Scalable and Secure Web Application

This repository contains the Terraform scripts that you need to create a scalable and secure web application architecture on AWS.

---

Requirements

• You must have Terraform installed on your computer.

• You must have an AWS account.

• A security group that allows inbound HTTP traffic.

• A key pair that can be used to connect to the EC2 instances.

• An EC2 instance running the web application.

• A load balancer that distributes traffic to the EC2 instances.

• A target group that defines the health checks for the EC2 instances.

• A listener that routes traffic from the load balancer to the target group.

• An RDS instance that stores the data for the web application.

Instructions: To create the web application architecture, you can follow these steps:

• Install Terraform.

• Clone this repository.

• Initialize Terraform.

• Plan the infrastructure changes.

• Apply the infrastructure changes.

• Securing the Communication Between the EC2 Instance and the RDS Instance

• The communication between the EC2 instance and the RDS instance is secured by using the following steps:

  1. The EC2 instance is configured to use the security group that allows inbound traffic only on port 3306.

  2. The RDS instance is configured to use the security group that allows outbound traffic only to the EC2 instance on port 3306.

  3. The RDS instance is configured with a password that is strong and unique.
