1. Executive Summary

The "Terraform Infrastructure Builder" workflow aims to automate the provisioning of cloud infrastructure components, including Virtual Private Cloud (VPC), compute resources, storage, databases, and networking, using Terraform. This initial phase focuses on gathering and defining the core requirements and design principles that will guide the subsequent infrastructure-as-code development. The goal is to produce highly detailed specifications that translate business and technical needs into actionable infrastructure designs, ensuring the deployed environment is optimized for performance, cost, security, and operational efficiency.

2. Core Infrastructure Requirements Gathering

To build a truly production-ready environment, a clear understanding of the underlying requirements is paramount. This section details the key areas for requirements gathering.
