## Overview

This repository is a hands-on cloud-infrastructure curriculum: users apply isolated Terraform labs to create and explore specific infrastructure patterns. The graph preserves the documented module capabilities and their outcomes; relationships are based on the README, since only the Lambda handler source was excerpted. The README also describes a capstone, but its files are absent from the supplied tree, so it is not mapped.

Main entry points: [`Module-10-Lab/main.tf`](https://github.com/adibuzz/it7027c-cloud-infra-tech-assignments/blob/main/Module-10-Lab/main.tf) (HAProxy balancing), [`Module-6-Lab/main.tf`](https://github.com/adibuzz/it7027c-cloud-infra-tech-assignments/blob/main/Module-6-Lab/main.tf) (Serverless function), [`Module-7-Lab/main.tf`](https://github.com/adibuzz/it7027c-cloud-infra-tech-assignments/blob/main/Module-7-Lab/main.tf) (Vault secrets), [`Module-3-Lab/main.tf`](https://github.com/adibuzz/it7027c-cloud-infra-tech-assignments/blob/main/Module-3-Lab/main.tf) (Messaging services)
