Optimizing Resource Management in Amazon EKS with Namespace Resource Quotas and Pod Resource Requests & Limits

In Amazon EKS (Elastic Kubernetes Service), efficiently managing resources is crucial for maintaining performance, cost-effectiveness, and ensuring fairness across multiple teams or workloads. Kubernetes provides two key mechanisms for resource control: Namespace Resource Quotas and Pod Resource Requests and Limits.

While these mechanisms operate at different levels, they complement each other to provide comprehensive control over resource allocation in your cluster. In this blog, we’ll explore how and when to use Namespace Resource Quotas and Pod Resource Requests and Limits, provide detailed YAML configurations, and share best practices for deploying them in an EKS environment.

Why Resource Management in EKS Matters

Amazon EKS simplifies running Kubernetes clusters in the cloud, but with shared environments or multi-tenant architectures, resource mismanagement can lead to:

• Overconsumption: One team or application might consume more than its fair share of resources, leading to starvation for others.
• Unpredictability: Workloads can cause unplanned outages or performance degradation without clear resource allocation.
