I am considering a Single Machine deployment of ArcGIS Enterprise base deployment with Imagery Server on a single machine for a small to mid sized public water & sewer authority. Current projections call for about 25 users roughly half and half viewers/editors. I had originally allotted capacity for a single ArcGIS Server machine and second machine to run my SDE GDB. Since these are both VMs I am hoping to consolidate the resources into a single machine and deploy all the components on it. If this isn't possible I will need to request additional resources from IT.
My first questions is single machine deployment feasible?
Second question is can I scale out by adding hardware at a later date or am I married to a single machine deployment?
