One thing I've learned from talking to AWS support is that increasing memory also gets you more vCPUs per container. ----- Serverless is great in scaling and handling bursts, but you may find it VERY difficult in terms of testing and debugging. A while back I started using an open source tool called localstack[1] to mirror some AWS services locally. Despite some small discrepancies in certain APIs (which are totally expected), it's made testing a lot easier for me. Something worth looking into if testing serverless code is causing you headaches.
