This document discusses using Ansible for infrastructure automation. It provides examples of how Ansible can be used for provisioning infrastructure, configuring servers, patching, backups, cluster deployment, and scaling. It also gives three use cases: creating a platform for a client, integrating Ansible with other tools like vRA and CyberArk, and automating a two year project involving RedHat and Windows systems. It concludes by discussing common problems providing "DevOps as a service" and introducing Crevise PowerOps to address these.
