Meet Your OpenStack Training Instructor: Polina Petriuk

Next up in our “Meet your OpenStack Training Instructor” series, our interview subject is Polina Petriuk.

Tell us more about your background. How did you become involved in OpenStack training?


In software development, I started as a QA Engineer, but I’ve never had any problems doing any other non-QA tasks. That gave me experience in a lot of areas beyond QA, such as business analysis and requirements gathering, datacenter planning, deployment and support, system administration and devops, and project and program management. When the opportunity to become an OpenStack trainer came up, it seemed like a perfect match for my background, skillset, and passion.

What do you enjoy most about training?

It never gets boring. I think I learn as much from my students as they do from me :-) I have students from different countries and companies, with different backgrounds and skills. I have an opportunity to talk to them and get to know what they think and how they do things. Also, my work involves a lot of traveling, which brings a whole different aspect of excitement. There is always something interesting to see and do in the new cities that I am exploring.

What particular challenges or opportunities will Mirantis OpenStack training help students meet?

OpenStack gets a lot of attention, and there clearly isn’t a shortage of information available online. The problem, however, is that this information is all over the place.

Mirantis OpenStack training solves this by presenting a holistic view of OpenStack. It focuses on giving the students the big picture and provides a better understanding of the logic behind how OpenStack works. I often tell my students that the goal is to learn what keywords to use in Google to narrow down the search results when looking for an answer to a particular question. :)


The course also facilitates interaction and collaboration between students. We often have people who have already tried OpenStack and even have it running in production. Such students have valuable experiences that they can share with the rest of the class. Mirantis instructors are also there to share the knowledge they have gained from various Mirantis customer projects, encouraging a truly collaborative learning environment.

What kinds of professionals are most likely to benefit from participating in this class?

Anyone who needs to understand how OpenStack ticks will find the training valuable. However, Solution Architects and DevOps are probably the ones that benefit the most from the entire training, start to end.


What advice would you give our readers who want to learn more about OpenStack?

Come to Mirantis training, of course. :-)

Additionally, has a lot of useful information. For students who need hands-on experience, I also recommend installing OpenStack in VM using devstack or vagrant scripts with default options and then try to add or remove things. Google Search is your best friend there.

One interesting fact or story abut you that your students would be surprised to learn?

Hmm, I actually have two. I have a major in aerospace materials and designed the wings for a two-seat airplane manufactured by a small private company in Ukraine.

My grandmother and mother are both school teachers, and my sister and father teach in university. Growing up, I was expected to follow in their footsteps and go into education. But, I was really against the idea and chose the technology path instead. My mom often laughs at me now, saying that I couldn’t avoid my destiny of teaching. :)
