The image shows an architecture diagram demonstrating how Azure App Service integrates with Oracle Autonomous Transaction Processing Serverless using virtual networking.

On the left, within "Azure App Service," there is a "Scale Unit" containing three instances of "Worker Application." Each worker application is accompanied by "Oracle REST Data Service with MongoDB API," illustrating a scalable set of services.

These worker applications connect to an "Application VNet/Subnet," specifically to an "Integration subnet." At the center of the diagram, this connection is represented by a "Virtual Network Interface," which serves as the linkage between the application and database networks.

A labeled line, "VNET peering," connects the application subnet to the right side of the diagram, which is labeled "Primary Database VNet." This network contains a "Delegated subnet" that includes two components: "OCI Private Endpoint" and "Oracle Autonomous Transaction Processing Serverless."
