Ask HN: Has AWS ever surprised you with a bill?
14 comments
Yeah, it's a meme at this point that if you're learning AWS, expect to be homeless because you left the EC2 on. Maybe not that bad, but I feel like most people have the logging to detect spikes etc, except those who don't know how to do logging.
Funny enough, AWS has added recursive lambda call prevention within the last two years.

Yep — we got hit with a ~$1.8k bill spike on AWS due to a Lambda function caught in a recursive loop during a staging deploy. It kept calling itself due to a misconfigured trigger — we didn’t catch it for ~6 hours because it wasn’t high-traffic, just persistent.
And $15/m would be interesting to not have this problem ever again? Is there anything else that would be cool to have with that?
I would not pay anything for a tool to fix this because you can handle it yourself with logging, budgets, and various alerts. The people who are willing to pay for this would likely only pay for it for a few months, until they learn AWS enough to protect themselves from it on their own.
So while the road you are looking down has some validity, it is also a high-churn product idea that only holds value for people who are brand new to AWS. I'd be hesitant to dedicate much time to such a narrow market.

DynamoDB got me for a couple hundred in college after I used it for a hackathon. Fortunately support was kind to me and wiped it after I explained.

No that wouldn’t be worth it at all.

hi there, this is a problem I have been thinking about a lot lately as a recent entrepreneur. I would love to chat more and collaborate, please feel free to mail me (email in profile). thank you.
No, only Datadog has done that to me.
Nope.
I personally don't use any AWS constructs, just reserve EC2s as needed and host everything myself.

Trying to talk to 10 devs or engineers who’ve been hit by unexpected AWS charges (Lambda loops, S3 egress, log retention, etc).
Not selling anything. Just want to understand:
- What caused it? - How you found out? - What you tried after? - Would a $15/mo tool with IaC cost-diff + Slack alerts have helped?
If that’s you (or your team), I’d love to hear from you.
