Cloud Architecture Design Workbench
Design production-ready cloud architectures with cost and risk analysis
What You Can Do
You can design scalable, secure, and cost-effective cloud architectures tailored to your specific business requirements. The skill provides trade-off analysis across AWS, GCP, and Azure, generates detailed cost models with ROI projections, and produces stakeholder-ready documentation including architecture diagrams, risk assessments, and migration roadmaps. You'll move from vague cloud strategy to a documented, validated design ready for implementation.
Features
evaluate AWS, GCP, Azure across cost, performance, and compliance dimensions
document architectural decisions with explicit pros/cons and decision rationale
build transparent cost projections including compute, storage, networking, and operational overhead
design resilience strategies (RTO/RPO) with implementation steps
map cloud services to regulatory requirements (SOC 2, HIPAA, GDPR)
generate ASCII and visual-ready documentation from structured descriptions
plan capacity growth, auto-scaling strategy, and elasticity triggers
distill technical designs into business-focused presentation outlines
Example Output
Architecture Decision Record:
Decision: Use AWS ECS on Fargate vs. EKS vs. Lambda
Context: Microservices deployment for 50M daily requests
Option 1: ECS Fargate
- Estimated cost: $24K/month (reserved instances)
- Pros: Simpler operations, AWS-managed, good for medium workloads
- Cons: Less flexible scaling, vendor lock-in
Option 2: EKS
- Estimated cost: $28K/month
- Pros: Portability, powerful auto-scaling, large ecosystem
- Cons: Operational complexity, requires Kubernetes expertise
Recommendation: ECS Fargate
Rationale: Team has AWS-specific skills, time-to-market critical, cost advantage
Disaster Recovery Matrix:
| Tier | Service | RTO | RPO | Strategy |
|---|---|---|---|---|
| Critical | API Gateway | 5 min | 1 min | Multi-region active-active |
| High | Database | 15 min | 5 min | Cross-region replication |
| Medium | Cache | 1 hour | N/A | Read-only fallback |
Cost Projection Summary:
- Current (on-premises): $180K/month
- Proposed cloud: $98K/month (45% savings)
- Break-even: 8 months
- 3-year TCO improvement: $2.96M
