Course Overview:
Salt is the easiest, most powerful way to manage servers. Whether few, hundreds or even thousands of servers, salt can be used to manage them from a single central point. Our objective is to learn Saltstack internals and tricks that can help us flexibly target any subset of servers to run commands and accomplish tasks. We will delve into Salts state system to define the state of the infrastructure in a data-driven way and then enforce that state in seconds. We will look at creating a reactive, self-healing infrastructure using the event system. Saltstack (Salt for short) is open source software developed to automate the configuration of server systems. During this course you will learn how to centrally administer and manage multiple server environments.
