Execution Flow

┌──────────────────────────────────────────────────────────┐
│ 1. VALIDATE: Check workload and requirements              │
│ 2. ANALYZE: Workload characteristics                      │
│ 3. SELECT: Cloud services for each component              │
│ 4. DESIGN: Architecture diagram                           │
│ 5. ESTIMATE: Cost projection                              │
│ 6. OPTIMIZE: Apply cost/performance optimizations         │
│ 7. DOCUMENT: Return architecture with IaC snippets        │

Unit Test Template

test_cases:
  - name: "Web app on AWS"
    input:
      workload: "E-commerce web application with 10K daily users"
      provider: "aws"
      architecture_type: "containers"
    expected:
      has_services: true
      has_diagram: true
      has_cost_estimate: true
      services_include: ["ECS", "RDS", "CloudFront"]

  - name: "Serverless API"
    input:
      workload: "RESTful API with variable traffic"
      provider: "aws"
      architecture_type: "serverless"
    expected:
      services_include: ["Lambda", "API Gateway", "DynamoDB"]

  - name: "Budget exceeded"
    input:
      workload: "Enterprise data warehouse"
      requirements: { "monthly_budget_usd": 100 }
    expected:
      warning: "budget_exceeded"
      has_alternatives: true

Troubleshooting

Common Issues

Symptom	Root Cause	Resolution
High cost estimate	Wrong service tier	Right-size, use reserved
Single point of failure	Missing HA design	Add multi-AZ, redundancy
Vendor lock-in warning	Proprietary services	Use portable alternatives

Debug Checklist

□ Is provider selection appropriate?
□ Are availability requirements met?
□ Is cost within budget?
□ Are all components connected?
□ Is IaC syntax valid?

Service Quick Reference

Component	AWS	Azure	GCP
Compute	ECS/Lambda	AKS/Functions	GKE/Cloud Functions
Database	RDS/Aurora	SQL Database	Cloud SQL
Storage	S3	Blob Storage	Cloud Storage
Cache	ElastiCache	Cache for Redis	Memorystore

---

Integration

Component	Trigger	Data Flow
Agent 04	Design request	Receives workload, returns architecture
Agent 05	Security review	Provides security requirements

---

Quality Standards

• Cost-aware: Always include estimates
• HA by default: Multi-AZ unless specified
• IaC-ready: Include Terraform/CloudFormation snippets
