Quick navigation
Your AWS bill keeps growing. Every month brings new surprise charges, and you're not even sure what's driving the costs.
Sound familiar? You're not alone. Most organizations waste 30-50% of their cloud spend on unused resources, oversized instances, and inefficient configurations.
But here's the good news: you can cut that waste fast. Really fast.
I've helped hundreds of companies reduce their AWS costs, and the pattern is always the same. The biggest savings come from fixing obvious problems first, then optimizing systematically.
This guide shows you exactly how to do it. No theory. No fluff. Just specific actions that deliver measurable results.
Quick win alert
Before diving in, check your AWS Trusted Advisor right now. Look for the "Low Utilization Amazon EC2 Instances" check. Stopping just 2-3 idle instances could save you $500+ this month.
Week 1: Immediate wins (Days 1-7)
Start here. These actions deliver instant savings with minimal risk.
Days 1-2: Stop the bleeding
Find and eliminate obvious waste. This typically saves 10-15% immediately.
Action checklist:
- □ Identify idle EC2 instances (CPU utilization under 5% for 7 days)
- □ Find unattached EBS volumes and snapshots
- □ Locate unused Elastic IPs and NAT Gateways
- □ Review Load Balancers with no active targets
AWS Console Steps:
- Go to EC2 → Instances → Sort by "State" and "Launch time"
- Check CloudWatch metrics for CPU utilization over past 7 days
- Go to EC2 → Volumes → Filter by "Available" status
- Review each resource before terminating (check with teams first)
Expected savings: $2,000-5,000/month for typical mid-size deployments
Days 3-4: Quick storage wins
Storage costs add up fast. Simple changes here deliver big savings.
Storage optimization tasks:
- □ Move old S3 data to Intelligent Tiering (saves 20-40%)
- □ Delete incomplete multipart uploads
- □ Switch gp2 EBS volumes to gp3 (20% cheaper)
- □ Review EBS snapshot retention policies
Quick tip:
Use S3 Storage Lens to identify buckets with the highest costs. Focus your optimization efforts there first for maximum impact.
Days 5-7: Database optimization
Database instances are often oversized. Right-sizing saves 15-30% immediately.
Database Type | Common Issue | Quick Fix | Savings |
---|---|---|---|
RDS MySQL/PostgreSQL | Oversized instances | Monitor CPU, downsize | 20-40% |
DynamoDB | Provisioned capacity | Switch to on-demand | 25-50% |
ElastiCache | Unused clusters | Audit usage, terminate | 100% |
Redshift | Always-on clusters | Pause when not in use | 60-80% |

Schedule a 15-minute demoWeek 2: Right-sizing and optimization (Days 8-14)
Now we dig deeper. These optimizations require more analysis but deliver bigger savings.
EC2 right-sizing methodology
Most EC2 instances are oversized by 40-60%. Here's how to fix it systematically.
Step 1: Gather data
- • 14 days of CloudWatch metrics
- • CPU, memory, network utilization
- • Peak usage patterns
- • Application performance requirements
Step 2: Right-size rules
- • CPU under 40%? Consider smaller instance
- • Memory under 60%? Check memory optimized
- • Network under 25%? Downgrade bandwidth
- • Always test in staging first
Pro tip:
Use AWS Compute Optimizer recommendations, but verify them. The tool sometimes suggests undersized instances. Always check your application's specific requirements.
Auto Scaling optimization
Proper scaling policies can reduce costs by 30-50% while improving performance.
Scaling best practices:
- Scale out, not up: Use multiple smaller instances instead of fewer large ones
- Predictive scaling: Use scheduled scaling for known traffic patterns
- Spot instances: Replace up to 70% of on-demand instances with Spot
- Mixed instance types: Use different sizes to handle varying workloads
Workload Type | Recommended Mix | Potential Savings |
---|---|---|
Web applications | 50% On-Demand, 50% Spot | 35-45% |
Batch processing | 20% On-Demand, 80% Spot | 55-65% |
Development/testing | 100% Spot (with automation) | 70-80% |
Network optimization
Data transfer costs are often overlooked but can be reduced significantly.
Cross-AZ charges
$0.01-0.02 per GB between Availability Zones. Minimize by keeping related services in same AZ.
Internet egress
$0.09 per GB to internet. Use CloudFront CDN to reduce origin requests by 80-90%.
VPC endpoints
$0.01 per hour + $0.01 per GB. Usually cheaper than NAT Gateway for AWS services.
Week 3: Storage and data transfer optimization (Days 15-21)
Storage often represents 20-30% of total AWS costs. Small optimizations here create big savings.
S3 cost optimization deep dive
Storage class decision tree:
- • Daily access: S3 Standard ($0.023/GB/month)
- • Weekly access: S3 Standard-IA ($0.0125/GB/month)
- • Monthly access: S3 Glacier Instant Retrieval ($0.004/GB/month)
- • Quarterly access: S3 Glacier Flexible Retrieval ($0.0036/GB/month)
- • Yearly+ access: S3 Glacier Deep Archive ($0.00099/GB/month)
- • Unknown pattern: S3 Intelligent-Tiering (automatic optimization)
Implementation priority
- Enable Intelligent-Tiering on all buckets (set it and forget it)
- Create lifecycle policies for predictable data (logs, backups)
- Delete incomplete multipart uploads older than 7 days
- Review and clean up old versions if versioning is enabled
Data Type | Optimization Strategy | Savings Potential |
---|---|---|
Application logs | Lifecycle to Glacier after 30 days | 80-85% |
Database backups | Glacier Deep Archive after 90 days | 90-95% |
Media files | Intelligent-Tiering with CloudFront | 40-60% |
User uploads | Standard-IA after 30 days | 45-50% |
EBS volume optimization
EBS costs can be reduced by 20-40% with the right volume types and configurations.
