This module translates the design patterns and architectural principles from Module 2 into executable, production-ready code. You'll build the core components that enforce governance and ensure reliability at the integration layer.

The focus is hands-on implementation: constructing a policy-aware gateway, developing reliability controls such as retry envelopes and circuit breakers, and assembling the tooling stack needed to deploy and manage integrations safely. You'll leave with deployable code and a clear path from prototype to governed production system.
