The image shows a high-level architecture diagram integrating Microsoft Azure and Oracle Cloud Infrastructure (OCI) services across two Azure regions.

• On the left, "Users" are shown connecting through "Azure Front Door" to a "Web Application Firewall".
• Data flow continues into two horizontally-aligned sections, labeled "Azure Region 1" (top) and "Azure Region 2" (bottom).
• Both regions contain the following text blocks:
  • "Subscription"
  • "Availability Zone 1"
  • Within each, "Application VNet/Subnet" (with "Integration subnet" inside), leading to an icon labeled "App Service".
  • "VNET peering" is indicated by arrows between the App Service and the next section, labeled "Primary Database VNet" (with a nested "Delegated subnet"), which contains icons for "OCI Private Endpoint" and "Oracle Autonomous JSON Database".
• To the right of each region, arrows labeled "Automatic backup" (top) and "Backup based peer" (bottom) point to a service in a grey box, labeled "OCI Services" and "OCI Object Storage".
