Hmm. Are you sure? The article says AWS documents the behavior, but there is no way to configure it. They tried forcing an early shutdown, but that caused AWS to record an error event.

What's the default though? Because if the 7min thing happen with default settings, then it's definitely blog post worthy.

What's documented is that memory is billed for as long as the environment is active. What's not documented is how long those environments actually remain alive after their last request, and there's no configurable idle timeout.

And for context, Easel.sh is an alternative to Vercel, not AWS. Easel actually uses traditional Lambda as part of its core infrastructure. I was hoping Web Functions could replace some of the custom infrastructure we'd built on top of it, but the idle-memory billing made it a poor fit for our workload.

I thought the findings were worth sharing.
