A region is a localized geographic area and an availability domain is one or more data centers located within a region.
By deploying your vms across multiple hardware nodes azure ensures that if hardware or software failure happens within azure only a sub set of your virtual machines are impacted and your overall solution is safe and in working condition. Availability sets ensure that the azure virtual machines are deployed across multiple isolated hardware nodes in a cluster. A hardware failure or compute hardware maintenance that affects one fault domain does not affect instances in other fault domains.
