This course covered a lot of useful topics, and had many good examples of how to use all sorts of tools and utilities.

It taught me a lot about system administration. I have used Linux a lot as a user, in a single user-way, for a long time, but I wasn't aware of the differences with multiuser environments.

The overall style of learning seemed easy to follow, and the practical exercises and Demo Videos were also very helpful.
May 2022
It compares multiple distributions from different perspectives. It was done so well that it seemed almost like I gained a magical insight into all these distributions, and their common and unique parts, without having to go through the pain of installing and evaluating them. I have the freedom to choose the distributions, so crossing out some architectural options as a result of this course added the most value for my business, and would justify the price of the course at the end of the day.

I loved the labs/hands on exercises. I was very grateful to see that the content and labs did absolutely take a distribution agnostic approach, and created exercises that would be useful. Thank you guys! Definitely looking forward to the next course!
