Deploy WordPress on AWS EC2 with ALB, Route 53 & SSL | Real-World AWS Architecture Guide

When most people deploy WordPress for the first time, they usually install everything on a single server.

That works for learning, but real-world production environments are designed differently.

In this guide, I’ll walk through a more practical AWS architecture using:

  • EC2 for the web server
  • RDS for the database
  • Application Load Balancer (ALB)
  • Route 53 for DNS
  • SSL using AWS Certificate Manager (ACM)

This setup introduces several important cloud and DevOps concepts while keeping the deployment beginner-friendly.

What We’re Building

By the end of this setup, you’ll have:

  • A WordPress application running on AWS
  • HTTPS enabled with SSL
  • Traffic routed through an Application Load Balancer
  • Database securely isolated in private subnets
  • Domain connected using Route 53

This architecture is much closer to real production deployments compared to a basic single-server setup.

Step 1: Create a Custom VPC

Instead of deploying everything into the default VPC, I created a custom VPC.

This helps you understand:

  • Networking
  • Isolation
  • High availability design

VPC Architecture

The setup includes:

  • 2 Public Subnets
  • 2 Private Subnets

spread across multiple availability zones.

Why Multiple Availability Zones Matter

Using multiple availability zones improves:

  • Availability
  • Fault tolerance
  • Reliability

If one zone has issues, resources in another zone can continue serving traffic.

Step 2: Launch EC2 Instance

Next, I launched an Amazon Linux EC2 instance inside a public subnet.

This EC2 instance acts as:

  • The web server
  • The WordPress host

Installing Apache, PHP & WordPress

After connecting to the server, I installed:

  • Apache
  • PHP
  • WordPress packages

Basic example:

sudo yum install httpd php php-mysqlnd -y

Then the Apache service was started and enabled.

Step 3: Configure Amazon RDS

Instead of storing the database directly on the EC2 server, I used Amazon RDS with MySQL.

This is a much better production practice because:

  • Database becomes managed
  • Backups become easier
  • Scaling is simpler

Private Subnet Placement

One important architectural decision:

👉 The RDS database was placed inside private subnets.

This prevents direct public internet access to the database.

Only the application server can communicate with it.

That’s an important security concept in AWS.

Step 4: Configure Security Groups

Security Groups act like firewalls in AWS.

Separate security groups were created for:

  • EC2
  • RDS
  • Application Load Balancer

Example Security Flow

ResourceAllowed Traffic
ALBHTTP/HTTPS from internet
EC2Traffic only from ALB
RDSTraffic only from EC2

This layered approach improves security significantly.

Step 5: Setup Application Load Balancer (ALB)

Instead of exposing EC2 directly to users, an Application Load Balancer was used.

The ALB:

  • Receives incoming traffic
  • Distributes requests
  • Acts as the public entry point

Why ALB is Important

ALBs are commonly used in production because they support:

  • HTTPS termination
  • Health checks
  • Path-based routing
  • Scalability

This makes them much more flexible than directly exposing servers.

Step 6: Enable HTTPS Using ACM

To secure the website, I requested a free SSL certificate using AWS Certificate Manager.

After validation:

  • The certificate was attached to the ALB
  • HTTPS became available

HTTP to HTTPS Redirect

To improve security, the ALB listener was configured to:

Redirect HTTP → HTTPS

This ensures all traffic uses encrypted communication.

Step 7: Configure Route 53

Next, the domain was connected using Amazon Route 53.

DNS records were pointed toward the Application Load Balancer.

Flow:

Domain → Route 53 → ALB → EC2 → RDS

Understanding this traffic flow is very useful when learning AWS networking.

Step 8: Configure WordPress Database Connection

Inside the WordPress configuration file:

wp-config.php

the RDS endpoint and database credentials were added.

This connects:

  • WordPress application
  • MySQL database

Why This Architecture Matters

This setup teaches several important cloud concepts together:

  • VPC networking
  • Public vs private subnets
  • Load balancing
  • Managed databases
  • SSL/TLS
  • DNS management
  • Security group design

Instead of learning services separately, you see how they work together in a practical deployment.

Common Beginner Mistakes

Some issues I noticed during setup:

  • Incorrect Security Group rules
  • RDS placed in public subnet accidentally
  • SSL certificate validation problems
  • Wrong Route 53 records
  • ALB health check failures

These are very common learning-stage mistakes.

Important AWS Cost Reminder

One thing beginners should always remember:

AWS resources continue running until deleted.

This includes:

  • EC2
  • RDS
  • ALB
  • Hosted Zones

Always clean up unused resources to avoid unnecessary charges.

Clean-Up Process

After testing:

  • Delete EC2 instance
  • Delete RDS database
  • Delete ALB
  • Remove Route 53 hosted zones if unused

This is especially important for learning environments.

Why This Setup is Valuable

This type of architecture is useful for understanding:

  • Real AWS deployments
  • Cloud networking
  • Security best practices
  • Scalable web hosting

Even if you later move to containers or Kubernetes, these fundamentals remain important.

Final Thoughts

Deploying WordPress on AWS is not just about hosting a website.

It’s a practical way to learn:

  • Networking
  • Security
  • Load balancing
  • SSL
  • Infrastructure design

Once you build it yourself, cloud architecture concepts become much easier to understand.

What You Should Do Next

Try building this setup yourself:

  • Create a custom VPC
  • Launch WordPress on EC2
  • Configure RDS
  • Add ALB + SSL
  • Connect Route 53

Hands-on learning makes a huge difference in cloud and DevOps.

👉 Bonus Tip

Once comfortable with this architecture, try:

  • Dockerizing WordPress
  • Auto Scaling Groups
  • CI/CD deployment pipelines
  • Infrastructure as Code using Terraform

That’s where production-grade DevOps workflows begin.
