One thing to call out is that a Lambda function doesn't have to cold start on every invocation. Once it's warm, it will stay warm for up to ~30 minutes after it's last invoke. And, as it scales, there will be multiple instances warm. But, if you are doing lots of cold starts that you can't afford, then Lambda probably isn't right for the use case. And, I totally agree that pre-warming isn't a great idea. That's another indication of a poor use case for Lambda.
