General approach – build and package Java applications

This section provides a detailed guide on the essential steps required to build and package your Java applications, ensuring they are ready for deployment in a cloud environment.

1. Ensure your app is cloud-ready
   1. Stateless: Design your application to be stateless. This means that each request should be independent and not rely on previous requests. Store session data in a distributed cache like Redis instead of in memory.
   2. Configurable: Use external configuration files or environment variables to manage configuration. This can be done using Spring Boot’s application.properties or application.yaml files, or by using a configuration management tool. Here is an example:

server.port=8080
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password=password

2. Use a Build tool like Maven or Gradle
