It's probably not as easy as that. Lambda functions run in a container. If you have a spike in traffic, you may have 10 different containers handling requests.

It's probably not as easy as that. Lambda functions run in a container. If you have a spike in traffic, you may have 10 different containers handling requests. So should they keep 1 container always up, or 3, or 10. I suppose you could have some ELB-type rules to "auto-scale" new containers...
