Cold starts may delay realtime use
From 2 comments
Does this method run into the typical lambda cold start problem? If not, how does it get mitigated without say, a regular cron job polling the endpoint?

Questions
How to test serverless apps locally
From 2 comments
How can you test this or other serverless apps? Is it possible to run a local env that replicates AWS?
fabricexpert on HNI was wondering this too a few years back when serverless started to gain traction. I remember thinking it sounded like a lot of mock infrastructure. Just did a search and found…

What are the costs at scale
From 1 comment
what about costs? How many requests will occur in the lambda side with sockets? It's an interesting concept.
