The only sane and efficient way to manage a large numbers of servers—or even a few dozen, if they change often—is through automation. Automation tools have to be learned and mastered, so they exact a significant up-front cost, but they dramatically reduce the administrative burden in the long run. Perhaps most important, they provide a staunch line of defense against the fatal fat-fingered mistake, which even the most sophisticated cloud operators struggle to avoid.
Ease of use. Configuration management is simple with SaltStack. Because Salt uses the YAML configuration format, states are can be written quickly and easily. YAML state descriptions are structured well, with solid readability. The support for Mako, JSON, Wempy, and Jinja allows developers to extend Salt’s capabilities. The availability of built-in modules makes it easy to configure and manage states.
