Master Server Side Craft withiximiuz Labs 🚀
iximiuz [ eg-zim-ee-uhs ] — from Latin eximius, meaning "eminent, outstanding, excellent."
iximiuz Labs is an indie learning-by-doing platform created by Ivan Velichko.
For the past five years, Ivan has been helping thousands of people improve their skills and become outstanding DevOps, SRE, and Platform Engineers. This platform is his most ambitious attempt to make the learning process more fun, interactive, and efficient.

- Structured Courses - Master new technologies following a clear learning path.
At the core of iximiuz Labs is its Playground Engine, a Firecracker-powered microVM orchestrator that transforms a fleet of bare-metal servers into numerous small, isolated, and disposable sandboxes called Playgrounds.
The Playgrounds are ideal for free-form experimentation from the browser or local terminal, and they also serve as the foundation for other types of content, such as Tutorials, Challenges, and Courses.
The second key component of the platform is the Interactive Content Engine, which creates a feedback loop between a playground and the learning material on the page.
Tutorials, challenges, and courses use interactive content blocks that react to the user's actions in the playground. In tutorials and courses, these blocks help explain new concepts and provide step-by-step guidance. In challenges, they indicate the correctness of the user's solution.
From the Author
Hi there! It's Ivan, the creator of iximiuz Labs.
Since 2019, through my blog and newsletter, I've published more than 100 articles on Containers, Kubernetes, Linux, Networking, and Programming. I've also created several open source projects and spent countless hours answering questions on Twitter, Discord, and other platforms. All with a single goal: to help people master the Server Side craft.
A couple of years ago, when iximiuz.com started gaining traction, my dream evolved. I wanted to augment my static writing with a more dynamic experience - giving readers the ability to spin up carefully crafted remote sandbox environments right in their browser to experiment with Linux, Docker, and Kubernetes without needing to install anything on their local machines. This dream eventually led to the creation of iximiuz Labs.
The platform uses a Freemium model with a generous free tier. A large part of the content is (and will remain) free, and only a single-click signup is required to access the playgrounds. However, on the free tier, the daily playground time, the microVM's resources, and Internet egress traffic are significantly limited. This serves two purposes: keeps bots away and also incentivizes the most serious students to become premium members.
With iximiuz Labs Premium students get unlimited daily playtime, more powerful microVMs, and unrestricted Internet egress, allowing them to experiment with a much wider set of technologies in much more permissive environments. Trust me, you will notice the difference even if you find the free tier already good.
I'm a full-time engineer and I build and maintain iximiuz Labs in my spare time, often during late evenings and weekends. The moral support and feedback from the community have been enormous and have kept me motivated to continue working on the platform for almost two years now. However, the only way for iximiuz Labs to continue to exist and grow in the long run is by making its development sustainable. Every purchase of iximiuz Labs Premium is a vote of confidence in my work and a contribution to the platform's bright future 🚀
