Overview of this book

Network automation is the use of IT controls to supervise and carry out every-day network management functions. It plays a key role in network virtualization technologies and network functions. The book starts by providing an introduction to network automation, SDN, and its applications, which include integrating DevOps tools to automate the network efficiently. It then guides you through different network automation tasks and covers various data digging and reporting methodologies such as IPv6 migration, DC relocations, and interface parsing, all the while retaining security and improving data center robustness. The book then moves on to the use of Python and the management of SSH keys for machine-to-machine (M2M) communication, all followed by practical use cases. The book also covers the importance of Ansible for network automation including best practices in automation, ways to test automated networks using different tools, and other important techniques. By the end of the book, you will be well acquainted with the various aspects of network automation.

Ansible overview and terminology


Ansible is an automation tool or platform, which is available as open source, and used to configure devices such as routers, switches, and various types of servers. Ansible's primary purpose is to configure three main type of tasks:

  • Configuration management: This is used to fetch and push configs on various devices that we call as inventory in Ansible. Based upon the type of inventory, Ansible is capable of pushing in bulk specific or full configs.
  • Application deployment: In server scenarios, many a time we need to bulk deploy some specific applications or patches. Ansible takes care of that as well as bulk uploading patches or applications on the server, installing on them, and even configuring the applications of a particular task. Ansible can also take care of customizing settings based upon the devices in the inventory.
  • Task automation: This is a feature of Ansible that performs a certain written task on a single device or a group of devices. The tasks can...
