Paul and Buzco get into the architecture of integrations: sync patterns, idempotency, error recovery, and the diagrams that keep a multi-system design comprehensible. Includes a reference diagram.

Good integration architecture is invisible; bad architecture is a 2am page. Paul and Buzco cover the patterns that make multi-system integrations reliable and maintainable, and share a reference architecture diagram you can adapt.

“Idempotency is the unglamorous hero of integration architecture.”
— Buzco Stanislav
Full transcript
Paul: Every integration eventually fails partway through. The network blips, a system is down, a payload is malformed. The question isn't whether it happens, it's whether your architecture handles it gracefully.
Buzco: Which is why idempotency is the unglamorous hero of this whole topic. If you can safely retry any operation, half your failure modes just stop being scary.
Paul: And event-driven beats brittle real-time syncs more often than people expect. Decouple the systems, let them catch up, and you stop building a house of cards.
Buzco: The diagram matters too. If you can't draw the integration on one page, nobody on the team truly understands it, and that's its own kind of risk.
