Effective autoscaling is critical for optimizing Amazon ECS cost and performance across your containerized workloads. This session explores comprehensive scaling strategies covering both at the application and compute layer. We'll examine application autoscaling techniques including target tracking policies, custom metric definitions, step scaling configurations, and predictive scaling capabilities. On the infrastructure side, you'll learn to leverage capacity providers and cluster autoscaling to dynamically manage compute resources. You'll discover how to implement scaling architectures that automatically respond to demand fluctuations while maintaining optimal resource utilization and minimizing costs across your containerized application portfolio.
