Azure Service Bus Description
Service Bus is the best cloud messaging service for applications and services that are offline. This fully managed service is available in every Azure region and eliminates the hassles of licensing and server management. Asynchronous operations allow for greater flexibility in brokering messaging between client-server with structured first-in-first-out (FIFO), messaging, and publish/subscribe capabilities. To scale your enterprise applications reliably, you can leverage the power of asynchronous messages patterns. Integrate cloud resources like Azure SQL Database, Azure storage, and Web Apps to ensure smooth operation under variable loads. This will also give you the resilience to endure intermittent failures. Complex routing can improve availability. Service Bus allows you to send messages to multiple subscribers, and to spread message delivery to downstream systems.
