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, on a single host as Docker containers.
- Apache Knox
- Provides a single-point access for authentication and proxy of cluster services. Knox is used between your DP Instance and your cluster to handle user authentication (via Single Sign-On or Trusted Proxy setup) and (in some cases) acts as a cluster gateway proxy.
- LDAP
- LDAP or Active Directory (AD) is used as the authentication source for DP and your clusters.
