How many sites can I host?
I have setup a LEMP stack and intend to consolidate all of my 4-5 sites from other hosting providers to my VPS. All but one use Wordpress and they mostly serve text and a few pictures, no audio, no video. Daily traffic probably does not exceed 500 unique visitors who spend a couple of minutes browsing the pages on an average day.
Given the above parameters, is it reasonable to host this many sites on a single VPS? Are there any rules of thumb so I can avoid clogging it up with traffic?
