Core Service

Definitions

1. A service that plays a central role in a platform and is widely depended on by other services, jobs, or customer-facing features. Core services usually require stronger reliability guarantees because their failure cascades broadly.

   In plain English: A key backend service that many other systems rely on.

   Example: "Identity was treated as a core service, so every schema change there went through extra compatibility and rollback review."
