How Do I Integrate AWS EC2 With Amplify?

Introduction

Integrating AWS EC2 with Amplify allows developers to leverage the robust computing capabilities of EC2 while taking advantage of Amplify’s streamlined application development and deployment features. This integration is ideal for creating scalable web and mobile applications with a powerful backend infrastructure. In this guide, we will walk through the process of setting up an EC2 instance and an Amplify application to achieve this integration.

Step-by-Step Integration Process

1. Provider Configuration: Start by configuring AWS as your cloud provider. This is crucial for managing and deploying resources within the AWS ecosystem.

2. EC2 Instance: Create an EC2 instance to serve as your backend compute resource. This instance will handle the processing and backend operations for your application.

3. Security Group: Set up a security group to define firewall rules for your EC2 instance. This ensures that your instance is secure and can only be accessed through specified protocols and IP ranges.

4. Amplify App: Configure AWS Amplify to manage the lifecycle of your front-end application. Amplify simplifies the deployment process and offers features like automatic branch builds and environment management.

5. Outputs: Export relevant stack information, such as the instance ID, public DNS, and Amplify app details, to facilitate easy reference and management of your resources.

Program

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Security Group Definition
const allowSsh = new aws.ec2.SecurityGroup("allow_ssh", {
    namePrefix: "allow_ssh_",
    ingress: [{
        fromPort: 22,
        toPort: 22,
        protocol: "tcp",
        cidrBlocks: ["0.0.0.0/0"],
    }],
    egress: [{
        fromPort: 0,
        toPort: 0,
        protocol: "-1",
        cidrBlocks: ["0.0.0.0/0"],
    }],
});
// EC2 Instance Definition
const appServer = new aws.ec2.Instance("app_server", {
    ami: "ami-0c55b159cbfafe1f0",
    instanceType: aws.ec2.InstanceType.T2_Micro,
    securityGroups: [allowSsh.name],
    tags: {
        Name: "AppServerInstance",
    },
});
// Amplify App Definition
const myapp = new aws.amplify.App("myapp", {
    name: "myAmplifyApp",
    repository: "https://github.com/aws-amplify/amplify-js-samples",
    enableBranchAutoBuild: true,
    environmentVariables: {
        REACT_APP_API_URL: pulumi.interpolate`http://${appServer.publicDns}`,
    },
});
export const instanceId = appServer.id;
export const instancePublicDns = appServer.publicDns;
export const amplifyAppId = myapp.id;

Key Points

• Provider Configuration: Essential for utilizing AWS services.
• EC2 Instance: Acts as a scalable backend compute resource.
• Security Group: Protects your instance with defined access rules.
• Amplify App: Manages front-end application lifecycle and deployment.
• Outputs: Facilitates easy access to important resource identifiers.

Conclusion

In summary, by configuring an AWS provider, setting up a security group, deploying an EC2 instance, and establishing an Amplify app, you can create a powerful and scalable application infrastructure. This integration not only provides robust backend support but also streamlines the front-end development process, making it easier to manage and deploy applications efficiently. With the exported stack information, maintaining and scaling your application becomes a straightforward task.
