I guess the biggest question on my mind after reading this thread is, "Is Utility Network support on the roadmap for inclusion in the Kubernetes deployment of ArcGIS Enterprise? " I have been scouring the roadmap sessions and either I missed this, or no one is mentioning this.
I know there is also discussion in this thread that there may be a performance penalty for deploying a Utility Network ArcGIS server instance federated to a Kubernetes deployment of ArcGIS Enterprise 11.x. But what I can't seem to find any information on is the success or lack there of, of federating a multi server site including load balancing of UN Server instances to the Kubernetes deployment.
We would like to consider an option of moving to 11.1 Kubernetes deployment with federated UN Server Site and user managed SQL database (in cloud or on prem) with the idea that by the time or not too long there after the time that we get the system deployed and into production, maybe UN support in Kubernetes will be close or at least on the horizon.
