This document discusses using infrastructure as code and DevOps tools like Ansible to automate the provisioning of environments. It describes how playbooks can be used to define tasks like installing a JDK and Tomcat, deploying applications, and destroying environments. A demo is provided of using Ansible to create a Docker network, install software on containers, and manage inventory. The key points are that infrastructure as code and automation tools allow environments to be provisioned on demand and scaled easily while avoiding manual errors.
