Problem

We're assembling a service taxonomy from the health-check catalog, bucketing each service on what its name advertises: 'api' in the name makes it an 'api_service', 'cache' or 'redis' makes it a 'cache_service', 'db' or 'postgres' makes it a 'database', and a name matching none of those is 'other'. List each service once alongside the bucket it lands in.

Summary

The name tells you what it is. Mostly.
