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 application. 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 empowers it.
Cloud computing, also on-demand computing, is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers.
