Learn the concepts that are required for automating our network.

Fundamentals of DevOps

This module starts with automating network reconnaissance. We'll accomplish this by gathering important information from network devices while building a library of dynamic on-demand utilities and generating living documentation. Starting small, the module exhibits the simplicity and elegance of network automation.
We'll then learn how to automate larger changes that require a high number of repetitive steps. These changes will be executed serially in a specific orchestrated order, making them perfect for an automated solution. After becoming comfortable with these new tools, we’ll be able to fully transform any network configuration management into an automated, intent-based, self-documenting system.
In the end, we'll learn how to migrate to a continuous integration/continuous delivery (CI/CD) pipeline, thereby fully automating the network.
