Only one SFTP Server for one Azure Resource group possible?

Question

Is it only possible to create one on-demand SFPT Server with one Resource group in Azure?

This is a link regards to SFPT on Azure. https://learn.microsoft.com/en-us/samples/azure-samples/sftp-creation-template/sftp-on-azure/

I tried to create a second SFPT in the same Resource group, but previous SFPT got replaced with the new one.

I tried Goolging on this one, but I was not able to find the answer, so I am posting this question here.

Answer 1

Yes we can deploy multiple SFTP server to our Azure resource group.

But the template you are using already they have declare default variables ,Instead of that we need to declare parameters as shown in below template, So that you can use the same template multiple times.
