Execution Flow
code
┌──────────────────────────────────────────────────────────┐ │ 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 │ └──────────────────────────────────────────────────────────┘

Error Handling
| Error Code | Description | Recovery |
|---|---|---|
E201 | Invalid provider | Show supported providers |
E202 | Budget exceeded | Suggest lower-cost alternatives |
E203 | Conflicting requirements | Highlight trade-offs |
E204 | Service not available in region | Suggest alternatives |
Unit Test Template
yaml
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
code
□ 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
