Microsoft Azure Service Bus provides a hosted, secure, and widely available infrastructure for widespread communication, large-scale event distribution, naming, and service publishing. Endpoints can be located behind network address translation (NAT) boundaries, or bound to frequently-changing, dynamically-assigned IP addresses, or both. Service Bus comes with a 99.9% uptime SLA.
Microsoft Azure Service Bus provides a hosted, secure, and widely available infrastructure for widespread communication, large-scale event distribution, naming, and service publishing. Service Bus provides connectivity options for Windows Communication Foundation (WCF) and other service endpoints – including REST endpoints -- that would otherwise be difficult or impossible to reach. Endpoints can be located behind network address translation (NAT) boundaries, or bound to frequently-changing, dynamically-assigned IP addresses, or both.
Service Bus provides both “relayed” and “brokered” messaging capabilities. In the relayed messaging pattern, the relay service supports direct one-way messaging, request/response messaging, and peer-to-peer messaging. Brokered messaging provides durable, asynchronous messaging components such as Queues, Topics, and Subscriptions, with features that support publish-subscribe and temporal decoupling: senders and receivers do not have to be online at the same time; the messaging infrastructure reliably stores messages until the receiving party is ready to receive them.
Runs anywhere, connects nearly anything
Azure Service Bus is a generic, cloud-based messaging system for connecting just about anything—applications, services, and devices—wherever they are. Connect apps running on Azure, on-premises—or both. You can even use Service Bus to connect household appliances, sensors, and other devices like tablets or phones to a central application or to each other.
Build robust cloud solutions that scale to meet demand
Asynchronous messaging patterns are the architectural cornerstone of reliable and scalable applications. Integrating cloud resources like SQL Azure, Azure Storage, and Azure Websites with Service Bus messaging ensures smooth operation under heavy and variable load with the durability to survive intermittent failures.
Manage message delivery in the cloud
Queues offer simple first in, first out guaranteed message delivery and supports a range of standard protocols (REST, AMQP, WS*) and APIs. Topics deliver messages to multiple subscriptions and fan out message delivery at scale to downstream systems.
Connect on-premises applications to the cloud
Service Bus Relay solves the challenges of communicating between on-premises applications and the outside world by allowing on-premises web services to project public endpoints. Systems can then access these web services, which continue to run on-premises from anywhere on the planet.
