# Install the Data Hub and Web Connector

The Data Hub is a communication channel based on Kafka technology that enables more robust communication between OpenText Professional Performance Engineering components.

If your components communicate over the web (for example, if a load generator is behind a firewall and communicates using a proxy), you need to install the Data Hub Web Connector, in addition to the Data Hub.

The Data Hub and Web Connector must be installed on Linux. They can communicate with other components running on Linux and Windows machines.

You can download the Data Hub installation package from Marketplace. The Web Connector installation package is included in the Data Hub installation package.

After you install the Data Hub and Web Connector, you configure the components to work with them. For details, see Data Hub and Web Connector setup .
