I know you wrote /s, but this has basically nothing to do with the tech of microservices, and more to do with internal politics.

Switch the ”user microservice” to ”birth date is not indexed in the database and i have to reach out to the database handling team” and you are in the same situation

Tbh mostly microservices solves two issues for me:

1. You can scale resource-heavy operations without an impact of scaling everything else.
2. You kind of ”force” people to keep things contained, instead of making everything interdependant. Which helps containing issues with updates to certain functionality to only have an impact on that functionality.

You could do #2 in a ”monolithic” setup as well (by doing modules or libraries or something), it just never works out that way in practice

Imo they do not add problems, but they do exchange some problems for other problems.
