From Shared Cpanel to VPS Droplet - to host multiple separate Wordpress sites
I maintain two multisite installations on two differrent shared hosting accounts, on cpanel. I'm evaluating possibility of using a droplet (VPS) for my use. My questions can sound naive but since I have no prior experience of VPS, I wish to ask :
(1) For a newbie like me, how much of a climb is a VPS setup and its maintenance to run multiple separate Wordpress sites (not multisite).
(2)Would my separate Wordpress sites on a VPS need separate installs of - (a)Wordpress, (b) Themes, and (c) plugins OR all that can be installed at one place (say root of VPS ?) where all of it could be maintained and regularly updated for use for diferent sites under the VPS.
Thanks for your answers in advance.
