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
