Did you ever have any problems with the function concurrency limit?

It’s a soft limit. You can request a larger limit and get it increased within 30 minutes.

Awesome thanks! Sorry to bug but this is very interesting to me. Did you use a framework like Serverless?

No. I’m of the belief that when you choose a platform, go all in. Given a choice between the Serverless platform and AWS’s Serverless Application Model, I would choose SAM.

I also work for a company that pays for the business support plan, they will help you to an extent with any weirdness in their own platform - but not with third party utilities.

Another advantage with using SAM, is that you can create and configure your lambda/API Gateway from the web console and then export your SAM/CloudFormation template.

All that being said, for APIs, I don’t use either. I would recommend using standard frameworks like C#/WebAPI, JS/Node, Python/Flask/Django instead and using the proxy integration libraries that AWS provides. It lets you develop/debug locally like you are accustom to and it gives you the optionality to move your APIs to Fargate (Serverless Docker) or EC2 instances without any code changes:

C#/Web API

Node:

Python/Flask

I’ve been told that there are similar frameworks for other languages but those are the three that I use.

If you have any other questions, feel free to email me. My address is in my profile. I’m not a consultant trying to sell anything....

Thanks so much! This is really interesting. I think acloud.guru has a similar set up and they pay basically nothing for their millions of QPS. Going to research this more for my next project.
