Why EC2 Cost Optimization Matters
EC2 instances are often the largest contributor to AWS bills, accounting for up to 45% of total cloud spend for many organizations. Optimizing these costs not only improves your bottom line but also aligns your infrastructure with AWS best practices for efficiency and scalability. Whether you’re a startup scaling rapidly or an enterprise managing complex workloads, the strategies below will help you maximize value from EC2 while minimizing expenses.
10 Proven Strategies to Reduce AWS EC2 Costs
1. Right-Size Your Instances
Why It Matters
Choosing the right instance type and size is critical to avoiding overprovisioning, where you pay for unused resources, or underprovisioning, which can degrade performance. AWS Compute Optimizer uses machine learning to analyze your workloads and recommend optimal instance types based on CPU, memory, and network usage.
How to Implement
- Use AWS Compute Optimizer: Enable this free tool to get tailored recommendations for EC2 instances, EBS volumes, and Lambda functions. It identifies overprovisioned instances and suggests cost-effective alternatives, such as switching from older M5 instances to newer M6i or ARM-based Graviton instances, which can save up to 20% on compute costs.
- Analyze Workload Patterns: Review Compute Optimizer’s recommendations in the AWS Console to identify instances with low CPU or memory utilization. For example, downsizing from a t3.large to a t3.medium can reduce costs without impacting performance for lightly loaded applications.
- Test New Instance Types: Experiment with Graviton3 processors, which offer up to 40% better price-performance than comparable x86 instances.
Cloudvisor Pro Tip
Schedule regular reviews (e.g., monthly) with Compute Optimizer to adapt to changing workloads. Our clients have saved up to 30% on EC2 costs by implementing these recommendations alongside our free Cost Optimization Reviews. Book a consultation at cloudvisor.co to get started.
2. Leverage Spot Instances for Flexible Workloads
Why It Matters
EC2 Spot Instances allow you to use spare AWS capacity at discounts of up to 90% compared to On-Demand pricing. They’re ideal for fault-tolerant, stateless, or flexible workloads like big data processing, CI/CD pipelines, or batch jobs.
How to Implement
- Identify Suitable Workloads: Use Spot Instances for non-critical workloads that can tolerate interruptions, such as development environments, machine learning training, or containerized applications.
- Use Spot Fleet or Elastigroup: Spot Fleet diversifies instance types to reduce interruption risk, while third-party tools like Spot.io’s Elastigroup provide AI-driven interruption prediction and auto-recovery for mission-critical workloads.
- Combine with Auto Scaling: Integrate Spot Instances into Auto Scaling groups to automatically replace interrupted instances with On-Demand or other Spot Instances, ensuring continuity.
Pro Tip

3. Commit to Savings Plans or Reserved Instances for Predictable Workloads
Why It Matters
For stable, long-term workloads, Savings Plans and Reserved Instances (RIs) offer discounts of up to 72% compared to On-Demand pricing. Savings Plans are more flexible, covering EC2, Lambda, and Fargate, while RIs are ideal for specific EC2 instance families or services like RDS and Redshift.
How to Implement
- Choose the Right Model: Opt for Compute Savings Plans for flexibility across instance types and regions, or EC2 Instance Savings Plans for specific families. RIs are best for highly predictable workloads, such as database servers.
- Analyze Usage with AWS Cost Explorer: Use Cost Explorer to identify consistent usage patterns and estimate savings from committing to a 1- or 3-year plan.
- Avoid Overcommitment: Start with a smaller commitment and scale up as you gain confidence in your usage patterns. Cloudvisor’s cost optimization consultations can guide you through this process.
Pro Tip
Combine Savings Plans with our AWS Activate program support to access up to $100,000 in credits, offsetting commitment costs and boosting savings.
4. Implement Auto Scaling for Dynamic Workloads
Why It Matters
AWS Auto Scaling adjusts instance capacity based on demand, ensuring you only pay for what you need during peak and off-peak periods. This is especially effective for applications with variable traffic, like e-commerce platforms or streaming services.
How to Implement
- Configure Auto Scaling Groups (ASGs): Set up ASGs to scale instances based on metrics like CPU utilization, request rates, or custom CloudWatch metrics. For example, scale out during peak hours and scale in overnight.
- Use Predictive Scaling: AWS’s Predictive Scaling forecasts demand using machine learning, proactively adjusting capacity to avoid overprovisioning.
- Integrate with Elastic Load Balancing: Distribute traffic across instances to optimize performance and reduce the need for excess capacity.
Pro Tip
Our DevOps experts can automate your scaling policies using CloudFormation templates, saving you time and ensuring cost-efficient scaling. Request a free Well-Architected Framework Review to optimize your ASGs.
5. Optimize Storage Costs for EC2 Instances
Why It Matters
Elastic Block Store (EBS) volumes and snapshots can quietly accrue costs, even for stopped instances. Optimizing storage ensures you’re not paying for unused or inefficient resources.
How to Implement
- Switch to gp3 Volumes: Migrate from gp2 to gp3 EBS volumes for up to 20% cost savings and better performance.
- Delete Unused EBS Volumes and Snapshots: Use AWS Trusted Advisor or CloudWatch to identify unattached EBS volumes or stale snapshots, and automate cleanup with Lambda functions.
- Enable Delete on Termination: Ensure EBS volumes are set to delete when their associated EC2 instance is terminated to avoid lingering costs.
Pro Tip

6. Schedule Instances with AWS Instance Scheduler
Why It Matters
Non-production environments, like development or testing instances, don’t need to run 24/7. Scheduling instances to stop during idle periods can cut costs by up to 75% for those workloads.
How to Implement
- Use AWS Instance Scheduler: Configure schedules to start and stop EC2 and RDS instances based on business hours or workload needs.
- Tag Resources: Apply tags (e.g., “Environment: Dev”) to group instances for scheduling, making it easier to manage multiple resources.
- Monitor Compliance: Use AWS Budgets to set alerts for unscheduled instances running outside designated hours.
Pro Tip
Cloudvisor’s automation expertise can streamline Instance Scheduler setup, ensuring your non-production environments are cost-optimized without manual intervention.
7. Monitor and Analyze Costs with AWS Tools
Why It Matters
Visibility into your EC2 usage is critical for identifying cost-saving opportunities. AWS provides robust tools to track, analyze, and forecast spending, helping you stay within budget.
