We host our own CockroachDB cluster on 3 baremetal machines. We also host 2 separate PostgreSQL instances, each with an asynchronous replica (which serve some of the read queries) and with bareman for PITR. The PG instances used to be on RDS. The performance difference (and cost savings) is....at least least 10x. We have no devops/sysadmins.
