Azure Spring Apps is the new name for the Azure Spring Cloud service. Although the service has a new name, you'll see the old name in some places for a while as we work to update assets such as screenshots, videos, and diagrams.
This article applies to: ✔️ Standard consumption and dedicated (Preview) ✔️ Basic/Standard ✔️ Enterprise
This article explains how to deploy a Spring Boot event-driven application to Azure Spring Apps.
The sample project is an event-driven application that subscribes to a Service Bus queue named lower-case, and then handles the message and sends another message to another queue named upper-case. To make the app simple, message processing just converts the message to uppercase. The following diagram depicts this process:
This article provides the following options for deploying to Azure Spring Apps:
The Azure portal option is the easiest and the fastest way to create resources and deploy applications with a single click. This option is suitable for Spring developers who want to quickly deploy applications to Azure cloud services.
The Azure portal + Maven plugin option is a more conventional way to create resources and deploy applications step by step. This option is suitable for Spring developers using Azure cloud services for the first time.
The Azure Developer CLI option is a more efficient way to automatically create resources and deploy applications through simple commands. The Azure Developer CLI uses a template to provision the Azure resources needed and to deploy the application code. This option is suitable for Spring developers who are familiar with Azure cloud services.
