Azure Global Infrastructure
Similar to AWS, an Azure global infrastructure consists of regions, Availability Zones (AZs), and edge locations. At the time of writing, Azure has 60+ regions and more than 200+ physical datacenters, as illustrated on the product page (https://azure.microsoft.com/en-us/global-infrastructure/):
Like AWS, Azure products are offered via regions, so we need to check service availability and pricing based on regions. We can also build redundancy into the service by building the service in multiple AZs. However, unlike AWS, not all Azure regions have AZs, and not all Azure products support them. In fact, Azure did not announce the general availability of AZs until 2018, and they are only offered in select regions.
This is something to be aware of when picking our region. I recommend picking regions with AZs such as West US 2, Central US...
