We do, power activity feeds and chat for a billion end users using cloudformation, cloud-init and puppet on the infra side. Code is based on Go, rocksdb and raft. Don't see why we would want the overhead of K8 and docker. Infrastructure is already defined in code, everything is redundant and automated, why have 1 extra layer that can break and cause performance issues? Use docker for local dev though its good for that.
