The Complete Guide to Hosting Web Applications on AWS Cloud


Understanding AWS Amplify

AWS Amplify is a cloud-based service that enables developers to build, deploy, and host full stack web and mobile applications. It simplifies backend configuration, authentication and deployment, making it an ideal choice for hosting modern applications.

Pros of Using AWS Amplify

  • Easy Deployment: Automates the build and deployment process from Git repositories.
  • Scalability: Supports applications of any scale with managed hosting.
  • Custom Domains and HTTPS: Allows custom domains with built-in HTTPS support.
  • CI/CD Integration: Provides continuous deployment from connected Git repositories.

 

How to Deploy a Web Application on AWS Amplify

Follow Below Steps to Deploy Your web Application on AWS

Step 1: Set Up an AWS Account

Go to AWS Console and log in. If you don’t have an account, sign up for one.

 

Step 2: Create a New Amplify App

Open the AWS Amplify Console. Click Get Started under the Host your web app section. Choose Git based deployments and connect your repository (GitHub, GitLab, Bitbucket or AWS CodeCommit).

Step 3: Configure Build Settings

Amplify automatically detects the framework (React, Angular, Vue etc.). You can modify the build settings by updating the amplify.yml file if needed. Click Save and Deploy to start the deployment process.

Command to initialize Amplify project:

amplify init

Command to add hosting:

amplify add hosting

Command to publish changes:

amplify publish

 

Step 4: Verify Deployment

Once the deployment is complete, Amplify provides a default domain like https://yourapp.amplifyapp.com Open the URL to confirm that your web application is live.

Step 5: Configure Custom Domain (Optional)

Go to the Domain Management section in the Amplify Console. Add your custom domain (e.g., www.mywebapp.com). Update your DNS records in your domain registrar to point to the provided Amplify endpoints.

Command to set a custom domain:

amplify domain add www.mywebapp.com

 

Step 6: Set Up Access Control

By default, your website is public. Navigate to the Access Control section if you need to restrict access to specific users.

Step 7: Monitor and Manage Your Application

Use the Amplify Console to monitor deployment history, check logs, and manage application settings. Enable automatic deployments to push updates whenever you make changes in the repository.

Command to check Amplify status:

amplify status

Command to remove hosting if needed:

amplify remove hosting

Further Remarks

AWS Amplify is best suited for hosting modern applications that require fast deployments and easy integration with backend services. However, it primarily supports static web apps and dynamic functionality should be handled through AWS Lambda, API Gateway or other backend services.

Amplify automatically provisions HTTPS for secure communication, ensuring your web application is secure by default.

Hosting in AWS Amplify is cost effective, as you only pay for the resources you use, making it a scalable and efficient solution for developers.
