After this we are left with Event Grid, let us see what this feature offers in Azure.

You can easily create event-driven applications using Microsoft Azure’s fully managed event routing service, Azure Event Grid. By offering a unified event routing system, it streamlines the process of responding to events from various Azure services, custom applications, or external sources. Here are some essential Azure Event Grid characteristics and ideas:

1. Events: Events are a specific instance of something occurring in Azure or somewhere else. These can be custom events produced by your application, such as the creation of a virtual machine, the uploading of a file to a storage account, etc.

2. Publishers Services or resources that emit events are known as publishers. Custom applications and Azure services like Azure Storage, Azure Service Bus, Azure Event Hubs, and Azure Storage can publish events to Event Grid.

3. Event Subjects In essence, event topics are the endpoints or channels that receive and route events. In Event Grid, you define the events you want to handle within event topics. For each event topic, you can have one or more subscribers.

4. Subscribers The parts or endpoints that watch for events coming from Event Grid are known as subscribers. Webhooks, Azure Event Hubs, Azure Functions, Azure Logic Apps, and other components can all be subscribers. When they reach the designated endpoint, these subscribers respond to events.

5. Subscription to an Event: A rule that specifies how events should be forwarded to a particular subscriber is known as an event subscription. You can specify the destination for those events and filter events based on the type of event or other attributes.

6. Dead lettering: Support for dead-lettering means that an event can be put in a dead-letter queue for diagnostic purposes if it cannot be delivered to a subscriber using Event Grid.

7. Retry Guidelines: Retry mechanisms are included in Event Grid to guarantee event delivery to subscribers. Event Grid will make another attempt to deliver the event in accordance with a specified retry policy if a subscriber is momentarily unavailable.

8. Customized Events: Event Grid is a flexible solution for managing events generated by your applications because it allows you to send custom events in addition to the built-in events that Azure services can generate.

Building event-driven architectures, serverless applications, and decoupling different distributed system components are all possible with Azure Event Grid. It’s a crucial element for creating scalable, responsive applications that respond to changes and real-time events in Azure and elsewhere.

Now, in summary, we can jot down a few specifics that are commonly used, and more importantly how all these services are used collectively.
