What basic preparation do I need to complete the assignments?
You will need confident terminal (console) skills, basic knowledge of client-server applications, and an understanding of Linux at the user level.
How long is the course?
The support period is 6 months for the full program and 4 months for the shortened one.
How much does the training cost?
The price depends on your level, so it is set individually. But I can say right away that it is much cheaper than the cost of popular courses on well-known platforms, and they do not provide an individual approach.
What if I have already purchased courses on your platform?
Then the cost of the training program will be lower for you, as I take this into account when calculating the price.
What is the difference from similar courses on well-known educational services?
I recommend studying the comparison table on the program page.

About Me
I have been in IT since 1999, when I started developing, as well as setting up and maintaining servers. Back then, the term DevOps didn't exist yet, but some of the practices did. Over the years, I increasingly wanted to move away from development and set up CI/CD processes in the company, which I eventually did.
A few years ago, the idea of creating practical courses on my own platform came up, and fortunately, my development experience allowed me to implement this easily. Even then, it was clear to me that popular educational platforms were heading in the wrong direction, and their price/quality ratio was far from ideal. Thus, the DevopsTrain project was born. I am confident that the future lies not in the mass segment, but in a personalized approach.
When working with me, you can expect the following:
- Expert knowledge of the field
- Attentive attitude to each student
- Excellent price/result ratio
- Openness to feedback
Feel free to reach out!
