Messaging services on Azure

Connect your modern applications—written in different languages and hosted anywhere—with a comprehensive set of messaging services on Azure.

Reliably connect hybrid applications using messaging services

Messaging services on Azure provide the interconnectivity between components and applications that are written in different languages and hosted in the same cloud, multiple clouds, or on-premises. Use message queues or topics to send messages without concerns of consumer availability and to help balance varying workload throughput.

Easily migrate your on-premises enterprise messaging solutions to the cloud using common industry and open-protocol support such as ISO/IEC Advanced Message Queuing Protocol (AMQP) and Message Queuing Telemetry Transport (MQTT).

Meet the demands of your growing business by using scalable messaging services on Azure. Ingest millions of messages and events without concerns about infrastructure management or operations.

Continue to access on-premises and multicloud resources with direct connectivity through firewalls, without compromising security. Messaging services on Azure support hybrid connectivity by originating requests from the consumer.

Build modern reactive microservices with events coming from Azure or from your own applications. Reduce time and complexity with event-driven applications, which only execute when events are pushed to the serverless component.

Customers are doing great things with messaging services on Azure


"The solution needed to be simple. The ZEISS team did not want to add to the complexity faced by the users of their highly advanced devices. Yet the small development team wanted to work quickly, so they created an Enterprise Service Bus in the cloud, capable of integrating the various devices and customer touch points via standard REST-based APIs."

Frequently asked questions

  • Messages carry intent or transfer the state between components, while events are observations about what has happened. Learn more.
  • A message queue provides an asynchronous FIFO (first-in, first-out) point-to-point communication channel. While topics also allow you to do asynchronous FIFO communication, topics also allows producers to publish messages that can then be subscribed to by one or more consumers.
  • Event distribution provides the distribution of discrete events. A discrete event describes a specific action that has taken place by the publisher. Event streaming carries informational data points as elements of a continuously published stream.
