Enterprise HPC in the Age of Cloud-Native Computing

This is an Example case study of Research Institutes - many enterprises are following suit by investing in their own on-premises infrastructure, avoiding public cloud for data sovereignty, cost control, and to prevent vendor lock-in. As organizations seek to democratize cloud capabilities, the market is shifting toward hybrid and private cloud models that blend the best of both worlds, offering flexibility, security, and significant cost benefits. National Investment in Private HPC Infrastructu

stack8s: Your First Python Serverless Function on Kubernetes: A Multi-Framework Guide (Knative, OpenFaaS, Nuclio & Fission)

General Assumptions: * You have a Kubernetes cluster running on stack8s. * The respective serverless engine (Knative, OpenFaaS, Nuclio, Fission) is installed on your cluster. * You have the CLI for the respective engine installed locally (kn, faas-cli, nuctl, fission). * We'll assume an Ingress controller (like Nginx, Traefik, or the one bundled with the serverless engine like Kourier for Knative) is set up to expose services externally. If not, you might use NodePort or LoadBalancer servic

How Kubernetes Simplifies Multi-Cloud Deployments for Modern Enterprises

Kubernetes has become a household name in the tech world, and for good reason. As an open-source container orchestration tool, it helps businesses deploy, manage, and scale applications with ease. Multi-cloud strategies, where companies use multiple cloud providers, are now a common approach for modern enterprises. They offer flexibility, improved reliability, and the ability to avoid vendor lock-in. However, managing these deployments across different platforms can quickly get complicated. That

EKS Anywhere + Control Plane on Premise (vs. Google Anthos, VMware Tanzu, Azure Arc, Platform9 & OpenShift)

In EKS Anywhere, if you have a hybrid Kubernetes deployment where worker nodes exist both on AWS EKS (in the cloud) and on-premises, the control plane and communication between nodes must be carefully managed. 1. Control Plane Management * EKS Anywhere typically runs the entire control plane on-premises, meaning that the Kubernetes API server, scheduler, controller manager, and etcd database are hosted within the on-premises infrastructure. * The worker nodes can be deployed both on AWS EKS
