Azure Event Grid and reactive architecture

When working with multiple services in the cloud, you often need to have a centralized service responsible for routing events to a different endpoint. This makes the exchange of data a piece of cake—you do not have to maintain different URLs of APIs, as you can leverage a common event schema and custom routing configuration based on, for example, event type. In Azure, such a service is called Azure Event Grid—a serverless event gateway, which is one of the newer cloud components available. With a pay-as-you-go pricing model, you can quickly build a reactive architecture that inverts communication between your services and makes them passive. In this chapter, you will learn how to work with Event Grid and integrate it with other Azure components.
