You must install a Tetra Data Hub on a network server or virtual machine (VM) that is dedicated to TetraScience (for example, the server or VM must allow TetraScience to remotely reboot the machine without causing any impact). The network server or virtual machine (VM) must meet these system, user, hardware, and network requirements:
64-bit versions of these platforms are supported:
- Ubuntu 18.04 or later
- RedHat 7.5 or later
- CentOS 7 or later
You need admin (sudo) access of the machine
- 2 GHz+ processor
- 8 GB RAM required, 16GB RAM recommended
- 50 GB+ available disk space
- 4 CPUs minimum recommended
- Outbound Internet access
- Minimum 1 port should be available (Each connector should have a dedicated port)
- Minimum network bandwidth -100 Mbps network is required, but 1000 Mbps is preferred
The Tetra Data Hub uses AWS SSM Agent. The instance running the Data Hub/SSM Agent must have outbound Internet access. The outbound Internet access connects AWS services endpoints.
All communication from the SSM Agent is outbound HTTPS to the SSM, and EC2 messages endpoints in the region where your instances are registered. The SSM Agent does not require you to open any inbound ports so inbound Internet access is not required.
Each Connector installed on the same Data Hub machine uses a different port to communicate with a Tetra Agent. To install Connectors, you need to set the minimum number of available ports to 1. If you are going to use multiple Connectors but ports are limited on one Data Hub machine due to security reasons, then you need to create multiple Data Hub machines and install Data Hub on each of them.
The Tetra Data Platform (TDP) uses server-side encryption for S3.

The Data Hub requires a consistent and accurate time reference. You can use existing NTP sources or Amazon Time Sync Service.
Data Hub supports proxy settings. For details on how and when to configure proxy settings, click here.
