This document discusses hybrid connectivity with Windows Azure, specifically focusing on integration and messaging capabilities. It provides an overview of AppFabric and Service Bus features like queues, topics, subscriptions, filters and sessions. It also reviews the different runtime API choices and use of the BrokeredMessage class in .NET applications. A demo is planned to showcase service bus tracing, transactions, large messaging with sessions and publish/subscribe patterns.

10. queues hybrid connectivity with windows azure 10 Reliable, durable storage – up to 1GB per Queue (100Mb in CTP) Queues stay in the system once created, no TTL limit Max message size 256KB, Sessions allow grouping Messaging API, WCF, and HTTP/REST Interfaces Advanced messaging capabilities Consumer Consumer publisher queue Consumer

11. sessions Creating session-full queuenew QueueDescription {RequiresSession = true}; Defining session, when sending message message.SessionId = sessionId; Receiving messages from session SessionReceiver rcv = queueClient.AcceptSessionReceiver ("MySession", ReceiveMode.PeekLock, newTimeSpan(0,0,10)); Session session = rcv.Session; hybrid connectivity with windows azure 11

12. topics & subscriptions hybrid connectivity with windows azure 12 All the Features of Queues + Publish/Subscribe Up to 2000 Subscriptions on a Topic Each Subscription is a virtual queue getting message copies Subscriptions can have filters and actions Receiver Receiver publisher topic rules & filters Receiver subscriptions

13. filters & actions Filter conditions operate on message properties and are expressed in SQL’92 syntax InvoiceTotal > 10000.00 OR ClientRating <3 ShipDestCtry = ‘USA’ AND ShipDestState=‘WA’ LastName LIKE ‘V%’ Filters actions may modify/add/remove properties as message is selected SET AuditRequired = 1 hybrid connectivity with windows azure 13

16. the BrokeredMessageclass message body (content) can be generic (untyped) can be serialized (using generic class) object can be empty (properties only – typical for triggers) message properties (context) used for routing/filtering and metadata contains session, correlation and message id information hybrid connectivity with windows azure 16
