Mixed‑Tenant Architecture: From Exclusive to Shared, Boosting Utilization to 45%

The article explains how moving from exclusive, peak‑sized clusters to a mixed‑tenant architecture—leveraging time‑shifted workloads, cgroup and hardware isolation (LLC, memory bandwidth), QoS tiers, elastic throttling and dynamic over‑commit—can raise CPU utilization from under 20% to over 45% and cut costs by about 30%, while introducing significant operational complexity and stability risks.
