REST APIs, JSON/YAML, controllers, Ansible.
Modern networks expose configuration and state through APIs, not just CLI. This module covers automation concepts, controller-based architectures (SDN), data formats (JSON, YAML, XML), and the major configuration-management tools.

Manual CLI doesn't scale. Network automation reduces error, accelerates change, and enables consistency at scale. This chapter introduces the why and the high-level patterns: configuration management, intent-based, GitOps.
Software-Defined Networking separates the control plane from the data plane and exposes a centralized API. This chapter explains controllers, southbound vs northbound APIs, and intent-based software-defined fabrics.

Modern network devices expose REST APIs returning JSON. Configuration as code lives in YAML files. This chapter teaches the bare minimum to read and write both, plus a worked REST GET against a NetForge-like device.
