my requirement is to have highly available ArcGIS Enterprise Deployment and I have machines (P1,P2, S1,S2,DS1, DS2). I want to federate ArcGIS Server with Portal, configure ArcGIS datastore and set hosting server in Portal. I am going to use AD authentiocation for this deployment.
Now, I am following steps documented here
I first create the multiple machine arcgis server site documented here highly available consideration section.
Is Multiple machine site with multiple web adaptors is also a Active-Active deployment scenario ?
I have Web Server so, For steps 4 and 6 where should I installed Web Adaptors for Portal? First Web adaptors in First web server and Second web adaptor in second web Server ? it is not documented here Configure a highly available portal—Portal for ArcGIS (10.5.x) | ArcGIS Enterprise I know that second web adaptor can only be configure with portal after setting the webContextURL property in portal admin directory.
After federate Server with Portal, Server authentication security and roles managed by Portal so, in that case Do I need Web adaptors for ArcGIS Server ? If do not required Web adaptors for ArcGIS server multiple machine site than how load balance will be handle for multiple machine site ?
How do I federate Server with portal as ArcGIS server site is multiple machine deployment ? Do I have to use NLB URL to federate the server with portal ?
Also, How do I set hosting server in portal as it is highly available deployment and we can set only 1 hosting server for Portal?
