Answer: Managed instance groups
The correct recommendation is **Managed instance groups**, as they provide a scalable and automated way to manage Compute Engine instances based on a predefined template. Unlike unmanaged instance groups, managed instance groups support autoscaling, which is crucial for adjusting resources based on CPU load. Kubernetes clusters and Cloud Run are designed for containerized applications, not virtual machines, making them unsuitable for this scenario. For more details, refer to [Google Cloud's documentation on instance groups](https://cloud.google.com/compute/docs/instance-groups).
