This facilitates a benefit that I think has been described as "self-contained systems". There's one website on the topic, that imho is too narrowly focused and seeks to distinguish itself from microservices incorrectly, I think. That said, a self-contained system in the context of a container orchestration framework, docker-compose, kubernetes, etc, facilitates an number of benefits, not the least of which is the ease of scaling engineering staff. For example, in typical organizations that claim to have modern development practices, there are static dev, test, and staging environments for a given service. Obviously these are subject to config skew, etc. and must be time-shared between folks. When it's a simple task to create an environment per engineer for each purpose or any other, that can accelerate development tremendously. There are other benefits around resilience in production, but that's another topic entirely.
