Drupal is used on million sites such as WhiteHouse.gov, World Economic Forum, Stanford University, Examiner.com and many more. It is considered as leading CMS in variety of industries.If you are developing a website with content management system, Drupal CMS is very flexible than any other CMS. It is PHP based template and allows non-technical users to add and edit the content without any HTML or Web design knowledge. It connects your website to other sites and services using feeds, search engine connection capabilities etc. It manages content on informational sites, social media sites, member sites, intranets and web applications.Drupal is easy to manage or create blog or website. This kind of platform cross-pollination will both stimulate further improvements in Drupal and inevitably lead to greater adoption of Drupal as both a CMS and a web-services platform. In Drupal 8, however, all configuration data is stored in YAML files. This new feature permits content updates directly on the page using AJAX instead of the traditional edit form workflow.
