Spring Boot Backend Development Course, Creating RDS in Elastic Beanstalk

1. Introduction

We utilize various tools and frameworks for fast and efficient backend development in today’s web development environment. In particular, Spring Boot is an excellent framework for quickly developing Java-based applications. In this course, we will use Spring Boot for backend development and look at how to create a Relational Database Service (RDS) in AWS’s Elastic Beanstalk.

2. What is Spring Boot?

Spring Boot is an open-source framework built on top of the Spring Framework, helping to develop applications quickly with minimal configuration. Key features include auto-configuration, standalone application development, metrics, and monitoring capabilities.

Using Spring Boot allows for simple annotations to handle necessary configurations without complicated XML file setups, enabling rapid prototyping. Moreover, it allows the easy addition of required libraries by leveraging various Starter dependencies.

3. AWS and Elastic Beanstalk

AWS (Amazon Web Services) is a cloud computing platform that provides reliable and scalable computing capacity. Among its services, Elastic Beanstalk is a Platform as a Service (PaaS) that supports easy deployment and scaling of web applications.

Elastic Beanstalk automatically scales servers and provides load balancing to maintain high availability. Therefore, developers can focus more on application development rather than infrastructure management.

4. What is RDS?

AWS’s Relational Database Service (RDS) automates complex tasks required for users to set up and manage databases. Supported database engines include MySQL, PostgreSQL, Oracle, SQL Server, and others.

With RDS, the processes of database backups, lifecycle management, security, software patching, and database monitoring can be handled automatically. This functionality allows developers to focus on application development more efficiently.

5. Preparing the Development Environment

  1. Creating an AWS account: An AWS account is necessary to use AWS services. Create an account and log in.
  2. Setting up the Java development environment: Java 11 or higher must be installed, and IDEs such as IntelliJ IDEA or Eclipse can be used.
  3. Initial Spring Boot setup: Use Spring Initializr to generate a Spring Boot starter project.
  4. Add the ‘Spring Web’, ‘Spring Data JPA’, and ‘MySQL Driver’ dependencies.

6. Configuring the Spring Boot Application

Set the RDS database connection information in the application.properties or application.yml file of the created Spring Boot project.

                
                spring.datasource.url=jdbc:mysql://:3306/
                spring.datasource.username=
                spring.datasource.password=
                spring.jpa.hibernate.ddl-auto=update
                spring.jpa.show-sql=true

Afterward, create Entity and Repository classes to implement interactions with the database. For example, set up operations for CRUD (Create, Read, Update, Delete) on user information.

7. Configuring the Elastic Beanstalk Environment

  1. Log in to the AWS Management Console and select Elastic Beanstalk services.
  2. Click the ‘Create New Application’ button to create an application.
  3. Enter the application name and description, then select the platform. Choose Spring Boot.
  4. Click ‘Configure more options’ to add RDS database configurations.
  5. Input the information for the DB instance name, database name, username, and password.
  6. Once all settings are complete, click ‘Create environment’ to create the environment.

8. Deploying the Application

After configuring the environment, package the Spring Boot application into a .jar file. Upload this file to the Elastic Beanstalk environment for deployment. In the AWS Management Console, click ‘Upload and Deploy’ and select the .jar file.

Once deployment is complete, you can access the application via the provided URL.

9. Conclusion

In this course, we learned how to set up an environment for backend development using Spring Boot and how to configure RDS in AWS’s Elastic Beanstalk for implementing communication with the database. This series of processes will contribute to more efficient web application development by utilizing various services and data in a cloud environment.

This method of combining Spring Boot and AWS is practically used by many companies and will help enhance your development skills. The next course will cover more advanced topics, so look forward to it.
