> No, because most self-hosted services are 10-20x cheaper than comparable SaaS offerings.

This has nothing to do with the fact that it could be hit by a botnet, as per the exact point I commented on, could 'wreck your card', it's simply a question of scale.

No. Most self-hosted services have no bandwidth costs, at all.

Or they have bandwidth costs around a dollar per terabyte. Which, even when maxing your connections, would always be below your actual server costs.

If you read the fine print of the ones with "no bandwidth costs" you'll find that service becomes throttled after a certain level of usage. These are businesses, they have to make money to operate, they're not in this for charity

Dude, I’ve used 180 TB of traffic in one month on a 16$/mo server, and still, no throttling.

I’ve read the fine print, and called them.

Online, Scaleway, OVH, do not ever throttle you.

Hetzner requires you to buy traffic, but there it costs 1$ per 1TB of traffic, which is 1000x cheaper than Firebase.

But legitimately using lots of bandwidth isn't the same as a DoS attack. Try and remember that bandwidth isn't the only resource being used.

In my experience they throttle your CPU usage after a while.

At no point did I suggest using Firebase was a good idea. I said it's always cheaper to run your own services in the long run, and that they'd have found out their own problems (see my first reply) sooner.

But my point is that you won't even ever have an issue with overusing traffic or CPU during a DoS, and the issue will be purely that your bandwidth will be saturated.

Vs. AWS, Firebase, etc where your limit will be your bank account instead.
