Infrastructure Cost Optimization Overview

Reduce infrastructure costs through intelligent resource allocation, reserved instances, spot instances, and continuous optimization without sacrificing performance.

When to Use Cloud cost reduction Budget management and tracking Resource utilization optimization Multi-environment cost allocation Waste identification and elimination Reserved instance planning Spot instance integration Implementation Examples 1. AWS Cost Optimization Configuration

Cost Optimization Strategies ✅ DO Use reserved instances for baseline Leverage spot instances Right-size resources Monitor cost trends Implement auto-scaling Use multi-region pricing Tag resources consistently Schedule non-essential resources ❌ DON'T Over-provision resources Ignore unused resources Neglect cost monitoring Run all on-demand Forget to release EIPs Mix cost centers Ignore savings opportunities Deploy without budgets Cost Saving Opportunities Reserved Instances: 40-70% savings Spot Instances: 70-90% savings Committed Use Discounts: 25-55% savings Right-sizing: 10-30% savings Resource cleanup: 5-20% savings Resources AWS Cost Optimization GCP Cost Optimization Azure Cost Management Kubernetes Cost Optimization
