If I were to add an ArcGIS Server site that was specifically for Enterprise SDE databases, which has 2 ArcGIS Server machines, would I need a Web Adaptor in-front of them before federating them to the portal site, so the Load Balancer sends the request to the Web Adaptor which round-robins between the two ArcGIS Server Machines, or would the rules be applied at the Load Balancer, rendering the Web Adaptor obsolete for SDE sourced ArcGIS Servers as well as the hosted ArcGIS Server machines?
Could we just register our SDE data sources with the hosting ArcGIS Servers already deployed in this scenario and avoid the whole need for a second ArcGIS Server site specifically for SDE data?
Also, would the standard Windows Network Load Balancer be sufficient for this scenario, or should we consider a 3rd party?
Sorry for the many questions...
Thanks!
