Depend on Azure Service Bus when you need highly-reliable cloud messaging service between applications and services, even when one or more is offline. Available in every Azure region, this fully-managed service eliminates the burdens of server management and licensing. Asynchronous operations enable flexible, brokered messaging between client and server, along with structured first-in-first-out (FIFO) messaging and publish/subscribe capabilities—perfect for tasks such as order processing.
The cornerstone of durable applications, asynchronous messaging patterns give you the power to scale reliably. When you integrate cloud resources such as Azure SQL Database, Storage, and Web Apps for App Service with Service Bus messaging, you get smooth operation under variable loads, plus the durability to survive intermittent failures.
Build durable messaging topologies with complex routing while increasing overall availability. Use Service Bus to deliver messages to multiple subscribers and fan out message delivery at scale to downstream systems.
Securely access existing assets—wherever they are—without complex firewall, network, or VPN configuration using the hybrid connections feature within Service Bus Relay. These services provide enhanced authentication and connectivity through the cloud, plus the ability to view and monitor activity.
