About this Course

The configuration management and data center automation tool that streamlines every step of IT service delivery, Puppet allows you to provision physical and virtual machines, orchestrate configuration management and develop, test and deploy code faster. Designed to easily automate repetitive and error-prone system administration tasks, Puppet's declarative language allows you to state how your systems should be configured to do their jobs. It's easy to quickly set up systems in a reliable and repeatable way.

This course demonstrates the complete Puppet configuration management system, and how it can be used to build and scale reliable infrastructure for your own environments. As a continuous hands-on lab intensive course, students will build a fully functional infrastructure using Puppet. By the end of this course you will have a solid understanding and hands-on experience with Puppet, and the knowledge to integrate Puppet into your own operations workflow.
