Use aligned availability sets

SYNOPSIS

Use availability sets aligned with managed disks fault domains.

DESCRIPTION

Availability sets can be configured to align with managed disk fault domains. When aligned, the fault domain for storage is co-located with compute. Aligned availability sets help prevent compute and storage from a single VM spanning multiple fault domains.

RECOMMENDATION

Consider deploying VMs with managed disks into aligned availability sets.
