How to Deploy a Full-Stack Application to AWS Using EC2 and RDS
How to Deploy a Full-Stack Application to AWS Using EC2 and RDS
This guide provides a production-ready blueprint for deploying a full-stack application by isolating the database layer and automating the deployment pipeline.
What You'll Need
- AWS Account
- Application code hosted on GitHub or GitLab
- SSH key pair (.pem file)
- Basic familiarity with the Linux command line
Steps
Step 1: Configure VPC and Networking
Create a Virtual Private Cloud (VPC) with public subnets for your EC2 instance and private subnets for your RDS instance. This ensures your database is not directly accessible from the open internet, significantly improving security.
Step 2: Provision the RDS Database
Launch an Amazon RDS instance within your private subnet, selecting the engine that matches your application's needs (e.g., PostgreSQL or MySQL). Configure the database security group to allow inbound traffic on the database port only from the EC2 security group.
Step 3: Launch the EC2 Instance
Deploy an EC2 instance using an Amazon Linux or Ubuntu AMI. Assign a security group that permits inbound traffic on port 80 (HTTP), 443 (HTTPS), and port 22 (SSH) from your specific IP address.
Step 4: Environment Setup and Runtime Installation
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 application restarts automatically after a crash or server reboot.
Step 5: Configure Application Environment Variables
Create a .env file on the server to store sensitive credentials, including the RDS endpoint, database name, and API keys. Avoid committing this file to version control to prevent security leaks.
Step 6: Set Up a Reverse Proxy with Nginx
Install Nginx to act as a reverse proxy, forwarding incoming web traffic from port 80 to the internal port where your application is running. This allows for better load handling and simplifies the implementation of SSL certificates.
Step 7: Implement CI/CD Pipeline
Configure GitHub Actions or AWS CodePipeline to automate the deployment process. Set up a workflow that triggers on pushes to the main branch, pulls the latest code to EC2, installs dependencies, and restarts the application service.
Expert Tips
- Use an Elastic IP for your EC2 instance to prevent the public IP address from changing upon reboot.
- Enable 'Multi-AZ Deployment' for RDS to ensure high availability and automatic failover in production.
- Implement an SSL certificate via AWS Certificate Manager or Let's Encrypt to secure data in transit.
