     Requirements

  • Basic Linux administration skills
  • Basic networking knowledge
  • Basic knowledge of cloud computing paradigm
  • Basic practical and theoretical knowledge of OpenStack
 

     Overview

The aim of this course is twofold - gain solid knowledge about OpenStack architecture and acquire profound troubleshooting skills. In the architecture part you will learn how to design the hardware for the public and private cloud, prepare high-availability control plane, choose proper size of the flavours, and safely overcommit cloud resources, among other things. Getting knowledge about the internals of Neutron (Networking Service) is another essential part in OpenStack architecture. Next the participant will be introduced into methods of troubleshooting issues in OpenStack clusters starting from general tips, through network troubleshooting up to caveats of main OpenStack services. Around 75% of the course comprises of hands-on workshops in the real OpenStack training environment.

Jan Gustafsson - Polystar OSIX


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 :-)

Polystar OSIX


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


A good mix of hands on exercises and lectures!

Polystar OSIX


The flexibility to answer questions. Good pdf, good examples

Conny Vigström - Polystar OSIX


Damian, is very skilled, I'm very pleased with everything, no complains, best training session I've participated in for a long time… It's very difficult to have a training course like this, totally remote, you did a great job, It went very well, there were no issues.

Peter Erlandsson - Polystar OSIX


The virtual desktop in a browser feature was kind of neat.

Mikael Karlsson - Polystar OSIX


The network parts.
