When the sender's and receiver's APIs do not match, Cloud Integration in [SAP Integration Suite](artifact:btp-integration-suite) sits between them to determine receivers, filter, map structures and convert protocols, which is the ground of [integration flows](capability:integration-flows); [SAP Connectivity service](artifact:btp-connectivity), [Cloud Connector](artifact:sap-cloud-connector) and [SAP Destination service](artifact:btp-destination) reach on-premise receivers, and the edge integration cell runtime keeps processing inside a customer-managed landscape where compliance requires it. Direct exchange without middleware is allowed when the two APIs already align, asynchronous communication is the default the page states, and it is drawn at the level of the pattern, following SAP's Integration Solution Advisory Methodology, without designing any one flow.","short":"Near real-time messages between business applications","authors":["actor:sap-architecture-center"],"published":"2024-08-01","sources":[{"url":"https://raw.githubusercontent.com/SAP/architecture-center/main/docs/ref-arch/RA0021/readme.md","title":"RA0021 readme.md in SAP/architecture-center","checked":"2026-09-15","quote":"For unaligned APIs between sending and receiving solutions (Cloud2Cloud, Cloud2OnPremise), the Cloud Integration capability within SAP Integration Suite applies mediations (e.g., receiver determinations, filtering) and transformations (e.g., structure mappings, protocol conversion)."},{"url":"https://raw.githubusercontent.com/SAP/architecture-center/main/docs/ref-arch/RA0021/readme.md","title":"RA0021 readme.md in SAP/architecture-center","checked":"2026-09-15","quote":"Direct message exchange is possible when the outbound API of the sender and the inbound API of the receiver are aligned."},{"url":"https://raw.githubusercontent.com/SAP/architecture-center/main/docs/ref-arch/RA0021/readme.md","title":"RA0021 readme.md in SAP/architecture-center","checked":"2026-09-15","quote":"For data compliance and governance requirements, the edge integration cell runtime enables processing data locally within customer-managed private landscapes."}],"drafted_with_ai":true,"provenance":{"discovered_via":[{"source":"source:curator"}],"first_seen":"2026-09-15"},"published_on":"source:architecture-center"},"readings":{"liveness":[{"label":"Checked against the source","tier":"unknown","evidence":"nobody has checked it"},{"label":"Source reachable","tier":"good","evidence":"up as of 2026-10-26"},{"label":"Source updated","tier":"good","evidence":"2026-10-09 by the publisher"}],"compatibility":[{"label":"Version","tier":"unknown","evidence":"no version declared"},{"label":"Moved since?","tier":"good","evidence":"no recorded change after 2024-08-01"},{"label":"Findings","tier":"good","evidence":"none flagged"}],"reach":[{"value":null,"unit":"views"},{"value":null,"unit":"comments"},{"value":null,"unit":"likes"}]},"signals":{"crawled_at":"2026-10-26","reachable":true,"source_updated":"2026-10-09"},"series":null,"edges":{"authors":[{"ref":"actor:sap-architecture-center","name":"SAP Architecture Center","json":"/actors/sap-architecture-center.json"}]}}
