  3. Agenda • Connected Experiences • Live Services Communications Services • Connected data through change notification • Connected devices through seamless P2P • Connected users through presence and activities

  4. Connected Experiences • User Expectations • Integrated experiences that span devices, applications, browser-rich client • Device optimized experiences • Engineering Reality • Bootstrapping even simple scenarios is difficult • Lots of infrastructure required to get off the ground • Lack of common interoperable services • Result for users • Devices, applications and services create islands on which users must survive

  5. Getting Off The Island … • Services and devices working together to deliver connected experiences • Unlock data for anywhere access • Light up devices with consistent capabilities • Connect data and devices through services • Connectivity and communication is key • Proximity - close the gaps between data and devices • Engaging - relevant information to enliven experiences • Communication Services • Connecting devices, data and users through a consistent, approachable framework

  7. Communication Services • Powering connected experiences • Connected Data • Subscription and Change Notification Servicesto connect applications to the data that matters • Connected Devices • Overlay Communication Network and P2Pto connect devices and enable data transfer • Connected Users • Awareness and Activity Services to connect users through presence and shared activities

  8. Subscriptions and Notifications Simple … Scalable … Resilient

  9. Subscriptions and Notifications Overview Subscription Service Queue Service Fanout Subscribe Change Storage Storage Storage Resource Managers Storage Device Connectivity Others Transports Http Tcp … Live fx Notification Subscribe Devices

  10. Scale and Recovery • Notifications Scale • Horizontal scale through partitioning and instance management • Consistent hashing for resource addressing • All stored as in-memory tables, TTLs enforced • Failure Modes and Recovery • State loss – Subscription instances go down • Queue loss – Queue service instances go down • Notification service will alert and recover

  11. Lessons learned … Patch Tuesday + fixed TTLs == badness • Load on services after patch Tues • Rinse and repeat every 2hrs for Pub/Sub service
