In the current software eco-system, the applications are becoming more eventful and we can not trust enough traditional message-based integration concepts and technologies for system integration. Through this slide, Sagar will walk you through design considerations for event-based integrations and Azure Event Grid as technology backend for these integrations.

2. Modern computing
is all about events
@imSharmaSagar

3. Managing events is
important but cumbersome

4. What if all these events
could be managed and
directed from one place?

5. Azure Event Grid
Broad coverage within
Azure and beyond
Fully-managed
event routing
Near real-time event
delivery at scale

6. Benefits
Unlock new scenarios
for your apps
Focus on innovation
and pay per event
Ensure reliability and
performance for your apps

7. But Wait … What About?
Event Hubs
• “Point in time” data
• Fast pull
• Replay / strict ordering
• Big data streams

8. But Wait … What About?
Event Hubs
• “Point in time” data
• Fast pull
• Replay / strict ordering
• Big data streams
Service Bus
• Queue for critical items
• Routing
• Workflow
• Transactional

9. But Wait … What About?
Event Hubs
• “Point in time” data
• Fast pull
• Replay / strict ordering
Event Grid
• Business logic
• Push, not poll
• Handlers
Service Bus
• Queue for critical items
• Routing
• Transactional

10. Concepts
 Events
 Event Publishers
 Topics
 Event Subscriptions
 Event Handlers

11. Scenarios
Instantly trigger a serverless
function to run analysis when a new
file is added to a blob storage
container.
Speed up automation and simplify
policy enforcement by notifying
Azure Automation when underlying
infrastructure is provisioned.
Connects your app with other
services. Create an application topic
to route your app’s event data to
any desired destination.

22. Common Automation Scenarios with Event Grid
• When VM is deleted, remove
from monitoring system
• When resource group is created,
look up cost center for region
and add tag with number
• Grant AD group access to new
resource groups created

• When certificates are about to
expire, send email
• Respond to forwarded VM
maintenance notification
(scheduled events)
