Optimization
Implement cost optimization strategies to reduce cloud spending without sacrificing performance.
Optimization Strategies
Reserved Instances
Convert On-Demand instances to Reserved Instances for 30-60% savings:
- Standard Reserved Instances: Highest discount, fixed instance type
- Convertible Reserved Instances: Lower discount, flexible instance types
- 1-Year or 3-Year Terms: Longer commitment = higher savings
Best For: Stable, predictable workloads running 24/7
Savings Plans
Flexible pricing model based on compute usage commitment:
- Compute Savings Plans: Most flexible, any instance family
- EC2 Instance Savings Plans: Higher discount, specific instance family
- SageMaker Savings Plans: For ML workloads
Best For: Workloads with variable instance types but consistent compute usage
Right-Sizing
Downsize overprovisioned resources:
- Analyze CPU, memory, and disk utilization
- Identify instances with < 20% average utilization
- Recommend smaller instance types
- Test and validate before applying changes
Potential Savings: 20-40% on compute costs
Spot Instances
Use spare EC2 capacity at up to 90% discount:
- Best For: Batch jobs, data processing, fault-tolerant workloads
- Not Recommended For: Production databases, stateful applications
- Combine with On-Demand for mixed fleet strategy
Auto-Scaling
Automatically adjust capacity based on demand:
- Scale out during high traffic periods
- Scale in during low traffic periods
- Set minimum and maximum instance counts
- Use metrics-based or schedule-based scaling
Potential Savings: 30-50% by matching capacity to demand
Storage Optimization
Reduce storage costs through lifecycle management:
- S3 Intelligent Tiering: Automatically move objects between access tiers
- Glacier Archive: Move old data to low-cost archive storage (90% savings)
- EBS Snapshot Cleanup: Delete old or unused snapshots
- Unattached Volume Cleanup: Remove volumes not attached to instances
Automated Scheduling
Stop non-production resources during off-hours:
Development Environment Schedule
- Weekdays: 8 AM - 7 PM (11 hours/day)
- Weekends: Stopped
- Savings: 60-70% on development compute costs
Staging Environment Schedule
- Business Hours: 6 AM - 10 PM (16 hours/day)
- Weekends: Limited hours or stopped
- Savings: 30-40% on staging compute costs
Implementation
- Tag resources with
environment:devorenvironment:staging - Configure schedule in FinOps → Settings → Automated Scheduling
- Exclude critical resources with
cost-optimization:excludetag - Monitor savings in FinOps dashboard
Continuous Optimization
Best practices for ongoing cost management:
- Weekly Reviews: Check cost trends and anomalies
- Monthly Optimization: Apply new recommendations
- Quarterly Analysis: Review Reserved Instance coverage
- Annual Planning: Adjust budgets and optimization strategies
Start with quick wins (unused resources, automated scheduling) for immediate savings, then implement long-term strategies (Reserved Instances, Savings Plans) for sustained cost reduction.
