> Infinite concurrency is a bit of a curse. Want to use that MySQL DB that contains all your business critical data? Better use some MySQL Serverless proxy nonsense because unbounded connections isn't fun. Or just set the Lambda concurrency to a fixed value proportional to your MySQL DB's capacity. It's an easy parameter. > Unpredictable runtime makes observability more complicated, probably forcing you into poor decisions as a result, i.e prom push gateway. This is just nonsense. What is "unpredictable" about the runtime? What is difficult about enabling X-Ray? > Runtime/execution time limits mean people trying to do all-serverless end up doing horrible things to accomplish long-running tasks. "All-serverless" is just as stupid an idea as "no-serverless." Aside from lock-in, your "cons" are just the cons of anyone trying to build large-scale systems without knowing what they are doing. There is absolutely no way anyone who read the documentation would run into your cons of serverless. https://docs.aws.amazon.com/wellarchitected/latest/serverless-applications-lens/welcome.html https://docs.aws.amazon.com/wellarchitected/latest/serverles...
