Ambari Views offer a systematic way to plug-in UI capabilities to surface custom visualization, management and monitoring features in Ambari Web. A "view" is a way of extending Ambari that allows 3rd parties to plug in new resource types along with the APIs, providers and UI to support them. In other words, a view is an application that is deployed into the Ambari container.
