# Cloud Cost Estimator Skill

Estimates cloud costs for migration targets, provides resource sizing recommendations, and suggests cost optimization strategies.

## Purpose

Enable cloud cost planning for:
- Resource sizing recommendations
- Cost projection
- Reserved instance optimization
- Spot instance eligibility
- Cost comparison

## Capabilities

### 1. Resource Sizing Recommendations
- Right-size compute instances
- Optimize storage allocation
- Plan memory requirements
- Size database instances

### 2. Cost Projection
- Monthly cost estimates
- Annual projections
- Growth modeling
- Budget forecasting

### 3. Reserved Instance Optimization
- Identify RI candidates
- Calculate savings
- Plan commitment levels
- Optimize coverage

### 4. Spot Instance Eligibility
- Assess workload suitability
- Estimate availability
- Calculate savings
- Plan fallback strategy

### 5. Cost Comparison (On-Prem vs Cloud)
- Calculate current costs
- Project cloud costs
- Analyze TCO
- Document savings

### 6. FinOps Recommendations
- Identify waste
- Suggest optimizations
- Plan tagging strategy
- Implement showback
