Gaming at Scale: What we learned from building our own multiplayer environment
summary
Engineers build a multiplayer Minecraft environment that uses Nomad to run Node.js bot containers, Terraform to deploy across clouds and regions, and Datadog for observability. The system scales to a 256-player server, spawns dozens of bots (demo shows ~47 active bots), and at full scale runs ~168 instances across many regions and three clouds; the 3‑day demo bill is about $1,700. Infrastructure is codified, autoscaled, region-aware, and demonstrated working end-to-end.
