I’ve seen many claim this but I just haven’t experienced it in production and I’m not sure why. We use lambda at my work and we serve several million users a month. Lambda bill comes out to around 200$ a month, not exaggerating. API gateway ends up being more expensive every month than lambda. I’m asking not to seem snarky, I truly want to know what is making people hit high prices with lambda. Is it like functions that are super computationally intensive and require queued lambda functions?

In my business, we heavily use FaaS, and I agree that it seems economical. It's a little surprising, though. AWS Lambda is 5 to 6 times higher price per second than an EC2 instance for a given level of memory and CPU. Our application simply doesn't need much CPU time. Other aspects (database, storage) are more expensive. The main advantage, though, is predictability of operations. The FaaS services "just work". If we accidentally make a change to one endpoint to consume too much resources, it doesn't affect anything else. It's great for allowing fast changes to new functionality without much risk of breaking mature features.
