Setting up everything for the Orchestrator Installation

Hi there,

We want to achieve the following:
Beeing able to develop remotely on UiPath Studio for Robots that will run on a server which runs Windows 10. Two People will be developing at the same time.
Use an Orchestrator on premise and connect it to 5 Unattentend Robots.
So in my understanding we need to set up:
One Server for the Orchestrator
One Server for the Processes?
One Server for each Studio Instance
5 Servers for 5 Robots?
Do we need another Server for the SQL Database?

Thanks you!
