In today’s rapidly advancing technological world, addressing environmental sustainability is becoming increasingly crucial, especially with the increasing energy demands of data centers. In this session, I will introduce Kepler, a CNCF Sandbox project designed to monitor and report the energy consumption of applications in the Cloud. Kepler simplifies estimating container energy consumption and provides important insights into energy efficiency, carbon footprint, and sustainability. Using Kepler, developers, and system administrators can make informed decisions to optimize the energy efficiency of their applications in Kubernetes environments. This talk will give you a clear understanding of Kepler’s architecture, its role in improving energy management, its broader software ecosystem, including current activities and project roadmap.
