java project
