CloudCons: A Comprehensive End-to-End Benchmark for Cloud Resource Consolidation

2026-06-11 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Cloud Computing & IT Infrastructure · Depth: Expert, quick

Summary

CloudCons, a new comprehensive end-to-end benchmark, has been introduced to evaluate forecasting models specifically for cloud resource consolidation. This benchmark addresses the persistent issue of low resource utilization in cloud data centers, often caused by conservative over-provisioning. While emerging time series foundation models promise enhanced optimization through zero-shot generalization, existing benchmarks primarily focus on prediction error, leaving their practical decision utility unverified. CloudCons utilizes high-quality datasets from Huawei Cloud, Microsoft Azure, and Google Borg, capturing diverse workload characteristics. Extensive evaluations of statistical, deep learning, and foundation models reveal that foundation models' superior zero-shot forecasting accuracy does not inherently translate into better decision utility. The benchmark also systematically analyzes the critical role of predictive quantile selection, offering guidelines to balance resource efficiency and service reliability in real-world deployments.

Key takeaway

For Machine Learning Engineers deploying forecasting models for cloud resource consolidation, recognize that superior zero-shot forecasting accuracy does not automatically translate to better decision utility. You should prioritize evaluating models using end-to-end benchmarks like CloudCons that measure actual decision outcomes, not just prediction error. Critically, calibrate your predictive quantile selections to achieve the desired balance between resource efficiency and service reliability for your specific workload.
