Every time I write about the energy cost of always-on infrastructure, the response lands in the same place: “Okay, so which tool should we install?”

Implementing Green Cloud Systems: A Practical Guide to Change

Thu, 19 Mar 2026 00:00:00 +0000

I will be honest about something uncomfortable before diving into infrastructure patterns.

As I write this, multiple active conflicts around the world are releasing carbon and doing pollution at a scale that makes any discussion of saving the climate/environment feel almost irrelevant. A sustained military operations can emits more carbon dioxide in a single week than all the data centers combined in a year. Environmental and climate damages by Wars takes decades to recover and Advocating for green cloud systems in that context can feel naive, or even morally hollow.

Quiet, Always-On: How Development and Test Clusters Accumulate Energy Use

Thu, 12 Feb 2026 00:00:00 +0000

Production cluster systems are the most important since they serve customers. Most of the production clusters are overprovisioned with a “just in case” reason. However, their energy use is visible, accepted, and often defended as necessary. But, not all the Kubernetes clusters are production clusters.

Kubernetes Disaster Recovery: Lessons from Natural Disasters

Fri, 25 Jul 2025 00:00:00 +0530

Introduction

Living in Japan for several years as a climate scientist taught me profound lessons about resilience—not just in natural systems, but in how we design and operate technology infrastructure. When you’ve experienced a 6.7 earthquake, felt the ground shake for almost minute, and watched earthquake warnings scroll across every screen, you gain a visceral understanding of what “disaster recovery” really means.

How to Set Up Kafka on Kubernetes

Introduction

Apache Kafka is a powerful distributed event streaming platform. Running Kafka on Kubernetes allows you to leverage container orchestration for scalability and resilience. This article walks you through setting up Kafka on a local Kubernetes cluster using Minikube, with all the necessary tools and configuration manifests.

Getting Started with CSI on Azure Kubernetes Service

Mon, 07 Jul 2025 00:00:00 +0530

Introduction

The Container Storage Interface (CSI) is now the industry standard for connecting Kubernetes clusters to a variety of storage solutions. Whether you’re launching a new workload or modernizing an existing deployment, understanding how to leverage CSI is essential. This article provides a hands-on walkthrough for deploying the Azure Disk CSI driver on Azure Kubernetes Service (AKS), combining both conceptual background and practical steps.
