This was the best course I've ever taken. The instructor was just GREAT!
I don't usually like online training, but this training was great and Eric is really good, well-organized, and in control. The way he engaged each participants is amazing, and how he troubleshoot issues.
Even though I've been using Chef for three years, I found this class immensely useful; not only did it allow me to examine and compare my current practices to those presented in the training, but I learned several new techniques for using Chef tools.
It was great.
The lab setups are excellent and allow the class to focus on the training objectives. It was a great way to get hands on experience with Compliance in one day.
Excellent information presented by an experienced practitioner and an excellent presenter.
This was the best training class I've taken. It was online using Zoom, it was super easy to share code and collaborate. The instructor kept everything going at a perfect pace and his knowledge and expertise on the topic was evident. 22 years of training in my career and this was hands down the best class I've taken. Better than classroom training. Looking forward to more!
