6. - CollectionProducers Your are here Massively Parallel Azure Systems w/ Jason Young Tuesday@10:30am, Aralia HDInsight and Internet of Things w/ Tony Guidici Tuesday, 2:30pm, Tamarind

8. Guaranteed FIFO, with push-style API, up to 80GB maximum size, 10,000 queues per namespace, 2,000 messages per second, 256KB per message.

9.  Express Decreases latency by storing the messages in memory  Partitions Managed scale out (at max 16x)

10. A higher level abstraction from queues, enables pub/sub models with similar scale out capabilities and consistent pricing

11.  Filters Allows subscribers to selectively receive messages  Rules Aid in filtering and authorization  Volatile Subscribers Can delete on idle, allowing for transient consumers

14. Event Sources Cloud Services Storage & Analytics Custom Code & 3 rd Party Services Web/Mobile User Interfaces Integration Services Event Hub - Hyper Scale - - Fully Managed - - Interoperable - - Secure - - Cost Effective -

15. Event Hub Publisher concept  Every Event Hub has pre-defined number of partitions  Every event has a partition key => mapped to one of the partitions Partition 1 Partition 2 Partition “n” Event 1 PartitionKey=A Event 1 PartitionKey=B

17. Critical to scaling
