  19. 19. Why is Event Grid different? • Cloud Native by design • Which makes it serverless friendly • Engineered for reliability and scale • Supports CNCF Cloud Events v0.1
  20. 20. Cloud native by design • Always available (99.99% SLA) • Near real-time event delivery (<1s e2e) • At least once delivery • Dynamic scale • 10,000,000 events per second per region • 100,000,000 subscriptions per region • Platform agnostic (WebHook) • Language agnostic (HTTP protocol)
  21. 21. Serverless friendly • Ease of setup from the Portal • Azure CLI • Powershell
  22. 22. Engineered for scale and reliability • Cascading log architecture keeps hot path clear Cascading retry logs Replicated Log 10 sec 1 min 1 hr Event Grid Cluster
  23. 23. Engineered for scale and reliability • Cascading log architecture keeps hot path clear • Each clusters has all subscriptions • Nodes can be added to or removed from cluster Event Grid Cluster
  24. 24. Engineered for scale and reliability • Cascading log architecture keeps hot path clear • Each clusters has all subs • Nodes can be added to or removed from cluster • Clusters can be added 1 min Event Grid Cluster 1 1 min Event Grid Cluster 2

US WestUS East Engineered for scale and reliability • Cascading log architecture keeps hot path clear • Each clusters has all subs • Nodes can be added to or removed from cluster • Clusters can be added • Traffic spans regions Event Grid Cluster R1C1 Event Grid Cluster R1C2 Event Grid Cluster R2C1
  26. 26. Engineered for scale and reliability • Retry intervals • 10 seconds • 30 seconds • 1 minute • 5 minutes • 10 minutes • 30 minutes • 1 hour • Once an hour up to 24 hours • Defaults: 30 delivery attempts / 24 hours
  27. 27. Engineered for scale and reliability • Dead-lettering • Requires Storage account + container • Dead-lettered events stored as blobs

  29. 29. What is CNCF CloudEvents? • Event Protocol Suite developed in CNCF Serverless WG • Common metadata attributes for events • Flexibility to innovate on event semantics • Simple abstract type system mappable to different encodings • Transport options • HTTP(S) 1.1 Webhooks, also HTTP/2 (v0.1) • MQTT 3.1.1 and 5.0 (draft) • AMQP 1.0 (draft) • Encoding options • JSON (v0.1, required for all implementations) • Extensible for binary encodings: Avro, MessagePack, AMQP, etc.
  30. 30. CloudEvent Schema v0.1
  31. 31. Ubiquitous • Today there are 10+ publishers • By year end most Azure services will be publishers • Then most Microsoft services • Expect industry to embrace Cloud Events • Grid will be coming to IoT Edge • And beyond…
  32. 32. How Event Grid is sold • Publish is an operation • Delivery attempt for each destination is an operation • Advanced matching (filtering) is an operation
  33. 33. How Event Grid composes with Queues and Streams • Other messaging services can be publishers or subscribers to Event Grid • Sometimes you want WebHook • Sometimes Queue • Others Stream • Why: at high scale a queue or log can work better • Grid will give you all of them sub1 sub2 mytopic Storage queue Event Hubs
  34. 34. Security and Authentication • Validation Handshake (WebHook event delivery) • Event of type Microsoft.EventGrid.SubscriptionValidationEvent • With validation data • Prove • Echo back {validationCode: “value”} • Send GET to validationURL
  35. 35. Security and Authentication • Topic publishing • “aeg-sas-key” header • “aeg-sas-token” header
