We have been using AWS lambda for a while now and it has been a very positive experience. It also allows us to grow steadily and build on top of existing infrastructure independently. It is true though that deploying lambda and API Gateway via cloudformation is pain and this is why we don't use it. However, everything else, from IAM policies, to user and identity pools and gateway resources - it all works really well and embracing its quirkiness and limitations is the only way you will enjoy developing for this platform. If you think about it, you will not use JavaScript style programming for Rust or even Swift. You need to think with the language and platform in mind. Same is with cloud technologies. You cannot think of them in a generic way. You need to use them in the specific way they were designed to be used.
