A team with no SRE experience converts stateless ingest services on Kubernetes to autoscale, choosing CPU-based HPA over VPA because it ships with clusters, setting per-region min/max replicas and adding a detector for max-reached to alert on sizing limits. Implementing HPA against CPU metrics and conservative thresholds reduces sizing alerts by 75% reduction, cuts manual paging, and prevents runaway cloud costs while keeping downstream services stable.
