Drupal 8 has replaced several fundamental pieces with fresh components from Symfony2. Drupal 8 is the new standard for creating incredible digital experiences—for small businesses, global enterprises, and everything in between. Symfony 2 is a powerful framework used to build web-based applications. It cannot be used to administer a website, as it’s not a CMS. What it can do is work along with the CMS and empower it.

This particular combination is a match made in open source heaven, forming a well-balanced system for a flexible CMS. Similarly, going hand-in-hand with Symfony has made PHP a mandatory language for Drupal developers.
