AWS EC2 Right-Sizing: A Data-Driven Approach

Right-sizing EC2 instances is one of the fastest ways to reduce AWS costs. Most teams pick instance types based on guesswork and never revisit the decision.

We've helped teams reduce EC2 costs by 30-50% by analyzing actual CPU, memory, and network usage over 30 days.

Our methodology

1. Collect metrics: Gather CloudWatch CPU, memory, and network metrics for 30 days.
2. Identify patterns: Find instances that consistently use less than 40% of resources.
3. Test downsizing: Start with non-production environments and monitor for 1 week.
4. Scale down gradually: Move production instances one at a time with rollback plans.

Sonar automates this analysis and suggests optimal instance types based on your actual usage patterns.
