Beyond the Default Scheduler: What PhD Research Taught Us About k8s Reliability with ML Prediction and Heuristics on GCP

Camilla Martins
Senior Site Reliability Engineer
Abstract

Reliability is not just about incident response—it starts with how workloads are placed and provisioned before failures even occur. This session breaks down the journey of translating academic doctoral research into hands-on testing inside Google Cloud infrastructure. We explore how heuristic models and predictive optimization can improve Kubernetes scheduling decisions, mitigate hot-spots, and prevent cascading node degradations. Through concrete benchmarks, test architectures, and post-experiment findings on GKE, this talk delivers actionable insights for SREs looking to optimize workload distribution, lower error budgets consumption, and balance theoretical guarantees with operational reality.
