How to Deploy a Full-Stack Application to AWS
How to Deploy a Full-Stack Application to AWS
This guide provides a professional implementation path for deploying a full-stack application using EC2 for compute, RDS for data persistence, and S3 for static asset hosting.
What You'll Need
- AWS Account with administrative access
- A completed full-stack application (Frontend and Backend)
- SSH client (e.g., OpenSSH or PuTTY)
- Git version control system
Steps
Step 1: Provision an RDS Instance
Create a Relational Database Service (RDS) instance selecting the engine that matches your application's database. Configure the VPC security group to allow inbound traffic on the database port specifically from your future EC2 instance's IP or security group.
Step 2: Launch an EC2 Instance
Launch a t2.micro or t3.micro instance using an Amazon Linux 2 or Ubuntu AMI. Ensure you create and download a .pem key pair for secure SSH access and configure the security group to allow ports 80 (HTTP), 443 (HTTPS), and 22 (SSH).
Step 3: Configure the Server Environment
SSH into your instance and install the necessary runtime environments, such as Node.js, Python, or Java. Install a process manager like PM2 or systemd to ensure your backend application restarts automatically after a server reboot.
Step 4: Deploy the Backend Code
Clone your application repository from Git onto the EC2 instance. Install dependencies, set up your environment variables to point to the RDS endpoint, and run your database migrations to initialize the schema.
Step 5: Set Up a Reverse Proxy
Install Nginx to act as a reverse proxy, routing incoming web traffic from port 80 to your application's internal port. This improves security and allows you to handle SSL termination more efficiently.
Step 6: Host Frontend Assets on S3
Build your frontend production bundle and upload the static files to an S3 bucket. Enable 'Static Website Hosting' in the bucket properties and configure the public access settings to allow read access to the index.html and assets.
Step 7: Connect Domain and SSL
Point your domain's A record to the EC2 elastic IP or use Route 53 for DNS management. Use AWS Certificate Manager (ACM) or Let's Encrypt to implement HTTPS, ensuring all data transmitted between the client and server is encrypted.
Expert Tips
- Use an Elastic IP for your EC2 instance to prevent the public IP address from changing during restarts.
- Store sensitive credentials in AWS Secrets Manager rather than hardcoding them into environment files.
- Implement a CI/CD pipeline using GitHub Actions or AWS CodePipeline to automate future deployments.
