Cheaper, faster, in house people understands what’s going on. It should be a given for many services but somehow it’s not.

I totally agree with you. Where I work, we self-host almost everything. Exceptions are we use a CDN for one area where we want lower latency, and we use BigQuery when we need to parse a few billion datapoints into something usable.

It's amazing how few problems we have. Honestly, I don't think we have to worry about configuration issues as often as people who rely on the cloud.

On premise? Or do you build servers in a data center? Or do you lease dedicated servers?

We have our own data center with servers. The upfront costs are high, but it was worth it in our use-case

Not GP, but my company also self-hosts. We rent rackspace in a colo. We used to keep my team's research server in the back closet before we went full-remote.
