Discovering the robot marketplace (thanks to HN) was an eye opening experience for me that showed me dedicated servers were viable and could be competitive with the VPSes I'd been purchasing/using for years (I was so excited I wrote blog posts about it). I've recently been thinking about making a subreddit for hetzner (r/hetzner), so fellow users can talk with each other but I am worried it would do more harm than good (increasing the burden on them in terms of having to do PR in yet-another part of the internet that can be pretty toxic in terms of community at times).
You can even deploy to them with terraform.

I feel like I say the same thing all the time, but I'll repeat it again here -- if devops/infrastructure goes at all correctly in my mind, going to one vendor for both your compute/data and your value-added services (so asking AWS for EC2 machines and to run RDS on top of them for you and offer support) is going to dissipate.
Smaller companies can run sufficiently niche (many might disagree but I think running postgres is within this ) with more innovation and decent support for less cost than Amazon can. The vast majority of people who run RDS with something like Postgres as a backend are unlikely to run into crazy issues simply due to how well postgres is built, and how well known it is, outside of gross misconfiguration.
Companies are already offering on-your-cloud solutions that use EC2 machines to run their own software and offer support on top -- as container orchestration systems become even more widespread I think people will stop asking AWS or GCP for more than basic compute/data and a few tools they're really good at, and go to more specialized smaller vendors.
If you really want to penny-pinch unbundled solutions that charge you separately for compute, storage and ip addresses might be even cheaper, e.g. on scaleway you could get way with 1€/month if you go ipv6-only on their smallest instance type with a minimal amount of storage. Plus you get unlimited traffic with them.
I'm really digging their baremetal and ARM offerings -- both C2M and C2L look great to me and no setup costs is even better.
While I don't know if it's worth the headache to try that hard to cost-maximize I love that it's an option! I'm personally OK with paying more for a bit more breathing room on the utilization side (good ops is to keep your servers @ no more than 70% in case of burst right?).
