What is a Portal Server?
A Portal Server is a VISULOX instance responsible for:
-
handling user authentication
-
managing sessions
-
serving the administration interface
-
coordinating application access
In clustered environments, multiple Portal Servers can work together to provide:
-
high availability
-
load distribution
-
redundancy
Each Portal Server has a defined role within the cluster.
Roles
Master
The Master Portal Server is the primary node in the cluster.
It is responsible for:
-
Cluster coordination
-
configuration management
-
synchronization with other nodes
Only one Master server exists within a cluster.
Worker
A Worker Portal Server operates as a secondary node and:
-
handles user sessions
-
executes workload assigned by the Master
-
contributes to load distribution and scalability
Portal Servers Page Overview

-
Server IP address
-
External DNS name
-
Current status (Active / Inactive)
-
Cluster role (Master / Worker)
From this page, administrators can:
-
add a new Portal Server
-
review server details
