Enhanced VPC flexibility: modify subnets and security groups in Amazon EKS
Introduction With Amazon Elastic Kubernetes Service (Amazon EKS) users can modify the configuration of the cluster before and after cluster creation without having to create a new cluster. Before provisioning the cluster, users can define specific parameters like the Kubernetes version, VPC and subnets, and logging preferences. Post-creation, they can dynamically adjust various settings, such […]
Optimize AZ traffic costs using Amazon EKS, Karpenter, and Istio
In the evolving cloud-native landscape, enterprises utilizing Amazon Elastic Kubernetes Service (Amazon EKS) often encounter challenges that hinder their pursuit of operational efficiency and cost-effectiveness. Notable among these challenges are the costs associated with Cross Availability Zone (AZ) traffic, with difficulties associated with achieving seamless scalability, hurdles in provisioning right-sized instances for nodes, and intricacies […]
Scalable and Cost-Effective Event-Driven Workloads with KEDA and Karpenter on Amazon EKS
In today’s cloud-native landscape, efficient management of event-driven workloads is essential for real-time data processing. Traditional autoscaling often falls short amidst unpredictable event volumes, leading to inefficiencies and increased costs. Amazon Elastic Kubernetes Service (EKS), which is a managed container orchestration platform and is well-suited for deploying container-based applications. By integrating Kubernetes Event-Driven Autoscaling (KEDA) […]
Run Amazon EKS on RHEL Worker Nodes with IPVS Networking
Introduction Amazon Elastic Kubernetes Services (Amazon EKS) provides excellent abstraction from managing the Kubernetes control plane and data plane nodes that are responsible for operating and managing a cluster. AWS offers managed Amazon Machine Images, or AMIs, for Amazon Linux 2, Bottlerocket, and Windows Server. Many customers have requirements, or simply prefer, to use Red […]

Deliver Namespace as a Service multi tenancy for Amazon EKS using Karpenter
Introduction Karpenter is an open-source, high-performance Kubernetes cluster autoscaler that automatically provisions new nodes in response to unschedulable pods. Customers choose Karpenter for many reasons, such as improving the efficiency and cost of running workloads in their clusters. Karpenter works by configuring a custom resource called Provisioner. This Provisioner sets constraints on the nodes that […]
On-premises egress design patterns for Amazon EKS
Introduction When adopting a Kubernetes platform, architect teams are often highly focused on INGRESS traffic patterns. Why? Kubernetes has a first-class support for in-cluster traffic flows as well as into-cluster traffic flow implemented by ClusterIP and the INGRESS constructs .The object model allows the load balancing of Kubernetes pods natively and also extends the constructs […]
Enable Private Access to the Amazon EKS Kubernetes API with AWS PrivateLink
Introduction The adoption and large-scale growth of Kubernetes in recent years has resulted in businesses deploying multiple Amazon Elastic Kubernetes Service (Amazon EKS) clusters to support their growing number of microservice based applications. The Amazon EKS clusters are usually deployed in separate Amazon Virtual Private Clouds (Amazon VPCs) and often in separate AWS accounts. A […]
Securing API endpoints using Amazon API Gateway and Amazon VPC Lattice
Introduction In microservices architectures, teams often build and manage internal applications that they expose as private API endpoints and publicly expose those endpoints through a centralized API gateway where security protections are centrally managed. These API endpoints allow both internal and external users to leverage the functionality of those applications. The separation of concerns between […]
