Overview of this book

Network Automation Cookbook is designed to help system administrators, network engineers, and infrastructure automation engineers to centrally manage switches, routers, and other devices in their organization's network. This book will help you gain hands-on experience in automating enterprise networks and take you through core network automation techniques using the latest version of Ansible and Python. With the help of practical recipes, you'll learn how to build a network infrastructure that can be easily managed and updated as it scales through a large number of devices. You'll also cover topics related to security automation and get to grips with essential techniques to maintain network robustness. As you make progress, the book will show you how to automate networks on public cloud providers such as AWS, Google Cloud Platform, and Azure. Finally, you will get up and running with Ansible 2.9 and discover troubleshooting techniques and network automation best practices. By the end of this book, you'll be able to use Ansible to automate modern network devices and integrate third-party tools such as NAPALM, NetBox, and Batfish easily to build robust network automation solutions.

Deploying VPCs using Ansible

In this recipe, we will outline how to deploy AWS VPCs using Ansible. AWS VPCs are the foundational networking construct in AWS and they can be thought of as a virtual data center within the cloud that the administrator creates within their AWS account. In order to start building any other infrastructure-related services within AWS, a VPC must first be created. We will outline how to describe all the required VPCs and how to automate their creation using Ansible.

Getting ready

To connect to the AWS API, the AWS control machine must be connected to the internet. The AWS account must also be prepared, as outlined in the previous recipe, with the required AWS credentials.
