Ansible is an easy-to-use IT automation engine. It can transform and optimize tasks such as rolling updates with just a few lines of code. However, many organizations aren't using Ansible modules and playbooks in a reusable fashion; they are reinventing the wheel every time they automate. This training course introduces intermediate to advanced use cases for using the tool at scale
