# Azure Database and Messaging Services

## Overview{% #overview %}

Datadog APM uses **inferred spans** to collect traces and trace metrics from Azure Cosmos DB, Event Hubs, and Service Bus. Inferred spans appear automatically in flame graph and waterfall views for Datadog-instrumented services running on Azure. No additional configuration is required. To set up instrumentation for Azure Serverless workloads, see [Serverless Monitoring](https://docs.datadoghq.com/serverless.md).
