BizTalk L2 Container Diagram Example

This BizTalk container diagram is the L2 view of the BizTalk example set. It zooms into BizTalk Server from the L1 Context example and highlights the common runtime building blocks and message flows.

The goal is architectural clarity: how Receive Locations, Orchestrations, Send Ports, Rules, and databases collaborate. Copy the C4Container markup below and follow Import Your First C4 Diagram to import it into a C4 Diagram Set; L2 Container nodes bind to Services (or to Systems for platforms such as the Portal), and each Boundary can bind to a Domain. See C4 Diagrams for the concepts.

Component Type Highlights

  • Integration runtime components: Receive Locations, Orchestrations, Send Ports
  • Data components: MessageBox Database, Tracking Database, SQL Server
  • File integration component: File Share

Import-Friendly Notes

  • ContainerDb is used for SQL-backed stores so import can suggest Database-oriented container types.
  • Integration technologies are explicit (for example XSLT, BRE, SOAP, REST, SFTP) to improve classification hints.
