Is this really an AWS issue? Sounds like you were just burning CPU cycles, which is not AWS related. WebSockets makes it sound like it was a data transfer or API gateway cost.

I doubt they would have even noticed this outrageous cost if they were running on bare-metal Xeons or Ryzen colo'd servers. You can rent real 44-core Xeon servers for like, $250/month.

So yes, it's an AWS issue.

Where, for instance ?

Hetzner for example. An EPYC 48c (96t) goes for 230 euros

Hetzner network is complete dog. They also sell you machines that are long should be EOL’ed. No serious business should be using them

What cpu do you think your workload is using on AWS?

GCP exposes their cpu models, and they have some Haswell and Broadwell lithographies in service.

Thats a 10+ year old part, for those paying attention.

Most of GCP and some AWS instances will migrate to another node when it’s faulty. Also disk is virtual. None of this applies to baremetal hetzner

Why is that relevant to what I said?

Only relevant if you care about reliability

AWS was working “fine” for about 10 years without live migration, and I’ve had several individual machines running without a reboot or outage for quite literally half a decade. Enough to hit bugs like this: https://support.hpe.com/hpesc/public/docDisplay?docId=a00092...

Anyway, depending on individual nodes to always be up for reliability is incredibly foolhardy. Things can happen, cloud isn't magic, I’ve had instances become unrecoverable. Though it is rare.

So, I still don’t understand the point, that was not exactly relevant to what I said.
