Do we need different orchestrator for different environments of our project?

Hi All

Once we develop our project in the developer machine do we need different orchestrators for different environments of our project or in the same orchestrator we can create different environments with different machines/VMs ?

i would suggest you please go through orchestrator training provided.
To answer your question , you can use individual/same environments according to project requiremen. But you do not need new orch for it.
