Creating an event grid topic

There are different forms of event grids within Azure. We will start by creating an event grid topic service. This is an event grid that can use topics. A topic is a way of creating collections with similar types of events. The event grid allows you to subscribe to a certain topic to receive those events. There are two types of topics. System topics are built-in topics specifically used by Azure Services, such as Azure Service Bus. It is also possible to create custom topics. This allows us to structure events based on categories when you have a large enterprise system that contains a lot of events streaming through the solution. Execute the following steps, as shown in the following screenshot:

1. Open the Azure portal and go to Create a resource.
2. Search for Event Grid topic in the search field.
3. Press the Create button:
