35) What is autoscaling in GCP?

Autoscaling is a feature of managed instance groups (MIGs) in Google Cloud Platform (GCP) that allows you to automatically add or delete VM instances from a MIG based on increases or decreases in load. Autoscaling helps your applications handle the increase in traffic and reduce costs when the demand is lower. Autoscaling is controlled by an autoscaling policy that defines the scaling criteria and limits.

The policy specifies the minimum and maximum VM instances running in the MIG and the target utilisation level for each instance group. The autoscale automatically scales based on the measured load and the options you configure. Autoscaling works by adding more VMs to your MIG when there is more load (scaling out) and deleting VMs when the need for VMs is lowered (scaling in). Autoscaling works with MIGs only. Unmanaged instance groups are not supported.
