Optimizing your Kubernetes compute costs with Karpenter consolidation

Introduction Karpenter was built to solve issues pertaining to optimal node selection in Kubernetes. Karpenter’s what-you-need-when-you-need-it model simplifies the process of managing compute resources in Kubernetes by adding compute capacity to your cluster based on a pod’s requirements. With the recent release of workload consolidation, Karpenter can now be enabled to continuously monitor and optimize […]

EKS Persistent Volumes for Instance Store

The Kubernetes project is made up of a number of special interest groups (SIGs) that focus on a particular part of the Kubernetes ecosystem. The Storage SIG is focused on different types of storage (block and file) and ensuring that storage is available to containers when they are scheduled. One of the subprojects of the Storage […]

Transparent encryption of node to node traffic on Amazon EKS using WireGuard and Cilium

Introduction As the move to cloud native architectures continues to accelerate, one of the common challenges we hear from our customers is that adopting security best practices in Kubernetes clusters can be challenging. One area in particular that has come up in conversations often is how best to encrypt data in transit. This data encryption […]

Microservices development using AWS controllers for Kubernetes (ACK) and Amazon EKS blueprints

Introduction Microservices architectures make applications easier to scale and faster to develop, which enables innovation and accelerating time-to-market for new features. For business applications with multiple clients (web, mobile, desktop, and smart devices), the application programming interface (API) Gateway microservices design pattern is helpful for adding centralized control and security. Containers and serverless are two […]

Exposing Kubernetes Applications, Part 3: Ingress-Nginx Controller

Introduction The Exposing Kubernetes Applications series focuses on ways to expose applications running in a Kubernetes cluster for external access. In Part 1, we explored Service and Ingress resource types that define two ways to control the inbound traffic in a Kubernetes cluster. We discussed handling of these resource types via Service and Ingress controllers, […]

Exposing Kubernetes Applications, Part 2: AWS Load Balancer Controller

Introduction The Exposing Kubernetes Applications series focuses on ways to expose applications running in a Kubernetes cluster for external access. In Part 1 of the series, we explored Service and Ingress resource types that define two ways to control the inbound traffic in a Kubernetes cluster. We discussed the handling of these resource types via […]

Exposing Kubernetes Applications, Part 1: Service and Ingress Resources

Introduction The Exposing Kubernetes Applications series focuses on ways to expose applications running in a Kubernetes cluster for external access. In this Part 1 of the series, we explore Service and Ingress resource types that define two ways to control the inbound traffic in a Kubernetes cluster. We discuss the handling of these resource types […]

Understanding and Cost Optimizing Amazon EKS Control Plane Logs

Amazon Elastic Kubernetes Service (Amazon EKS) is a managed container service that provides a highly available single-tenant control plane to run and scale Kubernetes applications in the cloud or on-premises. Logs are an important way to debug problems, audit cluster activities, and monitor the health of your application. Kubernetes logging can be divided into control […]

Addressing IPv4 address exhaustion in Amazon EKS clusters using private NAT gateways

Addressing IPv4 address exhaustion in Amazon EKS clusters using private NAT gateways

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 […]
