• Saltstack Introduction:

　　Salt, a new infrastructure management approach that is easy to deploy, runs in minutes, scales well, and easily manages tens of thousands of servers, fast enough, and second-level communications between servers.

The salt bottom uses a dynamic connection bus that allows it to be used for orchestration, remote execution, configuration management, and so on.

　　A configuration management system that maintains a predefined state of a remote node (for example, to ensure that the specified report is installed and that the specified service is running)

A distributed remote execution system for executing commands and querying data on a remote node (which can be a single node or a node selected by any rule)

The purpose of development is to provide the best solution for remote execution and to make remote execution better, faster, and simpler.

Well, the above is the introduction provided by the Saltstack China User group.

Saltstack------I understand this: Saltstack is a task system capable of solving many specific problems in the underlying environment, and he can quickly and safely communicate with remote systems and perform remote execution and deployment.
