Simplify enterprise cloud messaging

Depend on Service Bus when you need highly reliable cloud messaging service between applications and services even when they’re offline. Available in every Azure region, this fully managed service eliminates the burdens of server management and licensing. Get more flexibility when brokering messaging between client and server with asynchronous operations along with structured first-in, first-out (FIFO) messaging and publish/subscribe capabilities.

Build scalable cloud solutions

Leverage the power of asynchronous messaging patterns to reliably scale your enterprise applications. Integrate cloud resources such as Azure SQL Database, Azure Storage, and Web Apps with Service Bus messaging to get smooth operation under variable loads and the durability to survive intermittent failures.

Implement complex messaging workflows

Improve availability by building messaging topologies with complex routing. Use Service Bus to deliver messages to multiple subscribers and fan out message delivery at scale to downstream systems.

Enable your existing Java Message Service (JMS 2.0) applications to talk to Service Bus over AMQP

Get a fully managed enterprise messaging service with native JMS support without worrying about licenses and operational costs of running your messaging broker in an on-premises or infrastructure as a service (IaaS) environment.
