Introduction

Welcome to the EKS Best Practices Guides. The primary goal of this project is to offer a set of best practices for day 2 operations for Amazon EKS. We elected to publish this guidance to GitHub so we could iterate quickly, provide timely and effective recommendations for variety of concerns, and easily incorporate suggestions from the broader community.

We currently have published guides for the following topics:

• Best Practices for Security
• Best Practices for Reliability
• Best Practices for Cluster Autoscaling: karpenter, cluster-autoscaler
• Best Practices for Running Windows Containers
• Best Practices for Networking
• Best Practices for Scalability
• Best Practices for Cluster Upgrades
• Best Practices for Cost Optimization

We also open sourced a Python based CLI (Command Line Interface) called hardeneks to check some of the recommendations from this guide.

In the future we will be publishing best practices guidance for performance, cost optimization, and operational excellence.
