Until today i was working with Controller-Model (CodeIgniter for example) or Controller-Service-Gateway (Symfony2 components) logic, but now when i am trying to learn Laravel, i've noticed what in beginner tutorials we use only Controller + Eloquent model, so at this moment i have a question, is it really what all logic in Laravel is processed in Controller, or i must find another tutorials.

For example by my "old" logic here i want to get all Articles not in controller, but in service/model, and then return edited array back to controller, and then pass it to a view.

In short: Controllers passes to a View data returned by Service, and in Laravel i don't see any services

<?php namespace Testous\Http\Controllers;

    use Testous\Models\Articles;

    class WelcomeController extends Controller {


    public function __construct()
    {
    }

    public function index()
    {
        dd(Articles::all());
    	return view('app');
    }

}
