i am a newbie and am planning to host iis server for my client in azure with auto-scale functionality.

we will test modules and update once in a week in iis server, my question is how to sync the files between vms while on auto-scaling and if we can use auto-scale only for identicals vms, then please suggest me the solution for this scenario. we will start min 2 max 10 vms in auto-scale.

Regards,
