Deeper dive
The win was social as much as technical: one catalog of APIs meant fewer surprises when onboarding partners or internal consumers.

Enterprise API Governance Mesh — One Control Plane, Many Teams
Central policies for rate limits, auth scopes, and audit trails across dozens of internal APIs—without slowing product squads.
Project overview
Problem
Each product team shipped APIs with different auth patterns and logging gaps. Risk and platform teams could not answer who called what, or enforce limits consistently.
Solution
A thin mesh layer at the edge applies JWT validation, scope checks, quotas, and structured audit events. Teams keep their stacks; the plane owns cross-cutting rules.

System architecture
Envoy-style sidecars and a central policy registry. OPA-style bundles version policies; changes roll out gradually per route group with automatic rollback on error budgets.
Workflow
Register service
OpenAPI or gRPC descriptors imported; default policies attach by domain.
Policy draft
Security proposes changes in a branch; simulation shows blast radius on traffic mirrors.
Approve & promote
Dual control for production; canaries on read-only checks first.
Observe
Dashboards tie violations to owning teams with SLA-style follow-up.
Results & impact
Auditors got consistent evidence. Product teams stopped reinventing auth middleware and focused on business logic—governance became a service, not a meeting series.
