It does depend on the architecture and framework they are using imo. I have a single Hetzer machine with spinning plate HDs that serves between 1-2 million requests per day hitting DB and ML models and rarely every gets over 1% CPU usage. I have pressure-tested it to around 3k reqs/sec. On the other hand I have seen WP and CodeIgniter setups that even with 5 copies running on the largest AWS instances available, "optimized" to the hilt, caching everywhere possible, etc. absolute crumble under the load of 3k req per min. (not sec ... min).

Many frameworks that make early development easy fuck you later during growth with ORM calls, tons of unnecessary text in the DB, etc.

Keep in mind that your Hetzner instance has locally-attached storage and a real CPU as opposed to networked storage and a slice of a CPU, so I'm not surprised at all that this beats an AWS setup even on the more expensive instances.

Yes, frameworks can be a problem (although including WP in the list is an insult to other, actually decent frameworks), but I would bet good money if they moved their setup to a Hetzner setup it would still fly. Non-optimal ORM calls can be optimized manually without necessarily dropping the framework altogether.

Hum... The Hetzner instance is very likely cheaper than any AWS setup, so while there is a point in that part, it's not a very relevant one. (And that's exactly the issue with the "modern DevOps" tooling.)

This sounds like some other architectural problems - running nowhere near the largest instances available that was single node performance on EC2 in the 2000s.

There are concerns switching from local to SAN storage, of course, but that’s also shifting the problem if you care about durability.

Can you clarify what you mean by "tons of unnecessary text in the DB"?
