Do i need a site for multiple arcgis server

MauricioRamirez1 — Fri, 24 Mar 2017 13:56:02 GMT

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.

The single machine site is exactly the configuration we're looking for.

Thank you very much.

Creating one site for multiple servers (cluster) also helps in load balancing among participating servers. Also it will have a common config store.
