Advanced configuration: Setting up bridge for data virtualization

The Bridge is a connectivity hub hosted by the customer, offering outbound-only, short-lived, and highly secure connections. It is powered by Trustgrid, and trusted by banks, healthcare companies, and many other organizations with strict security and compliance needs.

While customer-hosted metadata collectors and technical lineage servers don't require inbound connectivity, data virtualization/federated query and metadata collection do. The Bridge serves as a secure method for facilitating these outbound-only connections. provides the Bridge, and it can be deployed either as a hardware appliance or a software virtual appliance with image support for AWS, vSphere, Microsoft Azure, and Google Cloud Platform.

High-level architecture takes care of the Application, Gateway Node, and Cloud Management components. The customer is only responsible for managing the Edge Nodes and establishing a connection to the Database. These are the databases, BI tools, etc., that need to connect to

We recommend a high availability (HA) implementation. Customers using the Bridge are provided with up to two nodes.


Network requirements

Should your organization have outbound internet traffic firewall settings, or in the event of a firewall between the nodes and your servers, it's important to implement necessary firewall rules that permit traffic from the Bridge. If you need assistance determining the required firewall rules, feel free to contact support.

In cases where your environment includes multiple VLANs, ensure the switch ports are configured to allow access to the correct VLAN.

For Standard (one node) setup:

  • 1 Public IP Address

  • 1 Private IP Address

  • 2 DNS Servers

For High Availability (Two Nodes) setup:

  • 2 Public IP Addresses

  • 2 Private IP Addresses

  • 1 Private IP Address for Cluster IP

  • 2 DNS Servers
