At the beginning of my career I always choose fun names and was strongly in the camp of having fun names to identify better with my projects.
After a few years, a growing number of services and branching out a bit more into infrastructure I came to the realization that this isn't the best choice and I'm fully in support of boring descriptive names now.
Our services are now called scraper, proxy-manager, webrouter. This makes it a lot easier to see dependencies, figure out what an alert is for or track down issues in a large micro-service architecture where you are not always sure what a service is used for.
