Scaling Containers and Serverless

What changes when the unit of capacity is a task, a pod, or a request: Application Auto Scaling for ECS services, the second scaling layer under EC2-backed clusters, EKS node scaling, and Lambda concurrency.

Advanced 26 minutes 5 Learning Objectives
  1. Explain what Application Auto Scaling is and which resources it scales
  2. Distinguish ECS service auto scaling from ECS cluster auto scaling and identify which one a symptom points to
  3. Interpret the CapacityProviderReservation metric and the target capacity setting
  4. Compare the EKS scaling layers: Horizontal Pod Autoscaler, Cluster Autoscaler, and Karpenter
  5. Calculate Lambda concurrency and choose between reserved and provisioned concurrency
