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"
}
}
}
