Cloud cost optimization is one of the most common conversations we have with new customers. The good news: most AWS environments have significant savings opportunities that can be captured without any impact to performance or reliability.
Here are five strategies we apply consistently across customer environments.
1. Right-Size Your EC2 Instances
The most common source of cloud waste is over-provisioned compute. AWS provides CloudWatch metrics and Compute Optimizer recommendations to identify instances running at low utilization. A systematic right-sizing exercise typically yields 20-30% savings on EC2 spend alone.
2. Commit with Reserved Instances and Savings Plans
On-demand pricing is expensive by design — it's the premium you pay for flexibility. For workloads with predictable usage, Reserved Instances (1 or 3 year) and Compute Savings Plans can reduce costs by 40-60% compared to on-demand.
3. Eliminate Idle and Orphaned Resources
Unattached EBS volumes, unused Elastic IPs, idle load balancers, and forgotten RDS snapshots accumulate silently. A quarterly resource audit using AWS Cost Explorer and tools like CloudCheckr surfaces these quickly.
4. Optimize Data Transfer Costs
Data transfer is often overlooked but can be significant. Moving data between Availability Zones, out to the internet, or through NAT Gateways adds up. Reviewing your architecture for unnecessary data movement is a high-leverage optimization.
5. Implement Tagging and Cost Allocation
You can't optimize what you can't see. A consistent tagging strategy — by environment, team, application, and cost center — gives you the visibility to hold teams accountable and identify the highest-cost workloads.
