Cloud on Clusters and Climate

What Energy-Aware Tools Are Actually For (And What They Are Not)

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?”

Cost Is Not Carbon: Why Cheap Systems Can Emit More

Thu, 23 Apr 2026 00:00:00 +0000

This article is for teams that have recently started implementing green cloud and are new to it. Optimizing for cost and optimizing for carbon are not the same thing. In many cases, they directly oppose each other.

Why Carbon-Aware Systems Can Cost More and Still Be the Right Choice

Thu, 23 Apr 2026 00:00:00 +0000

In the previous article, I made the case that cost and carbon are not the same thing — that cheap cloud infrastructure can emit significantly more carbon than slightly more expensive alternatives. The response I got from several readers and colleagues was some version of the same question:

Implementing Green Cloud Systems: A Practical Guide to Change

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

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.

अर्का आणि अरुणिका : हवामान अंदाज आणि संशोधनातील झेप

आकृती 1: सुपर कॉम्पुटर अर्का चे उद्घाटन. सौजन्य: इंडियन इन्स्टिटय़ूट ऑफ ट्रॉपिकल मेटिऑरॉलॉजी (IITM)

वैविध्यपूर्ण हवामान आणि चक्रीवादळ, उष्णतेच्या लाटा, अति मुसळधार पाऊस व दुष्काळ यांसारख्या नैसर्गिक आपत्तींना बळी पडणाऱ्या भारताला हवामान अंदाज तंत्रज्ञानातील प्रगतीचा लक्षणीय फायदा होतो. त्यात भर म्हणून हवामानातील बदलामुळे अशा घटनांमध्ये वाढ होत आहे. अशा वेळी, अचूक हवामान अंदाज आणि सर्वसमावेशक हवामान संशोधनाची गरज आजपेक्षा जास्त कधीच नव्हती. याच पार्श्वभूमीवर पुण्यातील पाषाण रोडच्या ‘इंडियन इन्स्टिटय़ूट ऑफ ट्रॉपिकल मेटिऑरॉलॉजी (IITM)’ येथे ‘अर्का’ नावाच्या नवीन उच्च-कार्यक्षमता संगणकीय प्रणालीचे (HPC) उदघाटन २६ सप्टेंबर २०२४ या दिवशी पृथ्वी विज्ञान मंत्रालयाने (MoES) केले.
