Application Networking with Amazon VPC Lattice and Amazon EKS

Introduction AWS customers building cloud-native applications or modernizing applications using microservices architecture can adopt Amazon Elastic Kubernetes Service (Amazon EKS) to accelerate innovation and time to market while lowering their total cost of ownership. Many customers operate multiple Amazon EKS clusters to provide better tenant isolation and to meet organizational requirements. Often, there’s a need […]

Domainless Windows Authentication for Amazon EKS Windows pods

Introduction .NET Developers commonly design Windows-based applications with Active Directory (AD) integration running on domain-joined servers to facilitate authentication and authorization between services and users. Since containers cannot be domain-joined, running these applications in a Windows-based containers required configuring group Managed Service Accounts (gMSA), domain-joined Kubernetes Windows nodes, webhooks and cluster roles to enable Windows […]

Managing etcd database size on Amazon EKS clusters

Note: etcd_db_total_size_in_bytes or apiserver_storage_db_total_size_in_bytes has been renamed to apiserver_storage_size_bytes since EKS v1.28. Please use the corresponding metric to monitor database size. Introduction Amazon Elastic Kubernetes Service (Amazon EKS) makes it easy to deploy, manage, and scale containerized applications using Kubernetes. Kubernetes clusters use etcd, a consistent and highly available key value store, as the backing […]

Fully private local clusters for Amazon EKS on AWS Outposts powered by VPC Endpoints

Introduction Recently, Amazon Elastic Kubernetes Service (Amazon EKS) added support for local clusters on AWS Outposts racks. In a nutshell, this deployment option allows our customers to run the entire Kubernetes cluster (i.e., control plane and worker nodes) on AWS Outposts racks. The rationale behind this deployment option is often described as static stability. In […]

A deeper look at Ingress Sharing and Target Group Binding in AWS Load Balancer Controller

Introduction AWS Load Balancer Controller is a Kubernetes controller that integrates Application Load Balancers (ALB) and Network Load Balancers (NLB) with Kubernetes workloads. It allows you to configure and manage load balancers using Kubernetes Application Programming Interface (API). Based on our conversations with customers, we identified two AWS Load Balancer Controller features that need further […]

Changes to the Kubernetes Container Image Registry

Introduction The release of Kubernetes 1.25 was when it was first announced that the Kubernetes project would be updating its official container image registry endpoint from k8s.gcr.io to the community owned registry, registry.k8s.io. The goal was to eventually sunset the old registry over time. However, as highlighted on the official Kubernetes website, this changeover has […]

Autoscaling Amazon ECS services based on custom metrics with Application Auto Scaling

Introduction Application Auto Scaling is a web service for developers and system administrators who need a solution for automatically scaling their scalable resources for AWS services such as Amazon Elastic Container Service (Amazon ECS) services, Amazon DynamoDB tables, AWS Lambda Provisioned Concurrency, and more. Application Auto Scaling now offers support for scaling such resources using […]

Integrate AWS Transit Gateway with AWS App Runner Private Services

Introduction AWS App Runner is a fully managed service for running web applications and API servers with little to no infrastructure. It deploys your application containers in the AWS Cloud, automatically scaling and load-balancing requests. Once deployed your AWS App Runner service gets a service URL that your clients can send HTTPS requests to. In […]

Implementing a pub/sub architecture with AWS Copilot

Introduction The AWS Copilot CLI is a tool that since its launch in 2020, developers have been using to build, manage, and operate Linux and Windows containers on Amazon Elastic Container Service (Amazon ECS), AWS Fargate, and AWS App Runner. In this post, I’ll walk you through how you can use AWS Copilot CLI to […]

Migrate existing Amazon ECS services from service discovery to Amazon ECS Service Connect

At re:Invent in November 2022 we announced a new Amazon Elastic Container Service (Amazon ECS) solution for service-to-service communication called Amazon ECS Service Connect. Amazon ECS Service Connect enables easy communication between microservices and across Amazon Virtual Private Clouds (Amazon VPCs) by leveraging AWS Cloud Map namespaces and logical service names. This allows you to […]
