API Control Planes and Adapter Layer Architecture
Acting as the centralized API control plane and adapter layer for Harbor modules, Harbormaster orchestrates inter-service communication and external data integrations. Harbormaster structures control plane protocols around robust Markdown specifications.
Architecture Invariants
- Centralized Control Plane Routing: Incoming service requests route through Harbormaster control nodes to validate authentication and payload schemas.
- Modular Adapter Layer Isolation: In-house and third-party modules interface with Harbormaster through standardized adapter wrappers to maintain decoupling.
- Stateless Request Handling: Control plane endpoints maintain zero persistent session state, ensuring high availability and horizontal scaling.
Robust API control planes provide a reliable backbone for interconnected digital garden services.
