Managing Cisco Networks via Infrastructure as Code
What if you could manage your IT environment like a code project? After teaching network fundamentals, this course explores the details of Infrastructure as Code. It focuses on model-driven programmability applied to Cisco networking products.
What you'll learn
Cut through the buzzwords around IT infrastructure automation and orchestration with this course. In this course, Managing Cisco Networks via Infrastructure as Code, you will gain the ability to design, deploy, and manage networks using modern automation techniques. First, you will learn the fundamentals of networking such as IP routing, Ethernet switching, and critical network services (DHCP, DNS, NAT, SNMP, and NTP). Next, you will discover the capabilities of common Infrastructure as Code frameworks such as Cisco pyATS, Puppet, and Ansible. Finally, you will explore network-oriented model-driven programmability by exploring YANG, NETCONF, and RESTCONF. This includes demonstrations hosted on Cisco DevNet sandboxes using Cisco IOS-XE and Cisco Nexus platforms. When you’re finished with this course, you will have the skills and knowledge of a junior network automation engineer needed to successfully automate your production systems.
