Question

• I understand that Azure Spring Apps does not recommend deploying in WAR format, but is this correct?
  • Quickstart page for Azure Spring Apps (https://learn.microsoft.com/en-us/azure/spring-apps/quickstart?pivots=sc-enterprise&tabs=Azure-portal%2CAzure-portal-ent%2CConsumption-workload) I understand that it only describes how to generate and deploy jars generated using Spring Boot.
  • Also, from a feasibility point of view, please let me know if it is possible to deploy it in War format and make it work.

@kazuya kurosawa Thanks for reaching out. Azure Spring Apps is primarily designed to host Spring Boot applications, which are typically packaged as JAR files. If you have a Java web application packaged as a WAR file, Azure App Service is a more suitable choice. Azure App Service supports deploying Java web applications in the form of WAR files and provides a fully managed platform for building, deploying, and scaling web apps and APIs. https://techcommunity.microsoft.com/t5/apps-on-azure-blog/deploy-spring-boot-application-to-app-service-tomcat-stack-using/ba-p/3708959

The reason for this is that Spring Boot and Spring MVC have different deployment strategies. Spring Boot is designed to be deployed as a standalone application with an embedded server, which is why it’s typically packaged as a JAR file. On the other hand, Spring MVC is a traditional Java web framework that’s designed to run within a web container, which is why it’s typically packaged as a WAR file. Therefore, it’s recommended to use Azure App Service for deploying WAR files. I hope this helps! Let me know incase of further queries.
