Private Amazon EKS Clusters and Ingress Patterns In this article, we'll explore the intricacies of private Amazon EKS clusters and ingress patterns, providing practical guidance on designing resilient multi-cluster applications. TL;DR Private EKS clusters are ideal for sensitive workloads, but require careful consideration of ingress patterns. Understanding ingress patterns is crucial for cost control, as traffic within the same AZ is generally free, while cross-AZ and inter-region traffic incurs data transfer charges. We'll discuss common pitfalls to avoid when designing private EKS clusters and ingress patterns. We'll explore the importance of using the AWS Load Balancer Controller and Application Load Balancer ingress for your EKS applications. We'll provide a checklist for setting up private EKS clusters and ingress patterns. Designing Resilient Multi-Cluster Applications When designing resilient multi-cluster applications, it's essentia...

Applying SRE Error Budgets to Services Running on EKS In this article, we'll delve into the world of SRE error budgets and provide practical guidance on how to apply them to services running on Amazon EKS. TL;DR SRE error budgets are a way to measure and manage the risk of errors in a system. They help teams prioritize and allocate resources to mitigate errors. We'll cover the key concepts and provide a step-by-step guide to implementing error budgets on EKS. What are SRE Error Budgets? SRE (Site Reliability Engineering) error budgets are a way to measure and manage the risk of errors in a system. They help teams prioritize and allocate resources to mitigate errors, ensuring that the system remains reliable and available to users. In essence, error budgets are a way to quantify the acceptable level of errors in a system, allowing teams to make informed decisions about resource allocation and risk management. Why are Error Budgets Important? Error budgets are cr...

Chaos Engineering and Resilience Testing on Amazon EKS In this article, we'll explore how to implement chaos engineering and resilience testing on Amazon Elastic Kubernetes Service (EKS). We'll cover the basics of chaos engineering, how to set up a chaos mesh, and provide a step-by-step guide on how to run a chaos experiment on EKS. TL;DR Chaos engineering is a discipline that helps you build resilient systems by introducing failures in a controlled environment. We'll use Chaos Mesh, an open-source cloud-native chaos engineering platform, to set up a chaos mesh on EKS. We'll run a chaos experiment on EKS to test the resilience of our system. By the end of this article, you'll have a basic understanding of chaos engineering and how to implement it on EKS. What is Chaos Engineering? Chaos engineering is a discipline that helps you build resilient systems by introducing failures in a controlled environment. The goal of chaos engineering is to identi...
