Detailed explanation-1: -Azure regions are designed to offer protection against localized disasters with availability zones and protection from regional or large geography disasters with disaster recovery, by making use of another region.
Detailed explanation-2: -Not every region has multiple Availability Zone. Some regions may have only one Availability Zone. One can run both Linux and Windows virtual machines created in the availability zone. Availability zones are used to replicate data and applications in the same region.
Detailed explanation-3: -Availability zones provide efficient multi-datacenter replication and data redundancy within a geographic region (such as a coast or a country). In this configuration, data is replicated within an availability zone’s series of datacenters.
Detailed explanation-4: -While a single availability zone can span multiple data centers, no two zones share a data center. Abstracting things further, to distribute resources evenly across the zones in a given region, Amazon independently maps zones to identifiers for each account.
