(and not pressing ctrl-enter too soon this time -

We're commissioning Ignition in an Azure environment based on Windows VMs. We have three VMs configured to deliver the frontend app (perspective).
Load testing has been challenging, and it looks like we're going to need to increase the compute resource used - either additional servers, or scale-up.
Problem is that our user load will be very peaky, with potentially weeks between high demand sessions. This means we have VMs sitting providing capacity we don't need.
Normally I'd create a scale set in Azure to allow automatic VM scale-out. Question is whether this is going to be possible with Ignition? The servers only have a handful of modules installed (EA, Perspective, Reporting and Tag Historian), but I'm not sure whether it's going to be possible to spin up and connect servers on demand.
Any guidance welcome! Thanks!
