How to rapidly scale your application with ALB on EKS (without losing traffic)

To meet user demand, dynamic HTTP-based applications require constant scaling of Kubernetes pods. For applications exposed through Kubernetes ingress objects, the AWS Application Load Balancer (ALB) distributes incoming traffic automatically across the newly scaled replicas. When Kubernetes applications scale down due to a decline in demand, certain situations will result in brief interruptions for end […]

GitOps-driven, multi-Region deployment and failover using EKS and Route 53 Application Recovery Controller

One of the key benefits of the AWS Cloud is it allows customers to go global in minutes, easily deploying an application in multiple Regions around the world with just a few clicks. This means you can provide lower latency and a better experience for your customers at minimal cost while targeting higher availability service-level […]

Eliminate Kubernetes node scaling lag with pod priority and over-provisioning

Introduction In Kubernetes, the Data Plane consists of two layers of scaling: a pod layer and a worker node layer. The pods can be autoscaled using Horizontal Pod Autoscaler (HPA) or Vertical Pod Autoscaler. Nodes can be autoscaled using Cluster Autoscaler (CA) or Karpenter. If worker nodes are running at full capacity and new pods […]

Authenticate to Amazon EKS using Google Workspace

Introduction Amazon Elastic Kubernetes Service (Amazon EKS) makes it easy to deploy, manage, and scale containerized applications using Kubernetes. It has native support for AWS Identity and Access Management (AWS IAM) users and roles as entities that can authenticate against a cluster. Many of our customers use enterprise identity providers (IdP) like Active Directory, OKTA, […]

Blue/Green or Canary Amazon EKS clusters migration for stateless ArgoCD workloads

Introduction Organizations use modern application development approaches, such as microservices, to increase innovation, performance, security, and reliability. However, when working with legacy deployment systems, it can be difficult to maintain a fast deployment pace while maintaining control and security over each deployment. As a result, customers often turn to orchestration systems like Amazon Elastic Container […]

Deploy geo-distributed Amazon EKS clusters on AWS Wavelength

Introduction In December 2019, we announced AWS Wavelength, new AWS infrastructure that allows customers to deploy workload closer to 5G-connected users and devices. Customers can now use AWS Wavelength to deploy Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon Elastic Kubernetes Service (Amazon EKS) clusters and a suite of supported partner solutions available on the […]

Amazon EKS add-ons: Advanced configuration

This post is a follow-up to our previous post, Amazon EKS add-ons preserve customer edits. Introduction In October 2022, the Amazon Elastic Kubernetes Service (Amazon EKS) add-ons team introduced the ability to preserve edits, enabling customers to safely modify the configuration of Amazon EKS add-ons by using the Kubernetes application programming interface (API). This enhancement […]

Expose Amazon EKS pods through cross-account load balancer

Introduction Amazon Elastic Kubernetes Service (Amazon EKS) is a managed container service to run and scale Kubernetes applications in the cloud or on-premises. Kubernetes Ingress is an API resource that allows you manage external or internal HTTP(S) access to Kubernetes services running in a cluster. The AWS Load Balancer Controller in Amazon EKS creates Application […]

Blue/Green Kubernetes upgrades for Amazon EKS Anywhere using Flux

Introduction Amazon EKS Anywhere (Amazon EKS-A) allows customers to run containerized workloads on customer-managed hardware. Amazon EKS-A cluster upgrades are performed in place using a rolling process (similar to Kubernetes Deployments). Upgrades can only happen one minor version at a time (e.g., version 1.20 to 1.21) and Control plane components will be upgraded before worker […]

Windows Authentication on Amazon EKS Windows pods

Per Microsoft documentation: Windows-based networks commonly use Active Directory (AD) to facilitate authentication and authorization between users, computers, and other network resources. Enterprise application developers often design their apps to be AD-integrated and run on domain-joined servers to take advantage of Integrated Windows Authentication, which makes it easy for users and other services to automatically […]
