Abstract

The exponential growth of cloud computing has been a defining trend of our time, fueled by rapidly growing demands from data-intensive and machine learning workloads. Despite the end of Dennard scaling, the cloud’s energy demand grew more slowly than expected over the past decade due to the aggressive implementation of energy-efficiency optimizations. Unfortunately, there are few significant remaining optimization opportunities using traditional methods, and moving forward, the cloud’s continued exponential growth will translate into rising energy demand, which, if left unchecked, will translate to increasing carbon emissions.

In this talk, I will argue for a CarbonFirst approach to designing cloud computing systems by making carbon efficiency a first-class design metric, similar to traditional metrics of performance and reliability. I will explain how today’s systems can be made first carbon-aware by exposing energy and carbon usage information to software platforms and then made carbon-efficient by providing control over the system’s carbon usage. I will present an initial design of a system to enable such carbon awareness and management and present several application case studies on how modern cloud applications can employ these mechanisms to reduce their carbon footprint. I will end with open research challenges in the emerging field of computational decarbonization.
