Event Grid update

2. When should you use Event Grid?

3. Event Grid is a PubSub system
Broadcasts events
Past tense statements

4. Event Grid has Event Sources…
Push events to topics for broadcast
Don’t care about who is listening

5. …and Event Handlers (sinks)
Aware of the publisher
Responsible for reacting to events

6. A request response system
Event Grid is NOT
A request response system
A log or ledger
(But it can play a part in each)

7. Event Sources Event Handlers Event Grid Serverless Code

8. What’s new with Event Grid?

9. Service Bus as an Event Handler (Preview)
Native Service Bus integration with the Azure Platform:
Only Service Bus Queues supported initially
Azure Maps
Service Bus
Checkout-free shopping
Blob Storage
Service Bus
Process Checks

10. 1 MB Events (Preview) Send full context, always
Don’t perform GET after every event
Events over 64 KB charged in 64 KB chunks

11. IoT Hub device telemetry events (Preview)
[{ "id": "9af d40-fe2g-8b2a-bab65e106785", "topic": "/SUBSCRIPTIONS/<subscription ID>/RESOURCEGROUPS/<resource group name>/PROVIDERS/MICROSOFT.DEVICES/IOTHUBS/<hub name>", "subject": "devices/LogicAppTestDevice", "eventType": "Microsoft.Devices.DeviceTelemetry", "eventTime": " T20:58:30.48Z", "data": { "body": { "Weather": { "Temperature": 900 }, "Location": "USA“ "properties": { "Status": "Active“ "systemProperties": { "iothub-content-type": "application/json", "iothub-content-encoding": "utf-8", "iothub-connection-device-id": "d1", "iothub-connection-auth-method": "{\"scope\":\"device\",\"type\":\"sas\",\"issuer\":\"iothub\",\"acceptingIpFilterRule\":null}", "iothub-connection-auth-generation-id": " ", "iothub-enqueuedtime": " T20:58:30.48Z", "iothub-message-source": "Telemetry“ } "dataVersion": "", "metadataVersion": "1“ }]

12. GeoDR GA Metadata RPO: Zero minutes of topics & subscriptions lost.
Metadata RTO: 60 minutes till new CRUD operations.
Data RPO: Five minutes of events jeopardized.*
Data RTO: 60 minutes for new traffic to flow.**
<topic-endpoint>/api/health

13. Advanced Filters GA
Filter as many layers deep as you need "filter": { "advancedFilters": [ { "operatorType": "NumberGreaterThanOrEquals", "key": "Data.Key1.Key2.Key3", "value": 5 }, { "operatorType": "StringContains", "key": "Subject", "values": ["container1", "container2"] } ]
String, Numerical, and Bool operators

14. Event Domains GA 100,000 topics per Event Domain
100 Event Domains per Azure Subscription
50 ‘firehose’ event subscription at the Domain scope

15. What is an Event Domain?

16. Event Domains are a management construct
Manage all your topics in one place
Set fine-grain auth rules for each topic
Publish all of your events to one endpoint
