# Microsoft Azure Service Bus

Microsoft Azure Service Bus is a cloud-based messaging service used to connect any applications, devices, and services running in the cloud to any other applications or services.

Use metrics from Azure Service Bus to:

* Visualize your Service Bus functionality.

* Correlate your Service Bus performance with your applications.

## Prerequisites

* Integration with Microsoft Azure, as detailed in **[Azure Metrics](https://coralogix.com/docs/integrations/azure/azure-metrics.md)**.
