Introduction to Clustering with BeyondTrust Atlas Technology

A graphic displaying a globe.

BeyondTrust Atlas Technology is designed for large scale geographical deployments of BeyondTrust. With Atlas, you use a single BeyondTrust site across multiple B Series Appliances. Since the administration is primarily performed on a primary B Series Appliance, Atlas has minimal administration impact.

This paper describes what comprises BeyondTrust Atlas Technology, how it works at a high level, and the different deployment options for you to consider.

The BeyondTrust technology which enables B Series Appliances to be deployed in a cluster.


The collective representation of all B Series Appliances that are participating in the same BeyondTrust environment.

Primary Node

The node where a majority of the configuration takes place, such as creating users, defining public sites, configuring support teams, defining traffic nodes, etc. Essentially, everything that you would typically do in a single B Series Appliance BeyondTrust installation /login interface will be done through the designated primary node for your clustered environment.

Backup Primary Node

This node is in a configured failover relationship with the primary node. In the event of a system failure on the primary node, the backup node can take over the role as primary node.

Traffic Node

This node normally handles the bulk of session traffic for the representative console and the customer client. Both the representative console and the customer client bind to a traffic node, as well as the primary node, during a session. The traffic node that is chosen will be determined by the various configuration options.

Inter-appliance Communication Pre-shared Key

This is a password that must be set on all of the B Series Appliances participating in a cluster. This key must match between B Series Appliances in order to replicate information between them and to allow them to participate in the cluster.
