The average enterprise operates with 175+ software applications. Connecting these systems is one of the most significant technical challenges IT leaders face today.

Core Principles of Integration Architecture

  • Loose Coupling: Use event-driven patterns to avoid deep dependencies between systems.
  • Idempotency: Integration endpoints should handle duplicate requests gracefully.
  • Observability: Every integration must be monitored — silent failures are the most dangerous.
  • Versioning: API contracts must be versioned with proper deprecation windows.

Security Considerations

OAuth 2.0, API key rotation, rate limiting, and audit logging are baseline requirements. Every API integration is a potential attack surface.
