I had an AWS account I wasn't using, but I didn't want to get surprised by any bills, so I set an alert to let me know when the bill was more than $0.
Sometime later the alert went off, so I anxiously jumped into AWS to see what kind of disaster was happening, and found that I got billed a few cents... for the alert itself.
I closed it altogether after that. It's better for my sanity to just use a new email address and sign up again than to worry about surprise bills.
EDIT: It's entirely possible that I set it up wrong, or set up the wrong thing, but in any case an alert was all I was trying to do, and as far as I could tell that's what happened. I must admit I rage-quit rather than investigate too deeply.
They charge for billing alerts? I've never used AWS in production and I suppose it's a miniscule cost, but, wow, that seems really pedantic to charge for that.
Otherwise there's no incentive for application developers to optimize their usage.
In my last company we charged per unit of work, but it was possible to send a lot of requests to do a tiny amount of work -- some customers hammered us with millions of requests to do each unit of work. It wasn't malicious and it worked with their workflow, but we lost money on those customers due to all of the infrastructure required for the request routing.
The company eventually started charging a nominal fee per request, which resolved the issue.
Some service providers such as Hetzner don't even charge for bandwidth up to 20TB, but somehow AWS found a way to hike the bill per HTTP request.
I'm baffled at the complexity of just ELB pricing. Do AWS customers just not care?
You sort of had me in the first part, but you lost me here.
Charging $3 per million requests for a HTTP interface service?
How else should AWS charge for API Gateway?
(I suppose it could be bandwidth, but that doesn't make sense as API Gateway deals only in small messages; unlike ELB, S3, etc.)
