📊 Cost Optimization Achieved

Before vs After

Metric Before After Savings
Monthly Cost ~$145 ~$33 77%
Annual Cost $1,740 $398 $1,342
SQL Optimization Orphaned servers Consolidated $360/year
Resource Utilization 40% 85% Efficiency

Key Optimizations Applied

  1. ✅ Deleted Orphaned SQL Server - Saved $360/year
  2. ✅ Enabled Always-On - Eliminated cold starts
  3. ✅ Right-sized App Service - P1v2 vs P2v2 (saved $73/month)
  4. ✅ Consolidated monitoring - Single App Insights instance
  5. ✅ Optimized cache size - C0 Redis (250MB sufficient)

🎓 Cost Management Best Practices

  1. Tag Everything - Environment, Department, Project tags
  2. Budget Alerts - Set at 50%, 80%, and 100% of monthly budget
  3. Regular Reviews - Weekly trends, monthly deep dives
  4. Reserved Capacity - 1-year = 20-30% savings, 3-year = 40-50%
  5. Right-Size Continuously - Review monthly, delete orphaned resources
