Separate the Application Plane and the Administration Plane
For security purposes, it is often useful to separate access to services into different planes:
Application plane - used by standard users to access the different application servers through the internal load balancer.
Administration plane - used by MarkLogic administrators and allows access to each individual MarkLogic node.
This is implemented by using different Ingresses and using a custom configuration file for the HAProxy (internal load balancer).
