They (Azure) do for most operations.

I've found actual reboots to be rare - the exception being the recent Spectre / Meltdown patching.

I'm not sure about GCE but in Azure often the largest node size in a particular family (i.e. D15_v2, G5, M128, etc.) is isolated / dedicated to a single customer.

This part is interesting considering the performance concerns:

"The majority of Azure customers should not see a noticeable performance impact with this update. We’ve worked to optimize the CPU and disk I/O path and are not seeing noticeable performance impact after the fix has been applied. A small set of customers may experience some networking performance impact. This can be addressed by turning on Azure Accelerated Networking (Windows, Linux), which is a free capability available to all Azure customers."
