Cost Optimization

FinOps Principles

Visibility - Know what you spend
Optimization - Reduce waste
Governance - Control growth

Quick Wins

| Action | Savings | |--------|---------| | Reserved instances | 30-70% | | Spot instances | 60-90% | | Rightsizing | 20-40% | | Unused resources | 100% | | Storage tiering | 50-80% |

Rightsizing

# AWS: Find underutilized instances
aws cloudwatch get-metric-statistics \
  --namespace AWS/EC2 \
  --metric-name CPUUtilization \
  --dimensions Name=InstanceId,Value=i-xxx \
  --start-time 2024-01-01T00:00:00Z \
  --end-time 2024-01-31T00:00:00Z \
  --period 86400 \
  --statistics Average

If CPU < 20% avg: Downsize or use smaller instance.

Reserved vs Spot

| Workload | Recommendation | |----------|----------------| | Steady baseline | Reserved (1-3 year) | | Variable load | On-demand + Spot | | Batch processing | Spot | | Stateless services | Spot with fallback |

Storage Optimization

# S3 Lifecycle
resource "aws_s3_bucket_lifecycle_configuration" "main" {
  bucket = aws_s3_bucket.main.id

  rule {
    id     = "archive"
    status = "Enabled"

    transition {
      days          = 30
      storage_class = "STANDARD_IA"
    }

    transition {
      days          = 90
      storage_class = "GLACIER"
    }
  }
}
