summary

Andromeda is Google Cloud’s network virtualization stack that uses a hierarchy of controllers plus Hoverboard gateways to avoid programming the long tail of mostly idle flows and offloads high‑bandwidth VM pairs once they exceed ~100 kb/s (results: >99.5% of traffic bypasses hoverboards). On hosts an OS bypass fast path plus per‑VM coprocessors handles packets; a single core hits ~38 Gbps and round‑trip latency ranges ~25 μs (15 μs w/ busy polling, ~9 μs with DPDK). Design scales to 100,000 VMs per network; 40k‑VM programming time falls from ~67s to ~2s; upgrades cause ~270 ms median blackout.
