Introduction Many customers use Amazon Elastic Kubernetes Service (Amazon EKS) to host their mission-critical applications. As a best practice, we ask our customers to spread their applications across multiple distinct availability zones (AZ). Because “everything fails all the time,” Werner Vogel, CTO, Amazon To achieve high availability, customers deploy Amazon EKS worker nodes (Amazon EC2 […]

Introduction The Amazon VPC Container Network Interface (CNI) plugin creates many advantages for pod networking when deployed on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. First, it lets us reuse proven, battle-tested Amazon Virtual Private Cloud (Amazon VPC) networking and security best practices for building Kubernetes clusters on AWS. This allows us to use […]

With AWS App Runner, you can quickly deploy web applications and APIs at any scale. You can start with your source code or a container image, and App Runner will fully manage all infrastructure, including servers, networking, and load balancing for your application. If you want, App Runner can also configure a deployment pipeline for […]

AWS Outposts is a fully managed service that offers the same AWS infrastructure, AWS services, APIs, and tools to virtually any data center, co-location space, or on-premises facility, in the form of a physical rack connected to the AWS global network. AWS compute, storage, database, and other services run locally on Outposts, and you can […]

The ongoing growth of the internet, particularly in the fields of mobile applications, IoT, and application modernization, has led to an industry-wide move to IPv6. With 128 bits of address space, IPv6 can provide 340 undecillion IP addresses, compared to 4.3 billion IPv4 addresses. Over the last several years, Amazon Web Services (AWS) has added […]

By Efe Selcuk and Apurup Chevuru and Michael Hausenblas You know that here at AWS we consider security as “job zero”, and in the context of the shared responsibility model we provide you with controls to take care of your part. One popular use case of service meshes is to strengthen the security posture of […]

This post was contributed by Anuj Singh, Software Development Engineer and Steven David, Enterprise Solutions Architect. In this blog post, we are going to walk through a step-by-step process on how to install and use Calico for Windows containers running on Amazon Elastic Kubernetes Service (EKS). Tigera Calico for Windows is a networking and network […]

Running Kubernetes on AWS requires an understanding of both AWS networking configuration and Kubernetes networking requirements. When you use the default Amazon Elastic Kubernetes Service (Amazon EKS) AWS CloudFormation templates to deploy your Amazon Virtual Private Cloud (Amazon VPC) and Amazon EC2 worker nodes, everything typically just works. But small issues in your configuration can result […]

When using Amazon EKS, all nodes need the ability to connect to the EKS-hosted Kubernetes cluster and to other AWS APIs such as Amazon Elastic Container Registry (ECR) or Amazon S3. Nodes can run in private or public subnets. For private subnets, this traffic typically routes through an AWS PrivateLink connection to reach endpoints within […]
