Testimonials
Depth of knowledge. A true SME in Openstack. Patient and very helpful. Explained complex topics in an understandable and digestible way.
Jake McIlwaine - Sam Bultitude, Gamma
OpenStack Security Course
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.

The varied topics
Daniel Lindh - Tele 2 Sverige AB
OpenStack for Telecom Course
The broad perspective of Openstack, no chance to dive in to deep to be able to keep schedule, more to where to get information from.
Jörgen Selegran - Polystar OSIX
OpenStack Architecture and Troubleshooting Course
It was very easy communication during all the course, got answers and help in very pedagogical manner. The trainer is very experienced, I recommend him anyone who is interested in getting good knowledge in this very complicated area :-)
