MultiSite Required For Staging / Test Site?

Hi Team,
I'm looking at migrating my existing site (from Bluehost) to AWS. One of the requirements is to introduce a staging / testing site. I was planning on using Bitnami to setup our AWS and based on this article: it looks like I need a MultiSite setup. Can you please confirm, if I want to use Cloner to manage my staging site, I'd definitely need a MultiSite setup.
