(from earlier courses)
I highly recommend both courses (Ansible and Netmiko) for those looking to learn more about network automation. Kirk Byers does a great job at explaining the content, provides the lab resources required to perform the course material, and is good at responding to questions on his Slack Channel.Andrew Turner
I have taken several paid and non-paid Python courses. I can say that by far your course is the best one I have taken. The way you explained stuff just makes sense to me.Joli MartinezAutomation Engineer
I am on the material for the 3rd week and I just wanted to compliment you on the way that you explained how to unwrap the data structures. Best step by step explanation I have seen so far to help me understand and work with the data. Thank you very much!Ray deGuzmanSenior Network Engineer

*Course content is subject to change. Any changes should be minor, however.
What is the format of the course?
This course is a twelve lesson, four-week email course. The lessons are sent every Monday, Wednesday, and Friday. The lessons contain videos, and potentially exercises and additional content (not all lessons will contain exercises, but most will). We will post solutions to the exercises online. The Plus Package will have a community forum where you can ask questions and interact with me and with the other students.
Is there a lab environment?
Yes, there will be a simple Linux lab environment that you can SSH into. This lab environment will allow you to easily use Git. Alternatively, you can install and configure Git in your local environment.
What are the prerequisites for the course?
Since the lab environment will use Linux, you should be at least somewhat familiar with Linux. You should know the basics of how to move around the file system, execute shell commands, and edit a file. Note, the lab environment is optional and you can also install Git locally on your own computer.
Git is the predominant version control system currently in use. It allows you to manage both automation code and text-based infrastructure files. It also enable the integration of CI/CD into your environment. CI/CD enables systematic and automated testing of changes.
What is the community forum?
The community forum is a forum where students can interact, ask questions, and make recommendations. Students that purchase the Plus Package will have access to the community forum for the duration of the course.
What if I am unsatisfied with the course after I sign-up?
If you are not satisfied with the course, there is a 15-day money back guarantee. No questions asked.
