Ok thanks for that.

Stripe: 100/second seems like perfectly ample headroom to support their payments. At $10/payment, that's $1K/s which is $3.6 Million in one hour.

If that's 'The Stripe Limit' that every Stripe customer has, wouldn't it kind of imply that's plenty enough for even much bigger customers?

As 'FaaS' scaling - as far as I knew that was the entire point of Lambdas - that they could scale quite quickly.

The alternative, EC2s would need to also 'scale very quickly' and could very well run into the same 'prioritization' problems, no?

In reality, I don't think there's a problem here with Lambda - while possibly not the most ideal option - I think that AWS has ample overhead to supply this little company with their little burst.

Amazon accommodates some pretty big workloads. A call to AWS support may very well have supplied them with the answer as to the real limits on scale.
