About the issue on AWS Lambda, have you taken a look at other options such as Cloud Run or Fargate. I think they would better serve your use case.

Edit.

To be specific, the limit on runtime of the container. It is longer on the services I mentioned above.

Thank you for recommending these! Our problems is not related to Lambda functions though, they can run for minutes. It is the API Gateway that shuts the connection after 30 seconds. We might just need to build our own web server.

Also worth looking into using ALB instead of API Gateway, and have ALB call Lambda (I think this is possible).
