Web Adaptors: one web server, two web adaptors pointing to two different AGS server sites?

MKF62 — Mon, 04 Dec 2023 17:21:56 GMT

I'm trying to figure out if this is possible, and if so, is it advisable or is it better to have two separate web servers, one for dev and one for prod? I've been reading Install Multiple ArcGIS Web Adaptors and it sounds like one website can have multiple web adaptors, but the thing that isn't clear to me is that if each web adaptor can be pointing to different server sites or can multiple web adaptors only be used if all those web adaptors are pointing to the same server site? This is what I am thinking of doing, but can't figure out if it's possible (and advisable):

The recommendation is to always have a separate webserver for development and for production.

This way you will have 2 URLs.

www.domain-dev.com (development) and www.domain.com (production).

This makes things easier, especially when you need to make changes in the development webserver to test the changes first before you apply the same changes in the production webserver.

I hope this helps.

Hi @MKF62 . We run nginx in front of our Esri web adaptors. It provides a lot of flexibility.

I suggest adding nginx or another simple reverse web proxy for your use case. A single nginx proxy will be able to route traffic to your two web adaptors, based upon the "dev" and "prod" paths, as you show in your diagram.

( from my point of view, your arrows are backwards, since IMO such arrows should reflect the direction in which traffic moves )

I 100% totally agree with MarceloMarques. It is best to have them on separate web servers. but technically yes, you can install a web adaptor called dev and configure it to use your dev ArcGIS Server instance. A second web adaptor with a different name could point to your prod Server.

My advice here is that just because you can do something, doesn't mean you should. :--)
