UiPath Robots hosted as Virtual Machines

We have the UiPath Robots as Virtual Machines , Since there is a risk of manintaining the Virtual machines on high resillence , Could anyone help me in understanding how this is managed else where ?
Does these Robot VM’s are clustered seperately and maintained carefully ?
Any lead on this would be much appreciated

Hi @aarthivellingiri,
Just for better understanding I would like to ask you about potential concerns you have? Eventually if you could describe more.
