Problem

The platform catalog needs a service taxonomy. Classify each service: 'api_service' if the name contains 'api', 'cache_service' if it contains 'cache' or 'redis', 'database' if it contains 'db' or 'postgres', and 'other' for everything else. Each service should appear only once. Show the service name and its category, limited to the first 100 results.

Summary

The name tells you what it is. Mostly.
