Resource Overcommit Strategies in Vivo Container Platform: Static and Dynamic Approaches

Vivo’s container platform combats oversized resource requests by first applying static coefficient‑based overcommit at deployment and then using a dynamic recommender that continuously gathers usage metrics, builds exponential histograms with a half‑life sliding‑window model, and adjusts CPU (and optionally memory) requests, improving packing efficiency, reducing billing, and boosting CPU utilization by up to eight percent while maintaining HPA accuracy.
