Most servers are, but just because they're console doesn't mean they need to be separate virtual machines. I use separate servers for mine partly because I use a mix of T-SQL and MySQL, and the databases I have store local govt information, so it's a requirement that they not be connected to the internet.

Your separation makes more sense than mine kkkkk.
But i separate server beacause i never use the same VM for server and for development. To server i use hardering and more restrictive security rules.
To development i need less restrictive rules and use graphical interface to use programs like visual studio code, atom, sublime, mysql workbench, genmymodel, browser and other visual tools.
For development i need more flexibility and for server i need the maximum security as possible.
Sometimes I separate to avoid version compatibility errors. For example, sailsjs give some problems with the last version of node js, but i like to use the last version of node js in Ionic 3 and angular 4.

Note: Sorry for my English, it's not my native language.

That's fair. I've almost never any need for a graphical environment. Most of the code I write I'm using Vi (yes, I know I'm old school), MySQL has a very amazing command line interface (it even does text formatted tables for you!), and all of the compiler lines are command line anyways.

I do see a good point in separating out for version compatibilities though. I don't use Node (or any JS framework for that matter), because I think those things are terrible languages to begin with, and my views on anyone who tries to write desktop software using a web scripting language are very low. But whatever works for you works man.

Previously I also only used vim and nano to develop, but after that I started using c# with visual studio to create graphical interface, i too started using GUI for everything.

You who like terminal and do not like node js, try to take a look at the terminal-kit, i think that you might like this. https://www.npmjs.com/package/terminal-kit
