Software-Defined Networking and Network Automation with Ansible

Modern network administration is moving away from manual, device-by-device configuration toward centralized, software-driven control. Understanding how Software-Defined Networking (SDN) pairs with automation is essential for any aspiring network professional. This text-only course guides you through the core architecture of SDN and shows you how to leverage automation tools to manage networks efficiently. You will transition from manual command-line configurations to writing structured, declarative automation scripts. What you'll learn: Understand the fundamental architecture of SDN, including the separation of the control plane and data plane; Explore how centralized controllers manage network-wide state and flow tables; Apply Ansible to automate routine network configuration tasks and state verification; Write declarative playbooks to manage switches, routers, and virtual network instances; Implement NetDevOps best practices, including version control and basic pipeline concepts for network infrastructure; Analyze modern API-driven networking protocols and contrast them with traditional command-line interfaces. You will start with foundational networking concepts, SDN terminology, and architectural models before moving on to hands-on written exercises using Ansible. The course progresses from basic control plane separation to managing network topologies through code. This course is designed for beginner network administrators, systems engineers, and IT professionals looking to transition into network automation, with no prior SDN or programming experience required.
