6. Expose Web Services from/to anywhere HTTP, SOAP/HTTP, or NET.TCP Clients • Key capabilities • Relayed One-Way Unicast and Multicast • Relayed WCF NET.TCP with Direct Connect Option • Relayed WCF HTTP w/ support for REST and SOAP • Endpoint protection with Access Control • Coming soon • IIS Hybrid Cloud Bridge IIS Hybrid Cloud Bridge* WCF Plain HTTPSOAP/HTTP WCF NET.TCP

7. Relay Programming Model • WCF Programming Model • Bindings functionally symmetric with WCF • WebHttpRelayBinding (HTTP/REST) • BasicHttpRelayBinding (SOAP 1.1) • WS2007HttpRelayBinding (SOAP 1.2) • NetTcpRelayBinding (Binary transport) • Special Service Bus Bindings • NetOnewayRelayBinding (one-way) • NetEventRelayBinding(Multicast one-way) • Transport binding elements for custom bindings

8. Rendezvous (TCP & HTTP) ServiceBus sb://solution.servicebus.windows.net/a/b/ • NetTcpRelayBinding • WebHttpRelayBinding • BasicHttpRelayBinding • WS2007RelayBinding • Rendezvous Handshake • Bi-Directional • Net.Tcp Full Duplex • No message size limit BackendNaming RoutingFabric Oneway RendezvousCtrl Msg Frontend Nodes Ctrl NLB 2 3 TCP/SSL or HTTP 1 HTTP/SocketForwarder Ctrl Sender Receiver outbound socket rendezvous outbound socket connect 4

10. Using Queues R • Load Leveling • Receiver receives and processes at its own pace. Can never be overloaded. Can add receivers as queue length grows, reduce receiver if queue length is low or zero. Gracefully handles traffic spikes by never stressing out the backend. • Load Balancing • Multiple receivers compete for messages on the same queue. Provides automatic load balancing of work to receivers volunteering for jobs. • Offline/Batch • Allows taking the receiver offline for servicing or other reasons. Requests are buffered up until the receiver is available again. S R

11. Using Topics R • Message Distribution • Each receiver gets its own copy of each message. Subscriptions are independent. Allows for many independent ‘taps’ into a message stream. Subscriber can filter down by interest. • Constrained Message Distribution (Partitioning) • Receiver get mutually exclusive slices of the message stream by creating appropriate filter expressions. R true S R P > 999 and P < 1999 R ShipDestination = ‘FL’ R

12. Messages Broker Message • Brokered messaging properties are not SOAP headers • Properties are key/value pairs that may very well carry payloads • It’s not uncommon to have messages with empty message bodies • Message bodies are useful for a single opaque payload not exposed to the broker (e.g. encrypted content) Properties Value Key Value Key Value Key Value Key Body Body

13. Runtime API Choices Apps HTTPREST AMQP* WCF Service Model Messaging API NetMessagingBinding Service Bus Relay Protocol Implementation(private) .NET Framework 4.x Any Platform Service Bus

14. Lots of Fixes Based on Feedback • Configuration pattern • New constructors • Read from web/app/cloud configs • Easy to move from local project to azure hosted one • Service Bus Connection string  • Easy to plug in info into APIs thru config • IsTransientproperty on exceptions to ease retry decisions • Fixed ConnectionStatusBehavioracross all relay bindings • Disable cert revocation check

15. demo Managing Access Control Name Title Group

16. Access Control – Conceptual Model bar foo / baz owner: Sendowner: Listenowner: Manage • Each name/branch in the namespace can have a set of associated mappings from ‘claims’ to ‘rights’ • ‘Claims’ are issued by identity providers federated with Access Control • ‘Rights’ define permissions on Service Bus entities. ‘Send’, ‘Listen’, ‘Manage’ abc boo bee John: Manage pqr def Fred: SendAlice: SendPeter: Listen ghi

17. SBAzTool– Service Bus Authorization Tool • Included in the SDK samples collection • sbaztoolmakeid <id> <key> – Create a new service identity • sbaztoolshowid <id> – Show details of a service identity • sbaztooldeleteid<id> – Delete a service identity • sbaztoolgrant <op> <path> <id> – Grant right • sbaztool grant Listen /foo clemensv • sbaztool grant Send /bar fredsmith • sbaztoolrevoke<op> <path> <id> – Revoke right • sbaztoolshow <path> – Show rights on path • Sample also includes the Microsoft.ServiceBus. AccessControlExtensions reusable library

19. Pricing • $0.01 for each 10,000 messages (or ‘a buck per million’) • Fine print: • Messages up to 64KB = 1 message charge • Messages over 64KB = 1 message charge per (partial) 64KB segment • Relay HTTP request and response , 1 message per partial 64KB segment • Relay NET.TCP, 1 message per partial 64KB segment • $0.10 for each 100 Relay hours • Per indiviudual endpoint, not per connection • Up to 25 listeners (quota limit) on one endpoint, one charge • Standard Windows Azure DC egress traffic charges

20. futures IguazuEDI/EDIPortal

21. “Iguazu” • Cross-platform push notification integration for Service Bus • “Notification Topics” • New entity type alongside Queues, Topics, Relays • Same Message Format • Composition with Other Entities

22. Iguazu – Delivery Model Two-Step Registration: PNS Service Bus Events are regular Service Bus messages with properties Notification Topic Target Device App PNS Events are mapped to notifications and routed through the PNS API

23. Iguazu – Event/Notification Mapping Principles The client application stays fully in control of its experience supplying a parameterized template with each target subscription Device Notification Topic Target PNS Service Bus “fills in the blanks” by mapping incoming events to the desired per-device/per-app template.
