Tetra Hub

Tetra Hub is the on-premises software component of the Tetra Data Platform (TDP). It facilitates secure data transfer to the Tetra Scientific Data Cloud through components called Connectors. A single Tetra Hub can have many Connectors. Each Connector pulls or receives data from a single data source.

To set up a Tetra Hub, you must first create one in the TDP user interface. Then, download the preconfigured installer and install the Tetra Hub on a local machine or a virtual machine (VM) on your network. After installation, the Tetra Hub automatically activates and connects to the TDP. You can then configure the Tetra Hub’s data connectors through the TDP user interface based on your organization’s requirements.

Tetra Hub Versions

There are two Tetra Hub versions: Hub v2 and Hub v1 (previously Tetra Data Hub). Tetra Hub v1 is on a deprecation track.
