## Overview
This repository is a Terraform training workspace organized as a progression from simple single-stack infrastructure to modular, multi-environment platform provisioning.
1. **Repository intent**
The top-level README frames the repo as a learning roadmap for AWS + Terraform, moving through **basic**, **intermediate**, and **advanced** infrastructure patterns. The main architectural theme is increasing separation of concerns: from one Terraform root, to reusable modules, to environment orchestration with Terragrunt and CI.
2. **Basic phase: single-root Terraform stack**
`terraform-all-projects/terraform-projects/project-01-static-website` is the simplest boundary: one Terraform configuration with `main.tf`, `variables.tf`, `outputs.tf`, and `terraform.tfvars`. This looks like a self-contained deployment for a static website, with no module layering.
3. **Intermediate phase: reusable module-based infrastructure**
`project-02-web-app-infra` introduces a more realistic Terraform architecture:
- `bootstrap/` for initial setup
- `environments/dev/` as the environment-specific root
- `modules/` for reusable components
This project demonstrates the common pattern of separating environment wiring from infrastructure implementation.
4. **Intermediate module boundaries**
The intermediate modules are split by responsibility:
- `vpc` for network foundation
- `security` for security groups or access controls
- `ec2` for compute
- `alb` for traffic distribution
- `rds` for managed database
The likely data flow is foundational network outputs feeding security and compute, then compute being attached behind the load balancer, with database connectivity handled through private networking and security rules.
5. **Intermediate environment isolation**
The `environments/dev` root is where module instances are composed together. This suggests a pattern where environment-specific values are passed in through `terraform.tfvars` and variables, while module internals stay reusable across future environments.
6. **Advanced phase: Terragrunt-based platform composition**
`project-03-enterprise-platform` moves from plain Terraform roots to **Terragrunt orchestration**. The architecture is split into:
- shared root configuration at `terragrunt.hcl`
- environment-level config under `environments/dev` and `environments/prod`
- one Terragrunt unit per component (`vpc`, `alb`, `ecs`, etc.)
This creates a clear boundary between module code and deployment composition.
7. **Advanced environment structure**
The `environments/dev` and `environments/prod` trees show a multi-environment deployment model. Each environment has its own `env.hcl`, and each service/component has its own `terragrunt.hcl`, which implies independently managed stacks with shared conventions and environment-specific inputs.
8. **Advanced platform modules**
The advanced modules reflect a full application platform:
- `vpc` for networking
- `alb` for ingress/load balancing
- `ecs` for container compute
- `aurora` for managed relational database
- `elasticache` for caching
- `kms` for encryption key management
- `waf` for edge/application protection
- `monitoring` for observability
This is a layered platform architecture where shared infrastructure is provisioned once and application-facing services depend on it.
9. **Security and governance boundaries**
Security is treated as a first-class subsystem in the advanced project through `kms` and `waf`, and implicitly through network segmentation in `vpc`. This suggests the repo models not just functional provisioning, but also encryption, perimeter protection, and environment separation.
10. **Automation and quality gates**
The advanced project includes `.github/workflows/terraform-ci.yml` and `drift-detection.yml`, indicating automated validation and ongoing state drift monitoring. That means the operational boundary extends beyond Terraform code into CI/CD and infrastructure governance.
11. **Testing layer**
`tests/kms_test.tftest.hcl` and `tests/vpc_test.tftest.hcl` show Terraform-native tests for module behavior. These tests sit between module implementation and environment composition, validating core assumptions about key infrastructure primitives.
12. **Architecture diagram takeaway**
If you diagram this repo, model it as three maturity stages:
- a **single-stack deployment**
- a **module-composed environment**
- a **Terragrunt-orchestrated multi-environment platform**
The key flows are: shared foundational infrastructure first, then dependent application services, then automation around validation, CI, and drift detection.
