Does each ArcGIS Server Role require its own Web Adapter?

[JonSwoveland]

I am planning an ArcGIS Enterprise 10.7.1 deployment including a GIS Server, Image Server & GeoEvent Server.  This is the first time I have deployed Image Server & GeoEvent Server, and I'm trying to figure out if each of these servers should get their own Web Adapters, like the following:

• Portal: /portal
• GIS Server: /server
• Image Server: /image
• GeoEvent Server: /geoevent

Thanks for any input!

Are you using single or multiple machines? Deployment scenarios—ArcGIS Web Adaptor (IIS) Installation Guide | ArcGIS Enterprise  

Here we have one single machine with two Webadaptor configured to Portal (/portal) and Server(/server) on Linux

Planning on a single machine to host all the web-adapters.

From what I can tell, each GIS Server role will need its own Web Adaptor, but you can configure more than one Web Adaptor all on the same machine.

Yes, each distinct federated site would need its own web adaptor.

Hi Jon,

Yes, typically you would want one Web Adaptor for Server, one Web Adaptor for Portal, and a Web Adaptor for each licensing role (Image Server, GeoEvent, etc). The reason why you would need a separate Web Adaptor for each licensing role is because these servers operate as additional ArcGIS Server sites federated with your Portal, and otherwise the end-user would have to access the sites through the port number, which is not a security best-practice. 

The way that you laid it out in your original post:

• Portal: /portal
• GIS Server: /server
• Image Server: /image
• GeoEvent Server: /geoevent

This would be perfect for this kind of deployment. You will need to install and configure each Web Adaptor separately; for example, even if Portal and GIS Server are on the same machine, you will need to run the Web Adaptor installation twice.

Hope this helps!
