BizTalk L1 Context Diagram Example

This BizTalk context diagram is the L1 view of the BizTalk example set. It represents a typical BizTalk-era integration landscape around Order-to-Cash: the business systems stay stable, and BizTalk Server acts as the canonical integration hub between them and the external parties.

To try it in Nodinite, copy the C4Context markup below and follow Import Your First C4 Diagram to create a C4 Diagram Set, import the markup, and bind each node to a System in your Repository Model. See C4 Diagrams for the concepts.

Import-Friendly Notes

  • Uses explicit Person_Ext and System macros for better actor/system shape mapping.
  • Uses business-domain names reused across BizTalk, Azure, and Migration sets for easier matching.
