Auto Scaling

Part of the DevOps Roadmap.

Summary

Automatically adding or removing compute capacity based on demand — the cloud-native equivalent of Kubernetes' Horizontal Pod Autoscaler, but at the level of entire virtual machine instances.

How to Learn This

  • 1Explore an auto scaling group's configuration options (min/max instances, scaling triggers).
  • 2Learn why auto scaling requires a load balancer in front of it to distribute traffic to new instances.
  • 3Understand the trade-off between scaling aggressively (cost) and scaling conservatively (risk of being under-provisioned).
