Ansible Configuration Management Boot Camp

Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. Designed for multi-tier deployments since day one, Ansible models your IT infrastructure by describing how all of your systems inter-relate, rather than just managing one system at a time. It uses no agents and no additional custom security infrastructure, so it's easy to deploy — and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English.

This Ansible training course demonstrates the flexibility and power of the Ansible configuration management system, and how it can be used to build and scale highly reliable infrastructure for your own environments and projects. Using real-world examples, we demonstrate how Ansible can be used to manage environments as small as a couple of servers, or for massively distributed infrastructure that spans the globe — all with the same simple syntax.

By the end of this course, you will have a solid understanding and hands-on experience building reliable and easily reproducible infrastructure using Ansible, and the knowledge to integrate Ansible into your operations workflow. Our continuous hands-on lab classroom format and real-world practice scenarios cement your new skills with Ansible's tools and leave you prepared to begin taking advantage of radically simple configuration management.
