If we configure VM's under availability sets, if the Data Center goes down. Will the VM's from my availability sets will be migrated. Just wanted to know the theory. Please suggest me.

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.
