Enterprise Application: Simple Application Using AWS Elastic Beanstalk for C#, Java, and Golang

Below are examples of a simple application using AWS Elastic Beanstalk for C#, Java, and Golang. These examples assume a basic web application, and you would typically integrate your file upload and AWS S3 logic into the application.

C# AWS Elastic Beanstalk Example:

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello from AWS Elastic Beanstalk in C#!");

        // Include your file upload and S3 logic here

        Console.ReadLine(); // Keep the console application running for AWS Elastic Beanstalk
    }
}

Java AWS Elastic Beanstalk Example:

public class ElasticBeanstalkExample {
    public static void main(String[] args) {
        System.out.println("Hello from AWS Elastic Beanstalk in Java!");

        // Include your file upload and S3 logic here
    }
}

Golang (Go) AWS Elastic Beanstalk Example:

package main

import "fmt"

func main() {
    fmt.Println("Hello from AWS Elastic Beanstalk in Golang!")

    // Include your file upload and S3 logic here
}

These examples are simplified to demonstrate the structure of a basic application. In a real-world scenario, you would build a web application, handle HTTP requests, and integrate your file upload and S3 logic accordingly.

To deploy these applications on AWS Elastic Beanstalk, you would typically:

1. Create a web application based on your chosen programming language and framework (ASP.NET Core for C#, Spring Boot for Java, etc.).
2. Include the necessary AWS SDK for your language.
3. Integrate your file upload and S3 logic within your application.
4. Package your application and deploy it to AWS Elastic Beanstalk using the AWS Management Console or AWS CLI.

Ensure you configure your Elastic Beanstalk environment with the required settings, such as environment variables for your AWS credentials and S3 bucket information. Always follow security best practices and consider using IAM roles for your Elastic Beanstalk environment.
