Microsoft is pleased to announce that, following a six month preview period, support for OASIS Advanced Message Queuing Protocol (AMQP) version 1.0 in Windows Azure Service Bus has now transitioned to General Availability (GA). Service Bus provides a hosted, secure, and widely available infrastructure for messaging, large-scale event distribution, naming, and service publishing. Developers can now build robust, cross-platform, hybrid applications using an open, standard protocol. Applications can be constructed using components built using different languages and frameworks, and running on different operating systems. All these components can connect to Service Bus and seamlessly exchange structured business messages efficiently and at full fidelity.
