Scale In At Your Own Pace With Compute Engine Autoscaler Controls
In a Compute Engine environment, managed instance groups (MIGs) offer autoscaling that lets you automatically change an instance group’s capacity based on current load, so you can rightsize your environment—and your costs. Autoscaling adds more virtual machines (VMs) to a MIG when there is more load (scaling out), and deletes VMs when the need for VMs is lesser (scaling in). When load declines, the autoscaler removes all unused capacity. This allows you to save costs but might cause the autoscaler to scale in abruptly. For example, if the load goes down by 50%, the autoscaler removes ~50% of your VMs immediately after…
