Microsoft has now announced its long pending Availability Zones in each region. It is currently on preview and recommended only for non-critical workload as Micorsoft does not provide any SLA now. With this, you can now provision your workload from different data centers in the same regions for resilience as you will have options to select between minimum of 3 AZs in each region with GA. However, it is now available only on East US2 and West Europe for Preview.
AWS currently operate 44 AZs across 16 Regions and 14 more AZs are already planned (44+14 =58). Microsoft currently operate in 36 regions and 6 more to come. If you assume that Microsoft will bring 3 AZs minimums at each of these regions, Microsoft would have (36+6) *3= 126 which itself is more than double the size of AZs across the globe. I agree, it does not make much sense to just play with the numbers so Microsoft need to bring the services that would help customers to make use availability zones and add value to their workloads hosted in Azure services. AWS currently offers multiple PaaS services for their Multi-AZ deployment model so Microsoft still need do good job on making sure that more services are available for Multiple AZ deployments.
