This lab introduces the Network as Code approach for Cisco Catalyst Center, enabling separation of data defined in YAML files from infrastructure logic implemented with Terraform. Using a structured, open-source data model, attendees can efficiently manage Catalyst Center services, including SD-Access fabrics, and quickly deploy network environments with minimal automation experience. Participants will learn how Terraform providers and modules translate desired state into operational configurations, support inventory-driven deployments, and reconcile configuration drift. The lab demonstrates inventory-driven deployments, centralized defaults, and reusable modules to simplify large-scale network configuration.
