Some of the AWS services have clear quota limits and it works as expected, you give me 10k widget credits and if I use 10k widget credits it stops working and I need to open a ticket. Example of this would be SES. Where it ends up being a bit of a nightmare is stuff like SMS on SNS where they would specify a quota but we could still hit it before their system reported it. We never did figure out if they were looking at a rolling monthly average and bursty campaigns could cause it to creep above their projection. This was always a manual review for this product and the only way we could avoid it was getting way higher quotas than we needed approved. Ultimately we ended up moving SMS over to Nexmo (now Vonage) for bulk SMS so we didn't have to have potential outages when the mystery quota of the now was reached.
