In the past I do a lot of Azure Governance workshops. One part of this workshops are the high availabilty options in Azure. This article descripe the different SLAs for VM workloads in Azure.

In this discussion many people are confused about the difference of Availability Set and Availability Zone and how this compares to the SLA. The new feature about the Proximitiy Placement Groups comes into play to make the confusing complete. This article descripes the differences between these features.
