> The point is pretty moot though, because you can schedule Cloudwatch Events every 4 minutes to keep a lambda warm, if necessary.

I encourage you to read this article, https://theburningmonk.com/2018/01/im-afraid-youre-thinking-... , because if you're running a web API with Lambdas, keeping one instance warm with the "cloudwatch event every 4 minutes" trick will most definitely not solve your cold start issues.

> I think many still repeat the "conventional wisdom" about the cold start, and never get past that point.

First comment on your article nails it. At the end of the day lambdas scheduling is a black box. People have deduced certain behavior, but AWS is explicit about not relying on undocumented behavior.

I would be loath to recommend lambda for any application where business performance is sensitive to the services latencies.
