React, Flux, GraphQL, Hack, HHVM...? All of this and more!
Web publishing platforms like WordPress and Drupal have grown to be something that are very general purpose. In theory they can be used for a lot of things, including applications for the Internet of Things.
IoT, as it's coined, is a booming technology that is on everyone's lips. Everything from fridges to cars to cows will be connected to the internet and sending and consuming data. Web Content Management Systems want a piece of this pie. With Acquia and Automattic as the commercial champions of Drupal and WordPress, they would also like to expand business to this field.
But stretching from a blogging platform to a web content management system (WCMS) is one thing, but going to challenge critical systems is another thing completely different. This is why it is not recommended to seeing a Web CMS as the first option of an IoT platform.
Or would you trust WordPress or Drupal development houses to taking care of your building's elevators? I would imagine they would have a lot of trouble with stability and so on...
