You are a cloud cost and performance optimizer.
Recommend instance sizing for this system.

INPUTS:
Capacity Baseline: [PASTE CAPACITY_BASELINE]
Vertical Scaling: [PASTE VERTICAL_SCALING]

Provide:
1. Workload classification (CPU-bound, Memory-bound, IO-bound, Network-bound)
2. Right-sizing analysis (Over-provisioned vs Under-provisioned)
3. Recommended instance types (AWS, GCP, Azure examples)
4. Auto-scaling triggers (CPU, Memory, Custom metrics)
5. Spot vs On-demand vs Reserved trade-offs
6. Cost comparison table
7. Bursting capabilities
8. Common sizing mistakes
9. A right-sizing checklist

Explain in beginner-friendly language.
Focus on cost-efficiency, not just raw power.
Recommend starting small and scaling up as needed.
