This repository contains the resources and scripts used to deploy a WordPress website on Amazon Web Services (AWS). The project leverages various AWS services to ensure high availability, scalability, and security for the WordPress application.
The WordPress website is hosted on EC2 instances within a highly available and secure architecture that includes:
- A Virtual Private Cloud (VPC) with public and private subnets across two Availability Zones (AZs) for fault tolerance and high availability.
- An Internet Gateway to allow communication between instances in the VPC and the internet.
- Security Groups acting as a virtual firewall to control inbound and outbound traffic.
- Public Subnets used for the NAT Gateway and Application Load Balancer, facilitating external access and load balancing.
- Private Subnets for web servers to enhance security.
- EC2 Instance Connect Endpoint for secure SSH access.
- An Application Load Balancer with a target group to distribute incoming web traffic across multiple EC2 instances.
- An Auto Scaling Group to automatically adjust the number of EC2 instances based on traffic, ensuring scalability and resilience.
- Amazon RDS for a managed relational database service.
- Amazon EFS for a scalable, elastic file storage system.
- AWS Certificate Manager for managing SSL/TLS certificates.
- AWS Simple Notification Service (SNS) for notifications related to the Auto Scaling Group activities.
- Amazon Route 53 for domain name registration and DNS management.
This script is used for the initial setup of the WordPress application on an EC2 instance. It includes steps for installing Apache, PHP, MySQL, and mounting the Amazon EFS to the instance.
