Answer: Regional managed groups
An instance group is a collection of virtual machines (VM) instances that can be managed as a single entity. There are two types: Managed and Unmanaged Instance Groups. A managed instance group (MIG) that spreads its VMs across multiple zones in a region is known as a regional MIG. This approach is ideal for improving application availability by leveraging the redundancy of multiple zones within a region.
