With AWS Lambda I try to avoid using API Gateway as it seems to me that is exactly where the lock-in occurs. Instead I have one catch-all route on API GW and I keep my routing layer in the app. This also makes it easier to run the app on dev without recreating the entire AWS environment
If you work for any size corporation, they aren’t going to just switch their infrastructure because a developer said that they pinky promise the migration will be easy.
You’re always for all practical purposes locked into your infrastructure once your business grows.
