Implement AWS IAM authentication with Amazon VPC Lattice and Amazon EKS

Introduction Amazon VPC Lattice is a fully managed application networking service built directly into the AWS network infrastructure that you use to connect, secure, and monitor all of your services across multiple accounts and virtual private clouds (VPCs). With Amazon Elastic Kubernetes Service (Amazon EKS), customers can use Amazon VPC Lattice through the use of […]

Operating resilient workloads on Amazon EKS

Introduction When the margin for error is razor thin, it is best to assume that anything that can go wrong will go wrong. AWS customers are increasingly building resilient workloads that continue to operate while tolerating faults in systems. When customers build mission-critical applications on AWS, they have to make sure that every piece in […]

Optimize webSocket applications scaling with API Gateway on Amazon EKS

Introduction WebSocket is a common communication protocol used in web applications to facilitate real-time bi-directional data exchange between client and server. However, when the server has to maintain a direct connection with the client, it can limit the server’s ability to scale down when there are long-running clients. This scale down can occur when nodes […]

Analyze EKS Fargate costs using Amazon Quicksight

Introduction AWS Fargate is a serverless compute engine for running Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Elastic Container Service (Amazon ECS) workloads without managing the underlying infrastructure. AWS Fargate makes it easy to provision and scale secure, isolated, and right-sized compute capacity for containerized applications. As a result, teams are increasingly choosing AWS […]

How to upgrade Amazon EKS worker nodes with Karpenter Drift

Introduction Karpenter is an open-source cluster autoscaler that provisions right-sized nodes in response to unschedulable pods based on aggregated CPU, memory, volume requests, and other Kubernetes scheduling constraints (e.g., affinities and pod topology spread constraints), which simplifies infrastructure management. When using Cluster Autoscaler as an alternative autoscaler, all Kubernetes nodes in a node group must […]

Recent changes to the CoreDNS add-on

Introduction Amazon Elastic Kubernetes Service (Amazon EKS) add-ons were originally introduced in December 2021. At launch, they provided a mechanism for installing and managing a curated set of add-ons for Amazon EKS clusters. The add-on for CoreDNS was amongst the first add-ons we released because DNS plays such a pivotal role in Kubernetes. When advanced […]

Explore etcd Defragmentation in Amazon EKS

Introduction Amazon Elastic Kubernetes Service (Amazon EKS) has gained significant popularity as a managed Kubernetes service, providing a scalable and reliable platform for running containerized applications. Behind the scenes, Amazon EKS uses etcd, a distributed key-value store, to store cluster configuration, state, and metadata. In this post, we delve into the defragmentation functionality in etcd and discuss the […]
