Availability Set conf
Hi
No you have to change the high availability option to availabilty zone if you want to prevent datacenter outage .
Availability set give you options to have fault domains and update domains to prevent outage due to unplanned, planned maintenance or an hardware failure inside the datacenter . Now if you want your workloads to be accessible in case of a datacenter failure you need to put your VM in an availability zone or replicate your vms using Azure Site Recovery . Availability Zones are fault-isolated locations within an Azure region, providing redundant power, cooling, and networking . So the difference is while availabilty sets are logical and scoped to a datacenter, availability zones are unique physical locations within a region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

- Suresh_GodabaMar 26, 2021Copper ContributorGot you and thank you in detailed, so the AV sets are Data Center Specific and for HA they (VM) will use FD / UD? right.
AZ's are good right for highly prod VM's to single point of failure.- ibnmbodjiMar 27, 2021Steel ContributorYes that's true
Availability sets provide redundancy accross the datacenter while availability zones provide redundancy accross regIon .
