Learn about the brand new Web Services that are in Drupal 8. Core Drupal can now finally read and write entities via a RESTful web service. For example, a native mobile app or Backbone single page web app can now create/read/update/delete nodes, users, terms, etc. without going through the usual web forms. Views will soon offer a Service where you can retrieve view results via a Web Service.
Drupal is now cleanly exposed for other servers and software to interact with it. Furthermore, custom bits of Drupal can add their own Services quickly and easily
