How to Optimize EC2 Costs on AWS?
EC2 Cost optimization helps you to optimize your cloud spending while helping you to build a scalable infrastructure that meets your demand. These EC2 cost optimization strategies effectively manage your cloud cost while maintaining the performance and capacity that you require.
Using Dedicated Hosts
A Dedicated host is a physical EC2 server that is fully reserved for your use. This is suitable for workloads looking for a dedicated physical server.
Choosing a dedicated host to run your application helps you reduce your EC2 cost by enabling you to utilize your current server-bound licenses. This helps you to reduce your licensing costs. You can purchase a Dedicated host On-demand on an hourly basis or as part of your savings plan.
Rightsizing underutilized resources
Identify the instances that have low utilization and reduce costs by stopping or rightsizing them. You can use AWS Cost Explorer Resource Optimization report to get the list of instances that are either idle or have low utilization. You can also use services like AWS Instance Scheduler to automatically stop the instances or use AWS Operations Conductor to automatically resize the instances, based on the recommendations from Cost Explorer.
Use Auto Scaling for Dynamic Workloads
Autoscaling is the technique of automatically adjusting the capacity of your EC2 instances by scaling in or scaling out the instances, based on the incoming workload. It helps to increase fault tolerance at the lowest price possible. An autoscaling group is a logical collection of EC2 instances that work together to maintain the steady performance of the application.
Choose Savings Plan over RI
Though both Savings Plan and RI are cost-saving options from AWS, Savings Plan offers more flexibility. With Savings Plan, you commit to a certain amount of usage, rather than a specific instance type or family. This allows you to apply savings to a wider range of EC2 instance types, sizes, and regions.
Savings Plan do not require capacity reservation. Thus, you need not pay for unused capacity, or be limited by instance availability in a specific AZ. Also, Savings Plan applies automatic discounts to your AWS EC2 usage, regardless of the instance type, size, family, operating system, or region.
Schedule On/Off Times for Non-Critical Instances
Not all workloads require continuous operation. By scheduling non-critical instances to shut down during off-hours, such as evenings and weekends, organizations can significantly reduce unnecessary compute costs. Tools like AWS Instance Scheduler facilitate this automation, ensuring that your AWS EC2 instances run only when necessary.
Implementing a schedule for on/off times can lead to better resource utilization and cost predictability. Businesses can analyze usage patterns to determine optimal shutdown times, aligning instance availability with actual demand. This not only minimizes costs but also frees up IT teams to focus on more strategic initiatives instead of manual resource management.
Optimize Resource Allocation with AWS EC2 Fleets
EC2 Fleet enables you to combine On-Demand, Reserved, and Spot instances into a single resource pool, allowing for optimized instance usage and cost management. This flexibility lets you balance reliability and pricing effectively, ensuring that your applications run smoothly without incurring excessive costs.
EC2 Fleetโs ability to automatically provision instances based on demand helps streamline resource allocation. By dynamically adjusting the mix of instance types, businesses can respond swiftly to changing workload requirements, further enhancing both the cost efficiency of EC2 instances and its performance.
Choose the Right Instance Type
Selecting the correct instance type is important for cost optimization. AWS offers a variety of EC2 instance families tailored for different workloads, such as compute-optimized, memory-optimized, and storage-optimized instances. By carefully analyzing your workload requirements, you can avoid over-provisioning or under-provisioning resources. For instance, running a memory-intensive application on a compute-optimized instance will lead to inefficiencies and higher costs.
Implement Elastic IP Best Practices
Elastic IPs provide static public IP addresses that are essential for certain applications, but keeping unused Elastic IPs attached to your account can lead to unnecessary costs. To optimize expenses, ensure that Elastic IPs are only associated with running instances or services that require them.
Moreover, consider adopting a policy for the efficient allocation of Elastic IPs. For example, if you frequently create and terminate instances, having a well-defined process for managing Elastic IPs can minimize waste. By implementing these best practices, you can significantly reduce costs associated with Elastic IPs while maintaining the flexibility they provide for your cloud applications.
Utilize Spot Instances
Spot instances allow you to take advantage of AWS’s unused capacity at a significantly reduced price. These instances are ideal for stateless, fault-tolerant applications or workloads with flexible start and end times. While spot instances can be interrupted with little notice, the savings can be substantial. It saves up to 90% cost compared to On-Demand pricing.
You can also make use of EC2 Spot Instance Advisor to reduce interruptions on spot instances. Spot Instance Advisor helps you find the most reliable pools of Spot Instances with the least chance of interruption, showing you how much you can save compared to On-Demand rates. This lowers the risk of interruption, aiding your Spot Instances to run longer, which helps you achieve both reliable performance and significant cost savings.
Take advantage of Per second billing
Per second billing is an EC2 cost optimization technique that removes unused minutes and seconds from your bill. This technique is useful for instances running over irregular time periods, like testing, data analytics, batch processing, etc.
EC2 utilization is billed in 1-second increments, with a minimum duration of 60 seconds. Per second billing is available for Amazon Linux and Windows instances across all Regions and AZs. It is applicable across all AWS EC2 pricing models.
