Creating a Regional Managed Instance Group with Autoscaling and Autohealing
This lab focuses on building resilient and scalable compute infrastructure using Google Compute Engine managed instance groups in a production-like environment. An instance template is created to standardize virtual machine configuration and startup behavior, then used to deploy a regional managed instance group. Health checks and autohealing capabilities are implemented to automatically replace unhealthy instances, while CPU-based autoscaling policies dynamically adjust capacity during workload spikes. Learners then generate load and observe the infrastructure automatically scaling to meet demand.
