Let's say that unless you are mega-provider, which trying to pack as many as possible those cheap low-resources (10 pages, 3 forms, 5 tables, 10 requests per day Rails or whatever is current buzzword) site into one piece of leased hardware the visualization is a wrong question. Just apache's virtual hosts isn't good enough anymore, customers want Rails, Nodejs, Java for their $20/mo. Virtualization for real-world production is nonsense, especially those idiotic setups like Java under Linux under VMWare under Windows (you wouldn't believe how many "professionals" are cock-sure that this kind of setup is "robust" and most stable.) Jokes aside, Docker is eating VMWare's lunch being a fresh new meme promising miracles (yeah, problem of cache trashing and context switching for I/O in a host OS will surely be solved by someone else.
