AWS Cost Optimization Tips: Boost Efficiency and Save

Discover top AWS cost optimization strategies. From EC2 upgrades to S3 storage solutions, cut expenses without compromising performance.

Are you running your business on Amazon Web Services (AWS)? If so, you’re likely aware of the importance of cost optimization. AWS offers a wide range of services, and managing your expenses effectively can significantly impact your bottom line. In this blog, we’ll explore some generic but highly effective cost optimization tricks that work for most AWS customers. By implementing these strategies, you can boost efficiency and save on your AWS bills.

1. Upgrade EC2 Instances: Begin your cost optimization journey by reviewing your Elastic Compute Cloud (EC2) instances. Are you still using previous-generation instances? If so, consider upgrading them to the latest generation. Additionally, assess whether your workloads can support Graviton2-powered instances, which offer similar or better performance at a lower cost. You can use the EC2 Instance Explorer or Compute Optimizer to find the right instance types for your needs.
2. Evaluate NAT Gateway Costs: Check the cost of NAT Gateway under the EC2 section. If it’s significant, think about removing NAT Gateway from non-critical private subnets and using a t3.nano NAT Instance instead. While it may be less highly available, it comes at a much lower cost, making it a viable option for non-critical workloads.
3. Upgrade EBS Volumes: Review your Elastic Block Store (EBS) volumes. If you’re using gp2 volumes, consider upgrading to gp3 volumes. Gp3 volumes offer better performance at approximately 20% lower cost and can be upgraded in place, minimizing disruption.
4. Provisioned IOPS vs. gp3: Check if you’re using provisioned IOPS and io1 volumes in the EBS volumes section. Many workloads that previously required io1 volumes can now run on gp3 volumes with IOPS provisioned separately from storage, reducing costs.
5. Manage EBS Snapshots: Assess your spending on EBS Snapshots. If it’s significant, review the list of snapshots in the EBS section. Identify duplicate or unnecessary snapshots and delete them. Some third-party tools may create multiple snapshots that you’re unaware of, so keep an eye out for those.
6. Review Unattached EBS Volumes: While in the EBS console, check the list of EBS volumes. Are there unattached volumes not associated with any EC2 instances? Review them, take snapshots if needed, and delete them to free up resources and reduce costs.
7. Optimize S3 Storage: Examine the Simple Storage Service (S3) section of your bill. If you’re using only S3-Standard tier and have a significant amount of storage (several TB), consider enabling Intelligent Tiering or manually adding lifecycle rules to transition lesser-used objects to Infrequent Access and Glacier storage classes, which are more cost-effective.
8. Consolidate ALBs: In the Elastic Load Balancing section, review the usage pattern of your Application Load Balancers (ALBs). Determine whether you truly need all of them. Consolidate traffic using Host-based routing and Path-based routing to reduce hourly costs associated with running multiple ALBs.
9. DynamoDB Capacity Optimization: If your DynamoDB costs are substantial, evaluate your usage of On-Demand Read and Write capacity. If your usage pattern is predictable, consider moving to Provisioned Capacity, which can be more cost-effective in the long run.
10. Monitor SageMaker Expenses: Check the SageMaker section for high costs. SageMaker RunInstances can be costly if instances are provisioned for testing purposes and not shut down afterward. Given the power of SageMaker instances, costs can add up quickly.
11. Data Transfer Costs: Investigate the Data Transfer section for large regional data transfer costs. If data is being transferred between Virtual Private Clouds (VPCs) in different regions, set up VPC Peering, which is more cost-efficient than transferring data over the internet.
12. EC2 Spot Instances: Lastly, assess whether you can leverage EC2 Spot instances for certain workloads. Spot instances are ideal for workloads that are spiky, stateless, fault-tolerant, time-flexible, such as CI/CD, machine learning, pre-production, batch processing, container-based applications, high-performance computing (HPC), and web applications. Using Spot instances can significantly reduce your AWS expenses.

In conclusion, optimizing your AWS costs is a continuous process that requires regular assessment and adjustment. By following these cost optimization tricks, you can maximize your AWS resources’ efficiency while minimizing your expenses, ultimately enhancing your business’s bottom line. Start implementing these strategies today and watch your AWS bills decrease without compromising performance.
