Create an Azure private order processing architecture. A public client enters through Front Door and API Management to an App Service API. The API reads and writes Azure SQL through a SQL private endpoint and enqueues work in Service Bus. A Function worker consumes Service Bus work, writes files through a Storage private endpoint, and writes order status to the Azure SQL database through the shared SQL private endpoint. The API and Function read Key Vault and emit telemetry to Azure Monitor. Service Bus work that reaches its retry limit moves to a dead-letter queue; an operations client inspects the DLQ and triggers redrive back to the work queue. Show API and Function VNet integration in an application subnet, and place private endpoints in a data subnet. SQL, Storage, Service Bus, Key Vault, and Monitor are managed services outside the VNet but within one subscription, region, and resource group. Show private endpoint relation direction explicitly. Add no other services.
