Description

A solution for both small and large scale systems, Chef is used to streamline and automate configuration and maintenance tasks. Chef is a thin DSL built on top of Ruby, which supports both Linux and Windows. Chef provides enough abstraction to make reasoning about your infrastructure easy.

In this course, you will build a fully functional infrastructure using Chef. This course demonstrates the complete Chef configuration management system and how it can be used for your own environments.

Note: A PC or Mac is required for this course in order to access remote labs.
