AWS Core Services

AWS offers a wide range of core services that are essential for building and deploying applications on the cloud. Let's explore some of the fundamental AWS services:

1. Amazon Elastic Compute Cloud (EC2)

Amazon EC2 provides resizable compute capacity in the cloud. It allows you to quickly provision virtual servers, known as instances, and scale them as per your requirements. EC2 instances are highly configurable and can be customized based on your specific application needs. If you're familiar with Java and Spring Boot, you can leverage EC2 to deploy your Java applications on the cloud.

Here's a simple Java program that prints "Hello, AWS!":

In this example, the main method prints out the message "Hello, AWS!". You can replace this logic with your own Java code to perform more complex operations.

2. Amazon Simple Storage Service (S3)

Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. It allows you to store and retrieve large amounts of data, such as images, videos, and documents, from anywhere on the web. You can think of S3 as a highly reliable and cost-effective storage solution for your applications.

3. Amazon Relational Database Service (RDS)

Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. It supports multiple database engines, such as MySQL, PostgreSQL, Oracle, and SQL Server, and provides automated backups, software patching, and monitoring capabilities. RDS is a great choice if you need a managed database service for your application.

By exploring these core services, you'll gain a solid foundation in AWS and be able to leverage them to build and deploy applications on the cloud.

        // Replace with your Java logic here

        System.out.println("Hello, AWS!");
