EC2 + Load Balancer + Auto Scaling

Explanation

Package the Spring Boot application as an executable JAR file before deploying it to Elastic Beanstalk.

Code:

mvn clean package

Generated file:
target/app.jar

Explanation

Elastic Beanstalk environments can be configured with Java platform versions, environment variables, instance types, and scaling settings.

Code:

Environment Variables:
SERVER_PORT=5000
DB_USERNAME=${DB_USERNAME}
DB_PASSWORD=${DB_PASSWORD}
SPRING_PROFILES_ACTIVE=prod

Explanation

Deploy the application using the Elastic Beanstalk command-line interface.

Code:

eb init
 eb create springboot-prod-env
 eb deploy

Explanation

Elastic Beanstalk monitors the application and can automatically replace unhealthy instances or scale the application based on demand.
