How do I install Image Server 10.5.1 on the same machine as ArcGIS Server?
Hi Amy Brassieur I hope I am not hijacking your thread too much. I think this falls in line and may be helpful in answering your questions more. We are at about the same stage as you are....updating from AGS 10.2.x in our case but moving to a virtual server (in a remote city, vs local) and upgrading SQL, IIS etc. Unlike before when I had admin rights however, I'm at the mercy of others so not able to test as much. Such is the future. 
(sigh)
Hi Derek Law,
I would have to say that the help for installing the Image Server (or any of the "roles") is impossible to find in the help. Your link above helped me track down what I think we needed to get started (we are just getting ready to upgrade from 10.2.x).
Based on the What is ArcGIS Enterprise?—Documentation | ArcGIS Enterprise it does sound like you can put is all on one machine, assuming you have the resources (underline added):
Multiple server license roles can be applied to the same machine or site as the base ArcGIS Enterprise deployment, or they can be deployed independently of the base deployment. To ensure enough machine resources will be available to support server operations, review the system requirements for each server licensing role before configuring a multirole server or server site. It is generally recommended to deploy separate sites for each role.
So, it says you can put in on one machine OR spread it out, but the info on separating is lacking. But, I take it, assuming your server is capable (and you don't mind Image Server caching eating up the resources your have) and assuming you are licensed for the Image Server "role", you could install on one machine, you would just need to authorize it. correct? In, our case, for development purposes...although we do plan to separate. We will doing all the heavy lifting with cache creation on the dev setup...then copy/deploy to a production server for cached and dynamic/function image server. (lots to try with the new version)
There really isn't any clear info about how to "install" Image Server or and of the "additional server deployment" roles (ArcGIS Image Server, ArcGIS GeoEvent Server, ArcGIS GeoAnalytics Server, and Business Analyst Server are additional licensing roles for ArcGIS Server. ) There are links to:
- Base ArcGIS Enterprise deployment—Documentation | ArcGIS Enterprise
- About adding an ArcGIS Server machine to a site—ArcGIS Server Administration (Windows) | ArcGIS Ente... and
- Additional server deployment—Documentation | ArcGIS Enterprise
but I still haven't figured out whether a second server with a role like Image Server is considered an additional ArcGIS Server machine that must be added like you would to create a cluster, or if it is a standalone machine?
Whether is is installed on one machine or multiple, the installation of the software "role" is very confusing.
BTW - Although we have a production license, due to dev license cost, we will only have the dev license thru Aug 2018, so we need to get this all up and running soon, and get all setup, cached, and deployed, etc. Then we will only have a production license.
Thanks for you time
Hi Rebecca,
> Is federation mandatory only if having the Image Server on a second machine? Or, do we just have two ArcGIS Server installs...not connected.
Federating the Image Server site with Portal is not mandatory, but it will depend on what you want to do with the site. You will need to federate the site if you want it to be your raster analysis server and/or if you want image layers to automatically show up as items in Portal. Otherwise, you don't need to federate the site.
FYI, some background info: Perform raster analysis—Documentation | ArcGIS Enterprise
> Do you have a link to help that can explain all this better?
The ArcGIS Enterprise Dev team is working on enhancing the documentation to address this topic. However, I've attached some info in the figure below.
Regarding your specific deployment scenario, I recommend you contact your local Esri account manager and they can connect you with Esri professional services to help in evaluating your deployment criteria.
Hope this helps,
