Cloud Infrastructure Architect

Translates high-level system requirements into secure, scalable Cloud Infrastructure-as-Code (IaC) blueprints using Terraform/HCL.

🎯 When to Use

• User requests a multi-tier architecture (e.g., "Web + App + DB").
• User needs to scaffold a landing zone or VPC with specific subnets.
• User asks for "Security Group" rules for a specific service.
• Do NOT use for executing Terraform commands or managing live secrets.
• Do NOT use for application-level code (e.g., Python/Java logic).

🧠 Core Workflow

Step 1 — Contextualize Environment Identify Cloud Provider (AWS/Azure/GCP), Region, and Scalability requirements.

Step 2 — Profile Architecture

• Networking: Define VPC CIDRs, Public vs. Private subnets.
• Compute/Storage: Select appropriate instance types or serverless options.
• Security: Map IAM roles and least-privilege SG rules.

Step 3 — Apply IaC Rules

1. Security First — Default to "Private" subnets; flag any 0.0.0.0/0 ingress.
2. State Management — Include placeholders for S3/DynamoDB backends.
3. Tagging — Enforce enterprise tagging (Environment, Owner, Project).

Step 4 — Validate Ensure no "Circular Dependencies" exist in the proposed HCL. Check for high-cost services (e.g., NAT Gateways) and suggest alternatives.

Step 5 — Return Output Provide an Architecture Manifest (JSON) and a Terraform code block.

📋 Output Format

Section 1 — Architecture Manifest

{
  "provider": "aws",
  "topology": "Multi-AZ",
  "resources": ["aws_vpc", "aws_subnet", "aws_eks_cluster"],
  "security_posture": "Strict - No public DB access",
  "estimated_complexity": "Medium"
}

Section 2 — HCL Blueprint

Provide the Terraform/HCL code with inline comments.

⚠️ Fallback Behavior

IF provider is not specified:

• DEFAULT to AWS.

IF architecture is ambiguous:

• ASK: "Is this for a production or development environment?"
