Modern Systems Integration Patterns

Systems integration remains one of the most challenging aspects of enterprise architecture. As organizations adopt more diverse technology stacks, the need for robust integration patterns becomes critical.

Event-Driven Architecture

Event-driven patterns enable loose coupling between systems. Rather than direct synchronous calls, systems communicate through events, allowing for greater resilience and scalability.

API Gateway Patterns

API gateways serve as the entry point for all client requests. They handle cross-cutting concerns like authentication, rate limiting, and request routing.

Message Queues and Streaming

Message queues provide reliable asynchronous communication. Streaming platforms enable real-time data processing across system boundaries.

Best Practices

• Define clear contracts between systems
• Implement idempotency for all integration points
• Plan for versioning from the start
• Monitor integration health continuously
