This repository contains Terraform scripts to set up a highly available and scalable WordPress application on AWS. The architecture leverages various AWS services, including VPC, EC2, RDS, ALB, and Auto Scaling Group, to ensure fault tolerance, security, and performance.

• AWS Region: US East 1
• VPC: 10.0.0.0/16
• Public Subnets:
  • 10.0.100.0/24 (AZ: US East 1a)
  • 10.0.101.0/24 (AZ: US East 1b)
• Private Subnets:
  • 10.0.4.0/24 (AZ: US East 1a)
  • 10.0.8.0/24 (AZ: US East 1b)
• Internet Gateway: Provides internet access to public subnets.
• Application Load Balancer (ALB): Distributes incoming traffic across multiple WordPress instances.
• Auto Scaling Group (ASG): Ensures high availability and scalability of WordPress instances.
• WordPress Instances: Deployed in public subnets, managed by ASG.
• RDS (MySQL): Deployed in private subnets for secure database management.
• Security Groups:
  • Web Security Group: Applied to WordPress instances.
  • Database Security Group: Applied to RDS instance.
• Route Tables:
  • Public Route Tables: Associated with public subnets.
  • Private Route Tables: Associated with private subnets.

• AWS Account
• Terraform installed on your local machine
• AWS CLI configured with necessary permissions

git clone https://github.com/ssram4298/terraform-wordpress.git
cd terraform-wordpress

Ensure your AWS CLI is configured with the necessary credentials:

aws configure

Edit the variables.tf file to customize the configuration according to your requirements:

variable "region" {
  description = "AWS Region"
  default     = "us-east-1"
}

variable "vpc_cidr" {
  description = "VPC CIDR"
  default     = "10.0.0.0/16"
}

variable "public_subnets" {
  description = "Public Subnets CIDRs"
  default     = ["10.0.100.0/24", "10.0.101.0/24"]
}

variable "private_subnets" {
  description = "Private Subnets CIDRs"
  default     = ["10.0.4.0/24", "10.0.8.0/24"]
}

# Add other variables as necessary

Initialize the Terraform working directory:

terraform init

Review the execution plan and apply the configuration:

terraform plan
terraform apply

After the Terraform script completes, you can access your WordPress application using the DNS name provided by the ALB.

To destroy the resources created by Terraform, run:

terraform destroy
