⚡ Duolingo-Style Interactive Mastery for Enterprise Terraform & Google Cloud

Master Terraform Foundations, Fabric FAST & Your Own Cloud Repositories.

CloudGraft transforms static Infrastructure-as-Code documentation and complex Git repositories into interactive stepping-stone learning paths, AST code-pinpoint labs, role-based leaderboards, and FSRS v4 spaced-repetition mastery.

Finite 9-Level Curriculum

Terraform Foundations

Progress from core HCL blocks, provider version constraints, and `.tfvars` override precedence through `for_each` comprehensions, `dynamic` blocks, `try()`/`coalesce()`, and zero-downtime `moved {}` state refactoring.

Curated Cloud Blueprints

Google Cloud Fabric FAST

Train by Cloud Role Category (`Security & Identity`, `Networking`, `Compute & Serverless`, `Databases & Storage`) or drill into individual upstream modules (`kms`, `net-vpc`, `cloud-run-v2`, `cloudsql-instance`).

Live Codebase Ingestion

Custom Organization Repos

Connect your internal Terraform repositories (`main.tf`, `variables.tf`, `prod.tfvars`, `tfplan.json`). CloudGraft parses the HCL Abstract Syntax Tree (AST) and auto-generates 2 to 9 custom levels tailored to your infrastructure.

01 • AST CODE PINPOINT
Click Real HCL Tokens

Identify exact lines and expressions across `main.tf`, `variables.tf`, and `prod.tfvars` before answering.

02 • IMMEDIATE REMEDIATION
Socratic Hints & Re-Queue

Missed concepts are remediated on the spot with Socratic AI guidance before completing the node.

03 • FSRS v4 SPACED REPETITION
Long-Term Memory Retention

Calculates Stability (S) and Difficulty (D) per engineer to schedule reviews right before knowledge decay.

04 • DUAL LEADERBOARDS
Org & Role Rankings

Earn XP, maintain daily streaks, and benchmark mastery across your entire organization or engineering role.

Unified Visual Learning Platform

Built Around Three Visual Learning Paths

CloudGraft turns static Terraform codebases into interactive, bite-sized stepping stones. Choose a structured path, inspect real HCL in the browser IDE, and level up your cloud architecture skills.

Terraform Foundations

A 9-level zero-to-hero journey covering providers, `.tfvars` precedence, `for_each` loops, built-in functions, and zero-downtime `moved {}` state refactoring.

9 Levels • 45 Stars Core HCL Mastery
VPC KMS RUN SQL

Google Cloud Fabric FAST

Train on Google Cloud’s production `FAST` architectures by role category (`Networking`, `Security`, `Serverless`) or pick any single module (`net-vpc`, `kms`, `cloud-run-v2`).

Learner & Platform Guide

How CloudGraft Interactive Code Challenges Work

Every challenge pairs a live multi-file Terraform IDE (main.tf, module.tf, variables.tf, prod.tfvars, and tfplan.json) directly with the exact code under inspection.

📖 Describe What Is Happening

Analyze highlighted blocks inside main.tf and module.tf to explain how modules, loops, and lifecycle rules behave.

🏗️ Identify Provisioned Resources

Multi-select the exact cloud resources (google_compute_network, google_kms_crypto_key) created across root and child module files.

🎯 Interactive Code Walk

Step through the IDE and click the exact line or HCL token (prevent_destroy, cidrsubnet) that implements an architectural requirement.

Enterprise Organization & RBAC Administration Google Cloud Identity Platform Multi-Tenancy + KMS Envelope Encryption

Organization Setup (`ORG_ADMIN` / `ADMIN`), Domain Approvals, Teams & Fine-Grained Database RBAC

The initial customer administrator (ORG_ADMIN) configures the Organization Name, GCP Organization ID, Primary Email Domain, and Engineering Teams. Self-registered domain users enter the approval queue, receive an encrypted temporary password upon admin approval, and complete a mandatory password change on first login.
