Weird -- the services you're utilizing are developed exactly the way you're going to avoid!
When developing a monolithic application your choices make sense. When you're taking an approach designed to allow for feature development by multiple teams in an Enterprise setting they start to be a bottleneck.
I’ve seen AWS from inside and I helped build a small part of it. Each individual product is closer to a monolith than a constellation of indispensably deployable jobs/services. The 3 products I worked on were definitely monoliths because we intentionally wanted them to be so. Obviously I don’t mean that they didn’t horizontally scale. Only that the entire app could run from 1 process, the build system produced 1 build artifact, every deployment deploys to all server, and there’s only 1 version of the app running in prod.
