A Deep Dive into a Cross-Platform Build Farm
summary
BossAlien builds a hybrid build farm combining on‑prem Windows and macOS machines with AWS Linux and Windows EC2 agents, Jenkins + Perforce + EC2 Fleet, and UGS for Editor distribution. Full Windows engine+game rebuilds hit sub‑1 hour on c5d.9xlarge, Mac Minis take 3–5 hours while Mac Pros drop to ~1 hour; incremental builds and tests run ~20 minutes. Pipeline runs UBT/UAT/BuildGraph, uploads to S3/UGS, runs static analysis, Blueprint compilation, unit and functional tests, and keeps 16 editor binary revisions in Perforce while dynamically spawning cloud Windows agents and using P4 Edge servers to speed checkouts.
