SAP BTP for Application Integration

Main CLOUD-Component is SAP Integration Suite with the following main services

  • SAP Cloud Integration (f.k.a. CPI / HCI)
  • SAP API Management
  • SAP Open Connectors
  • SAP Integration Advisor
  • SAP Event Mesh (f.k.a. Enterprise Messaging) is currently not part of the core offering which is bundled as well under the name Integration Suite)
  • SAP Data Intelligence
  • check out SAP Discovery Center for the complete list of services related to SAP Integration Suite

Main ON-PREMISE-Component is (still) SAP Process Orchestration with

  • SAP Process Integration / Advanced Adapter Engine Extended
  • SAP PI B2B-Addon (for EDI-based communication)
  • SAP Cloud Integration Runtime
  • SAP Business Process Management (BPM) & SAP Business Rules Management (BRM) for stateful message processing and user interaction (task management)
  • …waiting for the Integration Cell (in 2022?) to take over the on-premise runtime of the Integration Suite and replacing SAP Process Orchestration…
