Unified Access Gateway (UAG) is a virtual appliance that act as a gateway of Horizon and Internal resources.
UAG could be deployed not only on vSphere but on Azure and EC2 of AWS.
The latest deployment scripts is provided as a zip file on the page VMware Unified Access Gateway - My VMware.
In the zip file, we can find script named "uagdeployaz.ps1", this script is for UAG deployment on Azure.
By default, the script does not create UAG with a Managed disk nor associate with an availability set.
(While UAGs for Horizon Cloud on Azure are deployed with Managed disks and associated with availability sets by default...)
I could not find the UAG deployment script used in Horizon Cloud on Azure, so I decided to struggle with the script.
I tried adding some lines to "uagdeployaz.ps1" and to create a pair of UAG with Managed disks and associate with an availability set.
My example is below.
If you would like to try above example, please set a value of Availset under [Azure] section like as below.
#
# Availability Set name
#
AvailSet=uagvail
Hope this would help someone.
