Configuring bridge for data virtualization

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

Customer-hosted metadata collectors and the technical lineage server do not require inbound connectivity, however data virtualization / federated query and metadata collection does. The Bridge enables a secure, outbound-only method for brokering those connections.

The Bridge is provided by, and can be implemented as a hardware appliance or a software virtual appliance (image support for AWS, vSphere, Microsoft Azure, and Google Cloud Platform).

High-level architecture handles the Application, Gateway Node, and Cloud Management aspects. Customer responsibility is only the Edge Node(s) and connection to the Database (which represents the databases, BI tools, etc. that is desired to connect to

We recommend a high availability (HA) implementation, and will provide up to 2 nodes for customers if they are using the Bridge.


Network requirements

If you firewall outbound traffic to the internet, or if there will be a firewall between the nodes and your servers, please be sure that the necessary firewall rules are in place to allow traffic from the Bridge. Please contact support with any questions regarding the necessary firewall rules.

If your environment involves multiple VLANs, prepare the desired switch ports to allow access to the correct VLAN.
