Integration Patterns.
Design integration architectures for multi-domain support.
Multi-domain integration requires shared components (efficiency) and domain-specific components (customization). Design clear boundaries between them.
Shared services: authentication gateway, logging infrastructure, monitoring. Domain-specific: business logic, data stores, compliance controls.
API design should be domain-agnostic where possible, with domain-specific extensions where needed. This enables shared SDKs and documentation.
SHARED GATEWAY
Common API gateway with domain routing. Unified authentication, rate limiting, and logging.
DOMAIN ROUTING
Route requests to domain-specific backends based on context. Isolation with shared infrastructure.
SHARED OBSERVABILITY
Common monitoring and logging infrastructure. Domain-specific dashboards and alerts.
DOMAIN ISOLATION
Separate data stores and processing for domain-specific requirements. Clear compliance boundaries.
