How to Deploy a Full-Stack Web Application to AWS and Vercel
How to Deploy a Full-Stack Web Application to AWS and Vercel
This guide outlines a hybrid deployment strategy using Vercel for the frontend and AWS for the backend to ensure optimal performance, scalability, and developer experience.
What You'll Need
- GitHub account with project repository
- Vercel account
- AWS account (IAM user with administrative access)
- Node.js and npm installed locally
Steps
Step 1: Prepare the Backend on AWS
Containerize your backend application using Docker and push the image to Amazon Elastic Container Registry (ECR). Deploy the container using Amazon ECS (Elastic Container Service) or App Runner for a managed experience. Ensure the service is exposed via an Application Load Balancer to provide a stable public endpoint.
Step 2: Configure AWS Security Groups
Modify your EC2 or ECS security group settings to allow inbound traffic on the specific port your application uses (typically port 80 or 443). Restrict access to known IP ranges if necessary, but ensure the Vercel deployment environment can reach the API endpoint.
Step 3: Connect Frontend to Vercel
Import your GitHub repository into the Vercel dashboard. Vercel will automatically detect your framework (e.g., Next.js, React) and configure the build settings. Trigger an initial deployment to verify that the static assets build correctly.
Step 4: Manage Environment Variables
Add your AWS API endpoint URL and any secret keys to the Vercel project settings under 'Environment Variables'. This prevents sensitive credentials from being hardcoded into your version control and allows the frontend to communicate with the AWS backend.
Step 5: Establish CI/CD Pipelines
Configure GitHub Actions or Vercel's native integration to automate deployments. Set up a pipeline where pushes to the 'main' branch trigger a production build on Vercel and a rolling update to the AWS ECS service via a deployment script or AWS CodePipeline.
Step 6: Configure Custom Domains and DNS
Add your primary domain to Vercel and update your DNS records (A and CNAME) via your domain registrar. For the backend, use AWS Route 53 to create a subdomain (e.g., api.yourdomain.com) that points to your AWS Load Balancer.
Step 7: Implement SSL and HTTPS
Enable managed SSL certificates through Vercel for the frontend. For the AWS backend, use AWS Certificate Manager (ACM) to attach an SSL certificate to your Load Balancer, ensuring all data transmitted between the client and server is encrypted.
Expert Tips
- Use a .env.example file in your repository to document required variables without exposing actual secrets.
- Implement a health check endpoint in your AWS backend to allow the load balancer to automatically replace unhealthy instances.
- Leverage Vercel's Preview Deployments to test backend changes in a staging environment before merging to production.
