This document outlines the detailed design specifications for the "Terraform Infrastructure Builder" workflow. The goal is to generate production-ready, modular, and maintainable Terraform configurations for cloud infrastructure, encompassing core components like VPC, compute, storage, databases, and networking. This deliverable focuses on the architectural design of the generated Terraform code, conceptual user interaction, and best practices for usability and maintainability.
The core output of this builder will be a structured set of Terraform configurations. These specifications define the architecture and content of the generated code.

This "wireframe" represents the tangible output, which is the directory structure and file organization of the generated Terraform code, as described in section 1.2. The user receives a .zip archive or Git repository containing this structure.
While not for a visual UI, color palettes can be used conceptually to categorize infrastructure components or indicate status in reporting/visualization tools that might consume the generated infrastructure.
This palette helps visually distinguish different types of infrastructure when reviewing generated plans or diagrams.

#8BC34A (Light Green) - Represents active development, experimentation.#FFC107 (Orange) -This document outlines the detailed design specifications for the "Terraform Infrastructure Builder" user interface (UI) and user experience (UX). This design aims to provide an intuitive, powerful, and visually consistent platform for defining, generating, visualizing, deploying, and managing cloud infrastructure using Terraform.
The "Terraform Infrastructure Builder" is envisioned as a comprehensive platform that empowers users to easily construct, deploy, and manage their cloud infrastructure. This design phase focuses on creating a user interface that simplifies the complexity of Terraform while providing the necessary depth for advanced users.
