I found new things.
Cristian
Course - OpenStack Security
Depth of knowledge. A true SME in Openstack. Patient and very helpful. Explained complex topics in an understandable and digestible way.
Jake McIlwaine - Gamma
Course - OpenStack Security
The trainer was extremely knowledgable and helpful. While walking through the exercises, I wasn't rushed and was allowed to make mistakes (to a point) and then help was given to correct to them where needed.
