In this four (4) day course, you learn about foundational skills as they pertain to network automation and programmability. The network industry is in the midst of change, and one part of that is the operational models and technologies used to manage and operate networks on a day to day basis. For over 20 years, the CLI has been the primary means to manage networks. Going forward, we are starting to see more open and programmable network devices emerge – this means having device APIs not only on network switches, but also on SDN controllers in the form of northbound REST APIs. In addition, we are also seeing network devices be integrated with existing DevOps automation tools.
This course covers the skills needed to take advantage of these modern network devices and controller systems. The course is divided into two parts. Part 1 covers raw concepts and technologies and Part 2 focuses on automating network devices. Our typical course covers working with Cisco and Arista devices. This course adds in Juniper devices.
While there are no programming, software/dev, or automation prerequisites, students should have a good grasp on basic networking concepts.
This course is ideal for (1) network engineers looking to ramp up on their automation skills, (2) sysadmins/DevOps professionals looking to automate their network, or a combination of both.
