service-registry

Multi-tenant service integrations can be structured using a three-layer model that separates service type, adapter, and instance. This separation enables runtime swapping of service implementations and ensures per-tenant isolation through a registry-driven resolution process.

To register a new external service across tenants, define a service type for the capability, implement an adapter for the provider, and configure a deployment instance. This pattern ensures consistent naming, schema validation, and predictable integrations.

Resolver functions in a service registry modify the service resolution flow to dynamically route requests to the correct adapter and instance. They ensure per-tenant isolation by validating configuration schemas against registered registry entries during the lookup process.

No specific external dependencies or components are required to implement this multi-tenant integration pattern. The model relies entirely on defining internal config schemas, resolver functions, and adapter implementations within your existing platform environment.

You should separate service type, adapter, and instance when you need to scale cross-tenant integrations and add new providers dynamically. This architecture clearly distinguishes between capability, implementation, and configured deployment to reduce integration risk.

A registry-driven resolution process is used to enforce consistent naming conventions and schema validation across multiple tenants. It provides a repeatable pattern for managing the lifecycle of external services and seeding new instances predictably.
