Project 01: Cloud Infrastructure & System Architecture

“Building resilient cloud systems with zero drift and cryptographically verified boundaries.”

An in-depth case study and architectural documentation of Project 01. This space is prepared for rewriting and adding high-resolution topology diagrams directly from Ghost CMS.

System Architecture & Objectives

Project 01 focuses on building a production-grade, highly available cloud environment from first principles. The platform enforces strict declarative state management, zero-trust IAM boundaries, and containerized runtime orchestration.

Key architectural objectives include deterministic reproducible deployments, automated canary traffic validation, and zero-downtime operational lifecycles across AWS and Kubernetes.

Core Infrastructure Implementation

Infrastructure as Code is authored using modular, decoupled Terraform definitions with state isolation per environment branch. Ephemeral environments automatically provision on pull requests and garbage collect upon merge.

terraform/modules/platform/main.tf
hcl
module "vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "~> 5.0"

  name = "wvrner-production-vpc"
  cidr = "10.0.0.0/16"

  azs             = ["us-east-1a", "us-east-1b", "us-east-1c"]
  private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
  public_subnets  = ["10.0.101.0/24", "10.0.102.0/24", "10.0.103.0/24"]

  enable_nat_gateway = true
  single_nat_gateway = false
  enable_vpn_gateway = false

  tags = {
    Environment = "production"
    ManagedBy   = "terraform"
    Project     = "project-01"
  }
}

Verification & Continuous Delivery

CI/CD pipelines leverage GitHub Actions federated with AWS via short-lived OIDC STS tokens, eliminating permanent credential storage and ensuring verifiable audit trails for every infrastructure release.
