Standard
Integration Architecture Standard
This standard governs the architecture of system-to-system integration: the patterns used, the transports selected, the contracts established, and the operational characteristics required. It complements the API design standard (which governs synchronous request-response contracts) and the data architecture standard (which governs data flow) by addressing the architectural choices that determine how systems communicate over time.
