As we have explored Ansible throughout this book, we have shown many times that the more your playbook grows in size and scale, the more likely you are to want to divide it up into multiple files and directories. A great example of this is roles, which we covered in Chapter 4, Playbooks and Roles, where we defined roles to not only enable us to reuse common automation code but also to split up what could potentially be a massive, single playbook into smaller, logically organized, manageable chunks. We also looked, in Chapter 3, Defining Your Inventory, at the process of defining your inventory file and how you can also split this up across multiple files and directories. What we have not looked at, however, is how we can put all of this together. All of this is documented in the official Ansible documentation at https://docs.ansible.com/ansible/latest...

Overview of this book
Ansible enables you to automate software provisioning, configuration management, and application roll-outs, and can be used as a deployment and orchestration tool. While Ansible provides simple yet powerful features to automate multi-layer environments using agentless communication, it can also solve other critical IT challenges, such as ensuring continuous integration and continuous deployment (CI/CD) with zero downtime.
In this book, you'll work with Ansible 2.9 and learn to solve complex issues quickly with the help of task-oriented scenarios. You'll start by installing and configuring Ansible on Linux and macOS to automate monotonous and repetitive IT tasks and get to grips with concepts such as playbooks, inventories, and network modules. As you progress, you'll gain insight into the YAML syntax and learn how to port between Ansible versions. In addition to this, you'll also understand how Ansible enables you to orchestrate multi-layer environments such as networks, containers, and the cloud.
By the end of this Ansible book, you'll be well - versed in writing playbooks and other related Ansible code to overcome just about all of your IT challenges, from infrastructure-as-code provisioning to application deployments, and even handling the mundane day-to-day maintenance tasks that take up so much valuable time.
