Beyond Reactive Scaling - Optimizing Amazon EKS Cost and Performance

Explore advanced resource management strategies for Amazon EKS that move beyond traditional reactive autoscaling to achieve optimal cost-performance balance in this 34-minute conference presentation from AWS re:Invent 2025. Discover how reactive scaling based on utilization metrics fails to keep pace with dynamic workloads, often resulting in either wasted resources or degraded performance. Learn to implement a proactive approach using workload-aware policies that effectively distinguish between critical services and batch workloads. Master demand forecasting techniques to anticipate traffic patterns and implement pod-level Spot instance management to reduce EC2 costs by up to 70%. Understand how to design and deploy automated control systems that maintain EKS environments as efficient, reliable, and production-ready at scale. Gain practical insights into moving from reactive to predictive scaling methodologies that optimize both performance and cost simultaneously in Kubernetes environments.
