Amazon Elastic Kubernetes Service (EKS) has become a favorite for teams managing Kubernetes clusters. But while its flexible infrastructure is fantastic, costs can add up fast if not managed correctly. Understanding where your money goes in EKS can make a big difference in avoiding unexpected expenses.
Why does cost optimization matter so much in EKS? In the cloud, you’re paying for every minute your clusters run. Misconfigured settings, underutilized instances, or heavy data transfers can drive up costs. Proactive cost management helps you make the most of your budget without compromising performance.
This is where autonomous cloud optimization tools like Sedai come into play. By continuously monitoring your EKS cluster, these tools use AI to analyze workloads, resource usage, and traffic patterns in real time, making autonomous adjustments like scaling resources, optimizing configurations, and balancing loads based on demand. Sedai’s platform minimizes manual interventions by taking on the majority of the optimization tasks, helping you keep your environment cost-efficient without constant oversight.
In this article, we’ll explore EKS cost optimization in detail, with a particular focus on how autonomous optimization tools like Sedai can enhance cost control, without negatively impacting performance You’ll learn how these tools provide real-time, autonomous adjustments to keep your clusters running efficiently and cost-effectively—saving you time, resources, and budget in the long run.
To understand where EKS costs come from, let’s review key cost drivers. These include control plane charges, worker node expenses, data transfer fees, and storage costs. For a detailed look at each of these components, you can refer to Understanding AWS EKS Kubernetes Pricing and Costs.

Control Plane Logs: One often-overlooked cost factor is control plane logging. EKS logs for components like the API server, authenticator, controller manager, and scheduler can be enabled to monitor and troubleshoot applications. However, these logs are stored in Amazon CloudWatch, incurring both data ingestion and storage fees. Optimizing these costs includes selective log retention, setting up archival processes, and using managed services like Amazon GuardDuty for threat detection.
Tracking these costs manually can be a daunting task. With the sheer number of variables, such as scaling instances or managing cross-zone traffic, EKS workloads require constant oversight to prevent unexpected cost spikes. AWS-native tools like Cost Explorer give insights into cost trends, but they still need a considerable time investment to use effectively.
Autonomous Optimization with Sedai: Sedai simplifies this process by offering real-time monitoring and autonomous adjustments. Instead of constantly tracking each cost component yourself, Sedai’s AI-driven platform analyzes workload patterns and optimizes resource usage dynamically. For example, it can autonomously adjust control plane log retention policies or manage data transfer needs, ensuring you’re not overpaying for unused or redundant resources.
One of the best ways to optimize EKS costs is by "right-sizing" resources, meaning you match resources to workload demands. Right-sizing avoids overpaying for resources you don’t need and ensures efficient resource allocation within the cluster.
Selecting the right EC2 instance type can have a huge impact on your AWS bill. Amazon offers Cost Explorer with instance recommendations based on usage patterns, making it easier to choose instance sizes that match your needs. Lighter workloads may benefit from smaller instances, while high-performance workloads may require larger ones.
AWS provides built-in rightsizing tools to suggest optimal instance types based on your actual usage. However, Sedai’s autonomous cloud optimization platform takes this a step further by continuously adjusting instances to match real-time workload needs, reducing waste without manual input. Sedai monitors your cluster and automatically resizes instances as workloads change, ensuring that you’re never over-provisioned or under-resourced.
In Kubernetes, each pod has resource requests and limits, which define the minimum and maximum CPU and memory it will use. Setting these values accurately ensures that each pod only uses what it needs, helping to prevent resource wastage. However, setting these limits manually can lead to “slack cost,” where resources are reserved but go unused.
To combat this, tools like kube-resource-report can visualize resource usage and slack cost, making it easier to adjust requests and limits based on actual utilization. Additionally, Sedai autonomizes this process by dynamically adjusting pod resources based on real-time demand, ensuring pods have just the right amount of CPU and memory to operate efficiently without over-allocation.
By continuously resource right-sizing at the pod and instance level, you can save significantly on EKS costs, making your cluster cost-effective without compromising on performance.

Autoscaling helps EKS dynamically adjust resources based on demand, which can drastically reduce costs by preventing idle resources from sitting unused. With autoscaling, you can match capacity to real-time workload needs, ensuring that your cluster has just enough resources during peak times and scales down during off-peak periods.
The Cluster Autoscaler is a Kubernetes-native tool managed by the Kubernetes SIG Autoscaling team. It monitors unschedulable pods and nodes with low utilization, making intelligent scaling decisions based on current workloads. For EKS, the Cluster Autoscaler integrates with EC2 Auto Scaling groups to dynamically adjust the number of worker nodes, ensuring your cluster meets workload demands without excess capacity.
The Cluster Autoscaler operates by simulating node changes, deciding if nodes should be added or removed before making the adjustment. To enhance performance, consider using Node Groups with similar configurations and maintaining consistency across Auto Scaling groups. This approach helps ensure nodes are optimally used, minimizing resource waste. To keep security tight, limit the Cluster Autoscaler’s permissions to only required actions, such as updating DesiredCapacity in the Auto Scaling group.
The Horizontal Pod Autoscaler (HPA) scales the number of pod replicas based on metrics like CPU or memory usage, helping avoid overprovisioned resources and reducing costs during low-demand periods. It’s a core component in Kubernetes and works with the Kubernetes Metrics Server to monitor pod utilization. When workload demand spikes, HPA increases pod replicas to handle the load, and it scales down automatically when demand drops.
This setup ensures that each application has just the right amount of resources it needs at any given time. HPA is particularly effective for managing workloads with varying demand, like web applications, where traffic may fluctuate throughout the day. By using HPA, you avoid paying for excess resources during low-traffic times.
Scheduled autoscaling allows you to configure scaling based on predefined schedules, particularly useful for non-production or test environments. For instance, a development environment may only need resources during standard working hours. With scheduled autoscaling, you can configure your cluster to scale down outside these hours, saving on costs for resources that are not actively used.
To set up scheduled autoscaling, you can configure schedules within the Cluster Autoscaler or use Kubernetes tools like kube-downscaler, which reduces pod counts outside working hours, making it ideal for development and testing environments that don’t require 24/7 operation.
Optimizing Autoscaling with Sedai: While autoscaling is effective, configuring it correctly for complex workloads can be challenging. Sedai’s autonomous cloud optimization platform takes autoscaling further by continuously adjusting scaling parameters to optimize both cost and performance. Sedai monitors your workloads, dynamically tuning Cluster Autoscaler and HPA settings based on real-time demand and usage patterns, ensuring cost-efficiency without compromising performance. Through autonomous scaling adjustments, Sedai reduces the need for manual configuration and helps avoid unexpected cost spikes.
With the combination of Cluster Autoscaler, HPA, scheduled scaling, and Sedai’s autonomous tuning, you achieve a balanced, cost-effective, and responsive EKS cluster that efficiently meets workload demands.
Selecting the right EC2 instance type is vital when managing costs in Amazon EKS (Elastic Kubernetes Service).
