Traffic-distributing-website-deployment

This Terraform project sets up a highly available web application on AWS. The infrastructure includes a VPC, subnets, an internet gateway, route tables, security groups, EC2 instances, an Application Load Balancer (ALB), and an S3 bucket.

Architecture Overview

Components

• 🌐 VPC: A Virtual Private Cloud with two subnets in different availability zones.
• 🌍 Internet Gateway: Enables internet connectivity for the VPC.
• 🛣️ Route Tables: Direct traffic to the internet gateway.
• 🔒 Security Group: Controls inbound and outbound traffic for the EC2 instances and ALB.
• 🖥️ EC2 Instances: Two instances initialized with user data scripts, placed in different subnets.
• ⚖️ Application Load Balancer (ALB): Distributes incoming traffic across the EC2 instances.
• 📦 S3 Bucket: Storage for various application data.

Prerequisites

• Terraform installed on your local machine.
• AWS CLI configured with appropriate permissions.
• AWS credentials configured.