Volume type migration
- gp2 → gp3: 20% cost savings, better performance
- io1 → io2: 40% cost savings for same IOPS
- st1 → gp3: Consider for better random I/O
- Magnetic → gp3: 50%+ savings with better performance
Right-sizing volumes
- Monitor disk utilization over 30 days
- Look for volumes under 80% capacity
- Consider EBS Elastic Volumes for resizing
- Remove unused snapshots older than 30 days
Migration tip:
EBS volume modifications can be done online without downtime. Start with non-critical instances to test the process, then batch modify similar volumes.
Data transfer cost reduction
Data transfer can account for 10-20% of your bill. Here's how to minimize it.
CloudFront optimization
Enable compression, optimize cache behaviors, use regional edge caches. Can reduce origin requests by 85-95%.
VPC Peering vs Transit Gateway
VPC Peering: $0.01/GB. Transit Gateway: $0.02/GB + hourly charges. Peering is cheaper for simple connections.
Direct Connect benefits
Dedicated connection reduces data transfer costs by 30-50% for high-volume workloads (>5TB/month).
Week 4: Advanced optimization strategies (Days 22-30)

Frequently asked questions
Can I really reduce AWS costs by 30% in 30 days?
Yes, most organizations can achieve 20-40% cost reduction within 30 days by implementing right-sizing, eliminating waste, and optimizing storage. The key is following a systematic approach and addressing the biggest cost drivers first. Companies with significant waste (unused resources, oversized instances) often see even higher savings.
What's the fastest way to see immediate AWS savings?
The fastest savings come from stopping unused resources (idle EC2 instances, unattached EBS volumes), right-sizing oversized instances, and switching to cheaper storage classes. These changes can be implemented within hours and show immediate results on your next bill. Focus on Trusted Advisor recommendations first for quick wins.
Do I need technical expertise to implement these cost reduction strategies?
Most strategies require basic AWS console navigation skills. The first week's optimizations (stopping unused resources, basic right-sizing) can be done by anyone with AWS access. However, advanced optimizations like Reserved Instance planning, Auto Scaling configuration, and Spot instance implementation benefit from technical expertise or tools like RightSpend that handle the complexity automatically.
How much can commitment-free discounts save compared to Reserved Instances?
Commitment-free discounts typically provide 15-20% savings without upfront commitments or capacity restrictions, compared to 20-72% with Reserved Instances. The advantage is flexibility and no financial risk if your usage patterns change. For dynamic environments or growing companies, commitment-free options often provide better total value despite lower discount percentages.
What tools help automate AWS cost optimization?
AWS native tools include Cost Explorer, Trusted Advisor, and Compute Optimizer for recommendations. However, these require manual implementation of suggestions. Third-party solutions like RightSpend provide advanced automation, commitment-free discounts, and continuous optimization without manual intervention. The best approach combines both: use native tools for analysis and automation platforms for implementation.
Is it safe to make all these changes quickly?
Yes, when done methodically. Start with obvious waste elimination (unused resources) which carries no risk. For right-sizing and architectural changes, always test in non-production environments first. Implement changes during maintenance windows and have rollback plans. The guide prioritizes low-risk optimizations first, then builds to more complex strategies as you gain confidence.
How do I maintain savings after the initial 30-day optimization?
Sustainable cost optimization requires ongoing monitoring and automation. Set up Cost Budget alerts, review monthly reports, and implement governance policies to prevent cost creep. Automated solutions like RightSpend provide continuous optimization without manual oversight. Regular reviews (quarterly) help identify new optimization opportunities as your infrastructure evolves.
Which AWS instances should I downsize first?
Start with instances showing consistently low CPU utilization (under 20%) over 30+ days. Look for development, testing, and staging environments that often run oversized. Production instances require more careful analysis, but those with steady low utilization are good candidates for downsizing. Always test changes during maintenance windows with rollback plans ready.
Can small businesses save 30% on AWS costs too?
Yes, small businesses often have the highest optimization potential since they may lack dedicated AWS expertise. Common savings areas include unused development resources, oversized databases, and expensive storage classes for infrequently accessed data. Small businesses can achieve 30-50% savings by following the basic optimization steps in the first two weeks of this guide.
Should I use Reserved Instances or Savings Plans?
For predictable, steady workloads, Reserved Instances offer maximum savings (up to 75%). Savings Plans provide more flexibility across instance types and regions with slightly lower discounts (up to 66%). However, Commitment Free Discounts offer 20-55% savings without any long-term commitment, making them ideal for growing or variable workloads.
What happens if I make a mistake during optimization?
Most AWS changes are reversible. Instance resizing can be undone, stopped instances can be restarted, and storage classes can be changed back. Always take snapshots before major changes, test in non-production first, and implement during low-traffic periods. Start with low-risk optimizations like stopping unused resources before moving to architectural changes.
How do I know which storage class to use?
Use S3 Standard for frequently accessed data, S3 IA for data accessed monthly, Glacier for long-term archival, and Glacier Deep Archive for compliance data. Implement S3 Intelligent Tiering to automatically move data between classes. For EBS volumes, use gp3 instead of gp2 for better performance at lower cost, and consider st1/sc1 for throughput-intensive workloads.
