Spring Boot Web Application Deployment on AWS Elastic Beanstalk with AWS RDS

This post briefly documents the process of deploying a Spring Boot based web application on the AWS Elastic Beanstalk platform. This application will be connected to an AWS managed MySQL Relational Database system.

Introduction

AWS Elastic Beanstalk is an orchestration service offered by Amazon Web Services for deploying applications which orchestrates various AWS services, including EC2, S3, Simple Notification Service, CloudWatch, autoscaling, and Elastic Load Balancers.

Amazon Relational Database Service (RDS) is a distributed relational database service by Amazon Web Services. It is a web service running "in the cloud" designed to simplify the setup, operation, and scaling of a relational database for use in applications.

Minimum Requirements

• Access to AWS Management Console

Sample Project

Spring Boot Minimal Web App is the sample Spring Boot web application i've used to deploy on the AWS Elastic Beanstalk platform.

Application URL

Navigate to http://localhost:8080/ to discover the application URLs.

Building the Executable Jar

Find details on how to build an executable jar here.

Configuration

1. In the application.properties file present in the resources folder, set the spring.profiles.active value to mysql-aws.

2. In the application-mysql-aws.properties file, set the server.port value to 5000. Also, set the aws.rds.database.endpoint value in the same file to the database endpoint generated after following the steps in the next section.

Step 2 - AWS Beanstalk - Creating Environment

Step 2.1 - Create a new environment

Navigate to the AWS Elastic Beanstalk console, click on "Create a new environment"

Step 2.2 - Select environment tier

Choose the appropriate environment tier based on your application's requirements.

Step 2.3 - Create a web server environment

Provide the necessary details to create a web server environment.

Step 2.4 - Environment information

Enter the required information about your environment, including the environment name, domain, and description.

Step 2.5 - Platform

Select the platform for your application. For a Spring Boot application, you can choose a Java platform.

Step 2.6 - Application code

Upload your Spring Boot application's executable jar file or a ZIP file containing your application code.

Step 2.7 - Log

After deploying your application, review the logs to ensure everything is running smoothly.

Step 3 - Edit inbound rules for the web app deployed on Elastic Beanstalk to access the Database

Edit inbound rules

Edit the inbound rules for the security group associated with your Elastic Beanstalk environment to allow access to the database.

Environment Overview

Step 4 - Environment setup complete

Once the environment setup is complete, navigate to the Elastic Beanstalk dashboard to view the details.

Step 4.1 - Application

Check the deployed application details to ensure it is running as expected.

Step 4.2 - Configuration

Review and adjust the configuration settings for your environment.

Step 4.3 - Monitoring

Monitor the health and performance of the application.

Step 4.4 - Events

Review the event logs to track any issues or updates related to your environment.

Step 5 - Output

Step 5.1 - Web Page

Verify that your web application is accessible by navigating to the provided URL.

Step 5.2 - API Endpoint

Test the API endpoints to ensure they are functioning correctly.

Step 5.3 - API In Action

Demonstrate the API in action by making sample requests and verifying the responses.

Step 6 - Cleanup

Step 6.1 - Terminate Environment

To avoid incurring charges for resources you are no longer using, terminate the Elastic Beanstalk environment.

Step 6.2 - Confirm Environment Termination

Confirm the environment termination to ensure all resources are properly cleaned up.

Conclusion

Deploying a Spring Boot application on AWS Elastic Beanstalk and connecting it to an AWS RDS MySQL database streamlines the process of managing infrastructure and scaling applications. AWS provides a robust set of tools to monitor, manage, and maintain your application, ensuring high availability and reliability. Following this guide, you can leverage these services to deploy and manage your Spring Boot applications.
