We're hosting Postgres on HashiCorp Nomad and ClickHouse on a separate VM for Pirsch [0]. The Postgres db is only a few kb (maybe it's a few mb now, I haven't checked in a while), as it is only used for user accounts, settings, and some configuration. It doesn't do much so it's doing OK in the cluster using a host volume on one of the machines. ClickHouse uses more storage (don't know how much right now, but it should be less than 100mb) and resources and therefore lives on its own VM. The main reason we self-host is privacy and cost. Postgres costs almost nothing, because it's part of the cluster we require anyways (also self-hosted) and ClickHouse can be scaled as needed. Hetzner has some really cheap VM, our whole setup, including the cluster, costs about 45€ a month. [0] https://pirsch.io/ https://pirsch.io/
