Ionic Deploy is one of the Ionic.io services. Ionic Deploy lets you deploy the new changes to your app without submitting the app to App stores. This saves a lot of time for the developers to push new changes to their users.
Note
Changes that do not need a binary update can only be pushed—for example, assets such as HTML, CSS, JavaScript, and images.
As of today, Ionic Deploy is in Alpha.
