DP Platform terminology
Following is a set of terms that are relevant to understanding DataPlane.
- DP Platform or Platform
- The core platform that runs one or more DP Apps.
- DP Apps
- The set of apps that are available with DataPlane. These apps runs on the platform
               host, and in some cases (depending on the app) have a corresponding agent that also
               needs to be installed in-cluster. Each app also has a set of cluster requirements to
               support the app features.Example: Data Lifecycle Manager (DLM) or Data Steward Studio (DSS) 
- agent
- The agent that runs in cluster in support of a DP App.Example: DLM Engine (used with the DLM App) 
- cluster
- A Hortonworks Data Platform or Hortonworks DataFlow cluster that is registered with
               a DP instance, and then used with an app.This cluster can be running on-premise in your data center or in a cloud environment 
- DP instance
- A deployment of a DataPlane instance. This is where the platform and the apps run, usually on a single host as Docker containers.
- Apache Knox
- Provides a single-point access point for authentication and proxy of services. Knox is used under-the-hood in your DP instance to handle authentication to DP. Knox is also used in your clusters to handle Single Sign-On (SSO) and (in some cases) act as a cluster API proxy gateway.
- LDAP
- LDAP or Active Directory (AD) is used at the authentication source for DP and your clusters.
