We are using AWS CDK too! CDK is freaking AWESOME to write Infrastructure as Code. AWS CDK https://anjith-p.medium.com/writing-infrastructure-as-code-w...

Yes in my opinion the right division is

GOOD 1 lambda = 1 service

BAD 1 lambda = 1 endpoint

I'm eager to chat with you about CDK since it's kind of new and I don't know anyone else using it. Feel free to write me at giorgio DOT zamparelli AT gmail DOT com to chat about CDK, Lambda, serverless, Infrastructure as Code.
