I’m excited to share with you the story behind our platform at Wargaming—a massive system that supports all of our games. Over time, we’ve found ourselves managing a backend powered by not one, not two, but seven different programming languages. I’ll take you through the journey of how this “zoo” of languages came to be, the challenges it presents, and most importantly, how we’ve learned to tame it. So, let’s dive into the chaos and see how we’ve learned to manage it.

Learn how to gradually replace outdated parts, manage changes without disrupting your current setup, and ensure new systems stay clean from old problems. Discover safe ways to run old and new systems together, make small improvements over time, and understand why completely overhauling everything at once is usually risky.
