relay programming model
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

using queues
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

using topics
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.

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)

lots of fixes based on feedback
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
access control conceptual model
Access Control – Conceptual Model

bar

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’

pricing
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
iguazu
“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

PNS

Events are mapped to notifications and routed through the PNS API

iguazu event notification mapping principles
Iguazu – Event/Notification Mapping Principles

The client application stays fully in control of its experience supplying a parameterized template with each target subscription

PNS

Service Bus “fills in the blanks” by mapping incoming events to the desired per-device/per-app template.
