Well, their comment section is fore sure not running on premises, but on the cloud:

"An error occurred: API rate limit already exceeded for installation ID 73591946."

> We use SSDs for reliability and speed.

Hey, how do SSDs fail lately? Do they ... vanish off the bus still? Or do they go into read only mode?

In case anyone from comma.ai reads this: "CTO @ comma.ai" the link at the end is broken, it’s relative instead of absolute.

Interesting that they go for no redundancy

Hetzner bare metal ran much of crypto for many years before they cracked down on it.

TLDR:

> In comma’s case I estimate we’ve spent ~5M on our data center, and we would have spent 25M+ had we done the same things in the cloud.

IMO, that's the biggie. It's enough to justify paying someone to run their datacenter. I wish there was a bit more detail to justify those assumptions, though.

That being said, if their needs grow by orders of magnitude, I'd anticipate that they would want to move their servers somewhere with cheaper electricity.

Is there a client to sell on your own unused private cloud?

I like Hotz’s style: simply and straightforwardly attempting the difficult and complex. I always get the impression: “You don’t need to be too fancy or clever. You don’t need permission or credentials. You just need to go out and do the thing. What are you waiting for?”

mark my words. cloud will fall out of fashion, but it will come back in fashion under another name in some amount of years. its cyclical.

I've just shifted to Hetzner, no regret
