Lessons learned from building Fly.io Machines

Join us for a deep dive into the architecture of Fly.io's global infrastructure with JP Phillips, one of the key engineers behind Fly.io Machines. What started as a fascinating "Exit Interview" blog post - https://fly.io/blog/the-exit-intervie... - uncovering the human element behind a massive piece of technology, turned into this in-depth conversation about building and scaling a global, multi-tenant system. In this conversation, JP shares his reflections on the evolution of Fly.io Machines, the critical design decisions that shaped the platform, and the trade-offs made along the way. We explore the journey from a Nomad-based architecture to the custom-built Fly.io Machines, the reasoning behind choosing BoltDB over SQLite, and the crucial role of fly-proxy in handling traffic at a massive scale. We also take a look at some of the open-source components that power Fly.io, including a code walkthrough of the Finite State Machine (FSM) that manages the lifecycle of machines and volumes. JP explains how this simple yet powerful component ensures reliability and simplifies operations. Whether you're a software engineer, a DevOps professional, or just curious about how large-scale distributed systems are built, this conversation is packed with valuable insights and hard-earned lessons.
