Azure Event Grid
Routes discrete Azure and custom events to handlers using subscriptions and filters
Why learn Azure Event Grid?
Teams use Azure Event Grid to adopt event routing without building the complete underlying platform themselves.
The problem it solves
Matches service events to destinations using managed rules and filters
Where it came from
Azure Event Grid is Microsoft Azure's offering for event routing. Its closest catalog counterparts are Amazon EventBridge and Google Cloud Eventarc; they address the same broad need but are not feature-for-feature identical.

Real World Example
Decoupled Inventory Synchronization
Retailers managing multi-channel inventory across disparate systems.
The business problem
Monolithic systems struggle with latency when updating stock levels across web, mobile, and physical store databases, leading to overselling.
How this topic solves it
Azure Event Grid routes discrete inventory change events to specific handlers, allowing independent services to react to stock updates without direct coupling.
- Define a custom event schema for inventory updates.
- Create an Event Grid topic to act as the entry point for events.
- Configure event subscriptions with filters to target specific product categories.
- Map event handlers to downstream services like database update functions or notification APIs.
Flow of inventory data from source to multiple reactive consumers.
Message Broker
Consumer 1
Consumer 2
- Inventory System → Publishes Event → Event Grid Topic
- Event Grid Topic → Routes Filtered Event → Web Store Handler
- Event Grid Topic → Routes Filtered Event → Mobile App Handler
Expected business outcome
Improved system responsiveness and reduced synchronization errors by decoupling event producers from consumers.
Limitations and checks
Event delivery is asynchronous, which may introduce slight delays in state consistency; verify by checking the event delivery status in the portal.
