Do i need a site for multiple arcgis server

MauricioRamirez1

I'm setting up a couple of ArcGIS servers behind an NginX Load Balancer.  I talked to ESRI, and they said the load balancer does the same as the web adaptor, so it's not required.  My question now is do I need to create one site, or can each server have it's own site?  What's the benefit of creating a site.

The documentation regarding site configurations should help clarify things.  For example, the Web Adaptor can be used as the load balancer for your site, which requires you to configure a multi-machine site using shared config-store and directories paths.  If you're concerned with redundancy and availability, you can take a look at single machine sites behind the load balancer.  There's a bit more maintenance involved this these types of architectures but they eliminate one of the single points of failure in the shared config-store.  Certain directories paths will still need to be shared to give clients consistent experiences.
