Conguring high availability of web UI service
When you have a single instance of web UI service and if that server goes down, then WDM cannot be managed from web UI. So a high
availability (HA) of web UI service is recommended.
You can use load balancer proxy like ARR reverse proxy where the conguration has to be done to support high availability of web UI
service.
