Managed Instance Group Autoscaling
Create an instance template and managed instance group, then reason through health checks, rolling updates, and autoscaling behavior.

Lab Overview
Get hands-on with Compute Engine managed instance groups (MIGs). Create an instance template with startup scripts, deploy a zonal MIG with two instances, configure CPU-based autoscaling with min/max bounds, and explore rolling update strategies. Every step reinforces the MIG concepts you need for the ACE exam and real-world GCP operations.
