What Our Clients Say

“Given the breadth of the course, I think it was very well structured and organised, I got a lot
out of it.”     

 

JVM Tuning - Bespoke Course

Live Online - May 2020

 

“This was an excellent course and was lots of fun to attend. Instructor started with basic intro to
containerization, then explained Kubernetes and the different components (Container
engine, orchestrator, control plane) which all made sense because of the containerization
intro. The parts of the course layered on top of one another to give a good understanding of
Kubernetes.”
