How to Deploy a Full-Stack Application to AWS using EC2 and S3
How to Deploy a Full-Stack Application to AWS using EC2 and S3
This guide provides a professional deployment pipeline to host a static frontend on S3 and a dynamic backend on an EC2 instance, ensuring a scalable and secure production environment.
What You'll Need
- AWS Account
- Full-stack application source code (Git repository)
- AWS CLI configured locally
- Domain name (optional, via Route 53)
Steps
Step 1: Configure VPC and Networking
Establish a Virtual Private Cloud (VPC) with a public subnet to house your EC2 instance. Configure a Security Group to allow inbound traffic on port 80 (HTTP), 443 (HTTPS), and 22 (SSH) for administrative access.
Step 2: Provision the EC2 Backend
Launch an EC2 instance using an Amazon Machine Image (AMI) such as Ubuntu. Attach an Elastic IP to ensure your backend endpoint remains constant across instance reboots.
Step 3: Set Up Backend Environment
SSH into the instance and install necessary runtimes, such as Node.js or Python. Use a process manager like PM2 or Gunicorn to keep the application running in the background and configure Nginx as a reverse proxy to route traffic to your app port.
Step 4: Deploy Static Assets to S3
Create an S3 bucket and enable 'Static Website Hosting' in the properties tab. Upload your compiled frontend build files (HTML, CSS, JS) and set the bucket policy to allow public read access for the objects.
Step 5: Connect Frontend to Backend
Update your frontend environment variables to point to the EC2 Elastic IP or custom domain. Re-deploy the build to S3 to ensure the client-side application can successfully make API calls to the backend.
Step 6: Implement CI/CD Integration
Set up a GitHub Action or AWS CodePipeline to automate deployments. Configure the pipeline to trigger a build on push, sync files to S3 via AWS CLI, and update the EC2 instance using a deployment script or SSH command.
Step 7: Configure DNS and SSL
Map your domain to the S3 bucket and EC2 instance using Route 53. Use AWS Certificate Manager (ACM) to provision SSL certificates, typically routed through an Application Load Balancer for secure HTTPS traffic.
Expert Tips
- Use IAM roles instead of hardcoded AWS access keys on your EC2 instance for better security.
- Implement a CloudFront distribution in front of S3 to enable global caching and faster load times.
- Regularly snapshot your EBS volumes to ensure quick recovery in case of system failure.
