1. Ashish Chhabria Program Manager - Microsoft Service Bus update

2. What is Service Bus? • Fully managed PaaS offering - “Enterprise Messaging as a Service”. • Point to Point (Queue) and Pub-Sub (Topic-Subscription) semantics. • Central arbiter of state / truth of transition or ownership. • You know the nouns: • Who is sending the message? • What is the message? • Where is the message being sent?

3. Service Bus - Queues • Sender sends message to queue • Queue ACKs receipt • Receiver connects to queue & retrieves message • Receiver ACKs complete (or other action) Sender Receiver Queue

4. Service Bus - Topics & Subscriptions • Sender only knows about Topic • Receivers only know about Subscriptions • Filters and Actions exist on Subscriptions Filter Subscription 1 type=quote type=order “type” = “order” Topic “type” = “quote” Subscription 2 Filter
