Prerequisite knowledge

  • Familiarity with Kubernetes

What you'll learn

  • Explore a complicated migration to Kubernetes


Netlify is the best platform to build, deploy, and scale modern web projects. The company’s deployment pipeline processes thousands of deploy jobs every day, where people automate building any kinds of modern web projects, from basic websites to single-page applications using modern tools like webpack, WebAssembly, Rust, and Go.

Netlify recently moved this deployment platform from a traditional architecture with a central broker queue and pools of virtual machines to a cloud-native architecture where Kubernetes plays a central role, but the story isn’t so simple. The migration was supposed to be able to switch between both architectures without downtime, but the team ran into unexpected problems, including a bug in Docker Engine. David Calavera shares the lessons Netlify learned during the migration that made the company roll the migration back and explains how they rolled it again—all without affecting production availability. David also discusses the economics of adopting a cloud-native approach and the economic benefits of the new architecture.
