Use it, or lose it Recycling waste heat at the edge
summary
Leafcloud runs OpenStack control planes in a Tier‑3 core and pushes compute into dozens of water‑cooled edge “leaf” sites that dump server heat into building tap water, claiming net carbon reduction by reusing most rack heat. Deployment uses Kayobe and Kolla with a single version‑controlled repo and CI pipeline, storage stays in the core with 100–200 Gbps links, and Masakari failover moves instances when an edge fails. Tests show heat reuse is simpler and cheaper using a heat pump efficiency strategy versus complex immersion cooling.
