At Wikimedia Foundation, we run Wikipedia, the world's favourite encyclopædia and one of the top ten websites of the Internet! No unicorns, just hardware, open source, and a small engineering org.
This talk pulls back the curtain on the stack that keeps Wikipedia fast, reliable, and resilient at global scale. Caching layers, databases, microservices, and Kubernetes are all stitched together to serve the world.
We'll also touch on how we've brought our 25-year-old monolith into the cloud-native era, and discuss the challenges we're navigating as the ongoing ~~rise of the machines~~ surge in LLM traffic changes the game.
