Golang is the top dog for Lambda IMO. The AWS Lambda SDK for Golang includes the entire lambda runtime so you can deploy a single 20mb binary w/ an Alpine linux base (speaking of the ECR backed lambdas) and that’s it. With NodeJS you either have to use the AWS provided centos based images which weigh in at several hundred MB or do some multistage magic to build a minimal Alpine image including the lambda runtime and AWS SDK which altogether still weighs in almost a hundred MB.

TBH, as the Dockerfile based Lambda layers have a 20GB file size limit, I'm not sure the size matters as much.

It's certainly easier to figure out what's going on in a smaller container though! I've had to debug some nasty situation with layers in Python Lambdas before and it's not fun...
