I worked at a company that did the same, and got the same answer. I hated that technical setup. Lambdas everywhere, Queues everywhere, microservices everywhere Exactly as you can said it was a huge pain to debug, and on top of that searching for code became a huge pain as it became split across so many different git repos, teams, and docs. And when you throw IAM on top of it all..... I am not a fan.
