Event Hubs supports AMQP over Web Sockets
Updated: July 14, 2015
Azure Event Hubs, the cloud-scale telemetry ingress service, has added support for Advanced Message Queuing Protocol (AMQP) over Web Sockets for customers who cannot use standard AMQP ports because of network restrictions. This works for both send and receive operations. You can find more details here: Service Bus, Event Hubs, and Web Sockets.
