@ryantownsend I designed/built/ran infra where we considered 100k/s requests a nice quiet period, with ~350k/s daily peaks, plus ingest ~1TB/hour data.
Up to this scale, we never found a challenge for which cloud, containers, or Kubernetes would have been the simplest solution that could work – also far from cheapest.
All bare metal on #Gentoo. Managed with #Rex. Globally from ~30 to ~400 servers, then beyond.
Solve problems _you_ have. Not what others think you should solve.
