is a big data streaming platform and event ingestion service. It can receive and process millions of events per second. Data sent to an event hub can be transformed and stored by using any real-time analytics provider or batching/storage adapters.
Spring Cloud Azure provides various modules for sending messages to and receiving messages from Event Hubs using Spring frameworks.
You can use the following modules independently or combine them for different use cases:
Spring Cloud Azure Event Hubs Starter

In this tutorial, the configurations and code don't have any authentication operations. However, connecting to an Azure service requires authentication. To complete the authentication, you need to use the Azure Identity client library. Spring Cloud Azure uses DefaultAzureCredential, which the Azure Identity library provides to help you get credentials without any code changes.
DefaultAzureCredential supports multiple authentication methods and determines which method to use at runtime. This approach enables your app to use different authentication methods in different environments - such as local or production environments - without implementing environment-specific code. For more information, see the
To use Azure CLI, IntelliJ, or other methods to complete the authentication in local development environments, see
