name: Azure VMSS Zone-Redundant Configuration Not Enabled
|
|
author: princechaddha
|
|
severity: high
|
|
description: |
|
|
Ensure that all your Microsoft Azure virtual machine scale sets are using zone-redundant availability configurations instead of single-zone (zonal) configurations, to deploy and load balance virtual machines (VMs) across multiple Availability Zones (AZs) in order to protect the scale sets from datacenter-level failures.
|
|
impact: |
|
|
Using single-zone configurations can lead to potential datacenter-level outages affecting your services' availability and reliability.
|
|
remediation: |
|
|
Configure your VMSS to use zone-redundant availability configurations to ensure high availability and fault tolerance across multiple data centers.
