Deploying python flask app on aws lambda container

Give https://github.com/zappa/Zappa a go, or google "flask lambda" for other options. We had good results with zappa & django with a fairly large app where zappa was used to package it, then it was deployed as a container lambda. It supports zip lambda deployment directly but we found the container option worked better for a larger app.

You can try Lambda Adapter (https://github.com/awslabs/aws-lambda-web-adapter). The idea is to wrap your web app with a layer that will convert Lambda events into emualated http requests, so you can use any web framework.
