BizTalk L3 Component Diagram Example

This BizTalk component diagram is the L3 view of the BizTalk example set. It zooms into the runtime from the L2 Container example and models realistic BizTalk artifacts in layered responsibilities.

The layers show how messages move from inbound receive ports through orchestration and mapping to outbound send ports. Copy the C4Component markup below and follow Import Your First C4 Diagram to import it into a C4 Diagram Set; L3 Component nodes bind to Integrations and Container nodes to Services in your Repository Model. See C4 Diagrams for the concepts.

Component Type Highlights

  • Receive Layer: Receive Port components
  • Processing Layer: Orchestration components
  • Mapping Layer: Canonical Mapping components
  • Delivery Layer: Send Port components
  • Monitoring Component: Tracking Store

Import-Friendly Notes

  • Layer boundaries (Container_Boundary) provide stable domain-like grouping for repository entry creation.
  • Service-level capabilities use Container(...) (not Component(...)) so import can map them as Services instead of Integrations.
  • Consistent naming across BizTalk and Migration sets improves cross-diagram matching after import.
