Building Cross-Platform Rust Binaries: A Multi-Architecture Build Orchestration System
A comprehensive guide to building a production-grade multi-platform build orchestration system that leverages diverse hardware (from single-board computers to powerful x86_64 servers) to build native Rust binaries for macOS, Linux, FreeBSD, NetBSD, and OpenBSD across ARM64 and x86_64 architectures. Includes architecture diagrams, performance comparisons, cost analysis, and the surprising discovery that emulated ARM64 on x86_64 outperforms native ARM64 hardware by 6x.
