Build a serious Raspberry Pi cluster, no tower stacks, no tangled cables.
I’ll show you how I mounted 8 Raspberry Pi 5s in a rack with NVMe storage PoE support, ran production-grade workloads with Kubernetes and gRPC and matched $500/month cloud performance for a fraction of the cost.
Use time.After in Go to implement simple timeouts for quick operations and fallback logic — no context required, just clean and effective control.
