Your first AWS bill hits different. All those services you’ve been exploring, all those resources you left running “for testing”—they add up fast.
Here’s the good news: most teams can cut their AWS spend by 30-50% with five simple changes. No architectural overhaul required.
1. Turn Off What You’re Not Using
This is the low-hanging fruit. Go through your console and look for:
- Unused EC2 instances: Stopped instances still cost money (storage, IPs). Terminate them.
- Unattached EBS volumes: Check the EBS dashboard. Delete anything not attached to an instance.
- Unused RDS databases: Database instances aren’t cheap. If it’s not serving production, delete it.
- Old snapshots: Snapshots stack up. Keep 2-3 recent ones, delete the rest.
Typical savings: 20-30% of bill
2. Use Reserved Instances for Predictable Workloads
If you have production instances that run 24/7, reserved instances can save 40% vs. on-demand pricing.
Buy 1-year or 3-year commitments for:
- Production databases
- Always-on application servers
- Monitoring and logging infrastructure
Keep on-demand for:
- Development instances
- Batch processing
- Bursty workloads
Typical savings: 10-15% of bill
3. Use S3 Intelligent-Tiering
S3 has different storage classes for different access patterns. Most teams just use standard storage and overpay.
Enable Intelligent-Tiering and AWS automatically moves data:
- Frequent access (standard): $0.023 per GB
- Infrequent access: $0.0125 per GB
- Archive: $0.004 per GB
Typical savings: 20-40% of storage costs
4. Right-Size Your Instances
Monitor your CPU and memory usage. Most teams run oversized instances “just in case.”
Use CloudWatch to see actual usage:
- If your instance is 10% CPU utilization, you’re paying 10x what you need
- Downsize to smaller instance types
- Use auto-scaling to handle spikes
Typical savings: 15-30% of compute costs
5. Set Up Billing Alerts
This isn’t a savings hack—it’s prevention. Set alerts in AWS Billing Dashboard:
- Alert if daily spend exceeds $50
- Alert if monthly forecast exceeds budget
- Catch runaway costs immediately
The Real Savings
Implementing these five changes typically saves:
- Month 1: 30-40% reduction
- Ongoing: 15-20% reduction (from better practices)
For a team spending $10k/month, that’s $3-4k saved immediately.
The best part? Most of these take less than an hour to implement.
