Most databases expressly say don’t run storage over a network.

To be fair, most networked filesystems are nowhere near as good as EBS. That’s one AWS service that takes real work to replicate on-prem.

OTOH, as noted, EBS does not perform as well as native NVMe and is hilariously expensive if you try. And quite a few use cases are just fine on plain old NVMe.

Thats because EBS is a network block device and not a network filesystem - that would be EFS. And with network block devices you get the same perf and better compared to EBS.

Yes. We have it 4x striped on those same machines. Burns like lightning.

I have one of those. It’s so fast I don’t even know what to do with it.

The only problem is it hides all of the horrible queries. Ah well, can’t have it all.

Ha, I did just the same thing - and also optimized for an extremely fast per-thread CPU (which you never get from managed service providers).

The query times are incredible.

Funny enough, the easiest way to experience this is probably to do some performance experimentation on the machine you code on. If it's a laptop made in the last few years, the performance you can get out of it knowing that it's sipping on a 45W power brick with probably not great cooling will make you very skeptical of when people talk about "scale".
