Usage Examples

Example 1: Savings Plan Impact Modeling (5 min)

runbooks finops scenario \
  --type savings-plan \
  --all-profiles \
  --format pdf

# Output: Executive summary:
# Current Baseline: $125K/month ($1.5M annual)
# 
# Strategy 1: 1-Year Savings Plan
#   - Monthly cost: $106K (-$19K = -15%)
#   - Annual savings: $228K
#   - Upfront commitment: $1.27M
#   - ROI: Positive (19% annual savings)
#
# Strategy 2: 3-Year Savings Plan
#   - Monthly cost: $88K (-$37K = -30%)
#   - Annual savings: $444K
#   - Upfront commitment: $3.17M
#   - ROI: Excellent (30% annual savings)
#
# Recommendation: 3-year SP (maximize savings + budget certainty)

Example 2: Multi-Strategy Comparison (10 min)

runbooks finops optimize \
  --all-profiles \
  --compare-strategies \
  --format pdf \
  --output-dir ./scenarios

# Output: Scenario comparison:
# Baseline: $125K/month
# Decommission only: $112K (-10%)
# Savings Plan only: $106K (-15%)
# Decommission + SP: $94K (-25%)
# Decommission + SP + Optimization: $88K (-30%)
#
# Recommendation: Combine all 3 for maximum impact

Example 3: Per-Service Optimization Strategy (15 min)

runbooks finops scenario \
  --breakdown-by-service \
  --all-profiles \
  --format csv

# Output: Per-service recommendations:
# EC2-Other:
#   - Current: $24.5K/month
#   - Decommission: -$6K (25%)
#   - Right-size: -$3K (12%)
#   - SP discount: -$5K (20%)
#   - Total: $10.5K (-57% potential)
#
# RDS:
#   - Current: $16.4K/month
#   - Consolidation: -$3K (18%)
#   - RI discount: -$4K (24%)
#   - Total: $9.4K (-43% potential)
