Phonebook Web Application on AWS with Terraform

The Phonebook Application aims to create a phonebook application in Python and deployed as a web application with Flask on AWS Application Load Balancer with Auto Scaling Group of Elastic Compute Cloud (EC2) Instances and Relational Database Service (RDS) using Terraform.

Overview

This project involves creating a phonebook web application using Python Flask and deploying it on AWS using Terraform. The application allows users to manage contacts in a phonebook, stored in a MySQL database on AWS RDS. The deployment includes an AWS Application Load Balancer, Auto Scaling Group of EC2 Instances, and a relational database service.

Features

  • Phonebook Operations: Users can search, add, update, and delete records in the phonebook.

  • Input Validation: The application validates user inputs, ensuring proper name and numeric phone number formats.

  • Web Application: The code transforms into a web application using Flask and three HTML templates.

  • AWS Deployment: Terraform deploys the application on AWS, utilizing Application Load Balancer, EC2 Instances, and RDS.

  • Security Measures: Security groups are configured to control traffic, and instances are launched in an Auto Scaling Group.
