Comment by Venkatesh Konar on "Automating Linux Installation using Vagrant and VirtualBox"

Not mandatory at all! Vagrant makes your life easy by setting up multiple VMs at the same time. Vagrant gives you a single config file to set these up, enabling you to launch all of them with one command.

You can have Multi-VM Networks setup with ease.

It helps you keeping the dev and prod environments as close to each other as possible. In an ideal world, you would provision the production environment with THE SAME scripts used to provision the Vagrant VM, to avoid deployment time surprises.

Sorry for the delayed response.
