Avalilability Zones and their absence in Azure

Question

Availability Zones are not available in all regions in Azure yet.

So, in the absence of this feature what are some HA alternatives adopted by customers ?

Answer 1

通常将内置地理冗余与您自己实施的冗余（例如，Azure SQL复制+ 2个区域中的VM）和流量管理器\\ azure前门的结合起来。

Answer 2

That's correct, not all regions have Availability Zones. For VM's, you can use Availability Sets to get pretty close to the SLA for AZ's. You should not really use multiple regions as an high-availability option if your workload is latency-sensitive. Regions should be considered for DR.
