This document provides an overview of Windows Azure Service Bus including: - How it provides brokered messaging with queues and topics as well as relays for synchronous communication. - How it uses AMQP 1.0 as a messaging protocol and supports multiple languages and platforms. - How Notification Hubs can be used to send push notifications to multiple client platforms.

• Include in CLASSPATH
• Built Using Eclipse

26. • Download from
http://qpid.apache.org/proton/download.html
• Python
• PHP
• Deployed on Linux VM in Windows Azure IaaS
• Built Using Make

29. • One-Time Set Up
• Create a Notification Hub in Service Bus
• It contains the credentials required by the Platform
Notification Service (PNS)
• Register
• The client app retrieves its current handle from the PNS
• Client app creates (or updates) a registration on the
Notification Hub with the current handle
• Send Notification
• The app back-end sends a message to the Notification Hub
• Notification Hub pushes it to all PNS
