Hello, LinkedIn Community!
As organizations scale their cloud infrastructure, understanding and managing costs becomes increasingly complex, especially when using services like Amazon Elastic Kubernetes Service (EKS). While EKS offers a powerful platform for running containerized applications, its cost structure can be opaque, leading to challenges in cost allocation, budgeting, and forecasting.
Enter AWS Split Cost Allocation Data—a powerful feature that enables more granular visibility into your EKS costs. By leveraging this tool, you can gain deeper insights into how your resources are being utilized and where your money is going, allowing for better financial management and optimization of your cloud expenses.
In this newsletter, we’ll explore how AWS Split Cost Allocation Data can be used to enhance the cost visibility of your Amazon EKS deployments. We’ll cover the benefits of this approach, practical steps for implementation, and real-world examples of how it can lead to significant cost savings.
The Challenge of Cost Management in Amazon EKS
Amazon EKS simplifies the management and orchestration of Kubernetes clusters, but with that simplicity comes complexity in cost tracking. EKS charges not just for the clusters themselves, but also for the associated compute, storage, and networking resources. Without detailed cost visibility, it’s easy for expenses to spiral out of control, especially in large-scale deployments.
Traditionally, cost allocation in cloud environments is managed through tagging—a method where resources are labeled with metadata that indicates their purpose, ownership, or project affiliation. However, while tagging is useful, it can fall short in providing the granular visibility needed for complex Kubernetes environments, where multiple teams or applications might share the same infrastructure.
Introducing AWS Split Cost Allocation Data
AWS Split Cost Allocation Data takes cost tracking a step further by allowing you to allocate costs based on more granular factors such as usage metrics and resource consumption. This feature is particularly useful for Amazon EKS, where multiple teams might share the same cluster but require distinct cost reporting.
With AWS Split Cost Allocation Data, you can split costs at various levels:
This level of detail enables you to accurately chargeback or showback costs to different departments or teams, fostering accountability and encouraging more efficient use of resources.
Benefits of Using AWS Split Cost Allocation Data
The primary benefit of AWS Split Cost Allocation Data is improved visibility into your EKS costs. By breaking down expenses by namespace, pod, or resource type, you can see exactly where your money is going and identify areas for potential savings. This detailed view helps you avoid surprises in your AWS bill and ensures that you’re only paying for what you actually use.
With more detailed cost data, budgeting and forecasting become much easier. You can set more accurate budgets based on historical spending patterns and forecast future costs with greater confidence. This proactive approach to cost management helps you avoid overspending and stay within budget.
By attributing costs to specific teams or projects, AWS Split Cost Allocation Data promotes accountability across your organization. Teams can see the direct financial impact of their actions, which encourages more responsible usage of cloud resources. This accountability can lead to more cost-conscious behavior and ultimately reduce your overall AWS spend.

If your organization uses chargeback or showback mechanisms to allocate cloud costs internally, AWS Split Cost Allocation Data makes these processes much simpler and more accurate. Instead of relying on estimates or high-level data, you can use precise cost figures based on actual usage. This transparency helps prevent disputes and ensures that costs are fairly distributed across the organization.
Implementing AWS Split Cost Allocation Data in Amazon EKS
Implementing AWS Split Cost Allocation Data in your Amazon EKS environment involves a few key steps:
The first step is to ensure that your EKS resources are properly tagged. AWS provides a range of predefined tags that you can apply to your resources, or you can create custom tags based on your specific needs. These tags will be used to split costs in the billing reports.
Next, you’ll need to enable cost allocation in the AWS Billing Console. This allows you to see cost data broken down by the tags you’ve applied. Once enabled, you can start generating detailed cost allocation reports that show how expenses are distributed across your EKS environment.
For even more granular visibility, consider integrating Kubernetes metrics with AWS Cost and Usage Reports (CUR). Tools like Prometheus and AWS Cost Explorer can help you collect and analyze usage data from your EKS clusters, allowing you to attribute costs to specific pods, services, or namespaces.
With your cost data in hand, it’s time to analyze and optimize. Look for areas where costs are higher than expected and investigate the underlying causes. Are certain pods using more compute resources than necessary? Are there underutilized storage volumes that could be decommissioned? Use this information to make informed decisions about how to optimize your EKS environment for cost efficiency.
Optimizing EKS Costs with AWS Split Cost Allocation Data
Let’s consider a real-world example of how AWS Split Cost Allocation Data can be used to optimize EKS costs.
A large enterprise running multiple microservices on EKS was struggling to manage its cloud expenses. Each microservice was deployed in its own namespace, but because the services shared underlying infrastructure, it was difficult to attribute costs accurately. As a result, the company’s cloud bill was higher than expected, and it was challenging to pinpoint the source of the overspend.
By implementing AWS Split Cost Allocation Data, the company was able to break down costs by namespace and even by individual services within the namespaces. This visibility revealed that one particular microservice was consuming a disproportionate amount of resources, leading to higher-than-expected costs. With this information, the engineering team was able to optimize the service’s resource usage, significantly reducing the company’s overall EKS expenses.
AWS Split Cost Allocation Data is a powerful tool for improving cost visibility in Amazon EKS environments. By leveraging this feature, you can gain a deeper understanding of how your resources are being utilized, allocate costs more accurately, and optimize your cloud spending. Whether you’re managing a small development environment or a large-scale production deployment, this level of visibility is essential for keeping your AWS costs under control.
