summary
Katalyst colocates CPU‑heavy online services and memory/throughput‑heavy data jobs on Kubernetes and claims deployment on 500,000+ nodes with tens of millions of cores. It moves utilization from 20% to 60% by combining QoS‑aware scheduling with service profiling, multi‑dimensional isolation (CPU, memory, I/O, network), four core classes (dedicated, shared, reclaimable, system) and real‑time container resource adjustment to prevent interference while increasing overall density.
