# Scalable Phonebook Application

A highly available phonebook web application deployed on AWS with auto-scaling capabilities, built using Python Flask, MySQL RDS, and Infrastructure as Code with Terraform.

## Overview

This project demonstrates enterprise-level cloud architecture by implementing a scalable phonebook application. It showcases:

- High Availability using AWS Application Load Balancer

- Auto-scaling EC2 instances

- Managed MySQL database with AWS RDS

- Infrastructure as Code using Terraform

- CI/CD best practices

## Features

- **Search**: Find contacts quickly with case-insensitive search

- **Add/Update**: Create and modify contact information

- **Delete**: Remove outdated contacts

- **Data Validation**: Smart input validation for names and phone numbers

- **Auto-scaling**: Handles traffic spikes automatically

- **High Availability**: Runs across multiple availability zones

## Architecture

- Application Load Balancer with auto-scaling EC2 instances

- MySQL RDS for persistent storage

- Multiple security groups for enhanced security

- Distributed across availability zones

## Technologies

- **Backend**: Python Flask

- **Database**: AWS RDS (MySQL 8.0)

- **Infrastructure**: 

  - AWS (ALB, EC2, Auto Scaling, RDS)

  - Terraform for IaC

- **Security**: Custom security groups, isolated database tier

## Quick Start

1. **Prerequisites**

   - AWS Account

   - Terraform installed

   - AWS CLI configured

2. **Deployment**

   ```bash

   # Clone repository

   git clone [repository-url]

   # Initialize Terraform

   terraform init

   # Deploy infrastructure

   terraform apply

   # Access application (URL in Terraform output)

   ```

## Infrastructure Details

- Load balanced across availability zones

- Auto-scales between 1-3 instances

- t2.micro EC2 instances with custom launch template

- Private subnet RDS instance

- Automated deployment with Terraform
