Tetra Hub is the on-premises software component of the Tetra Data Platform (TDP). It facilitates secure data transfer between the TDP and Connectors and Agents, which can each pull or receive data from individual data sources. A Hub can integrate with many Connectors and Agents, allowing it to interact with many data sources.

Architecture

The following diagram shows an example Tetra Hub workflow.

For Agent connections set up through a Hub, uploads are sent by using the Hub itself as a pair of proxy servers. Connectors set up through a Hub are orchestrated by Amazon Elastic Container Service (Amazon ECS). For outbound communication to the TDP, Connectors use the Hub’s parent proxy, if there is one.

NOTE

To transfer data to the TDP securely, Tetra Hub uses AWS Systems Manager and AWS IoT. For more information, see the security considerations for Tetra Hubs.

Installation

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