This document describes how to create a managed instance group (MIG) that has its VMs spread across multiple zones in a region. Spreading your application load across multiple zones protects your workload against zonal failures. If a zonal failure happens, your application can continue serving from instances running in the remaining available zones in the same region.
This type of MIG is also known as a regional MIG. For more information, see About regional MIGs.
