Here goes the requirement.
Planning to have 5 vm’s. 2 for development 1 for test and 2 for production deployment.
Question 1)
Do I really need to have robot licence for dev vm’s?
Question 2)
Robot licence can be shared between test and prod?
Question 3)
purchasing one developer licence is enough? so that I can install studio on a VM and enable 2+ developer to use the same licensed studio by login there own profile at same time?
Is it possible?
Question 4)
Do test and prod can share the same orchestrator licence?
You will need a Studio license for development purposes. The Robot on the development machine will take Studio license because it’s for development purposes.
What do you mean by shared? Same license? Sales team would know this answer for sure.
No, in your scenario, just one license is not enough for development purposes.
Again, what do you mean by this? To have only one Orchestrator for dev/test and production? Technically you can do this but it depends a lot on your environment, on developers permissions etc. And again, sales should know these answers based on the setup you want to have.
