GreenOps adoption is stalled by missing data from cloud providers. SPRUCE is an open-source, scalable platform built on Apache Spark that enriches cloud usage reports with open models to quantify carbon impact, build insights, and help teams reduce both emissions and cloud spend.
The environmental impact of ICT—and cloud computing in particular—is rapidly increasing, driven largely by the rise of AI workloads. While FinOps has become a standard practice for managing cloud costs, its environmental counterpart, GreenOps, is still struggling to gain traction. A key obstacle is the lack of transparent, actionable sustainability data from cloud service providers.
In this talk, we introduce SPRUCE, a scalable open-source platform designed to implement GreenOps at scale. Built on Apache Spark and leveraging open data and models, SPRUCE processes large volumes of cloud usage data, enriching provider reports to quantify environmental impact and generate actionable insights through reports and visualisations.
Attendees will gain a practical understanding of GreenOps, the current data and tooling landscape, and how a big-data–driven approach with Apache Spark can help teams measure and reduce both cloud carbon emissions and costs.
