How did you scale up ArcGIS Enterprise?
We are outgrowing our current ArcGIS Enterprise set up and I am a bit hesitant on how to scale up.
Currently, we are on an ArcGIS Enterprise 11.1 single machine deployment and a separate older standalone ArcGIS Server. Also on the Utility Network. There are ~100 staff who are mainly web & mobile GIS users. GIS performance is...clunky at best. I know it can be better. Up until recently, ArcGIS enterprise administration was done by a third party contractor. So I am learning as I go.
After researching, I believe we need one VM per enterprise component (Portal, Sever, & Data Store). So that's three VMs. I've also heard our Utility Network should be on it's own enterprise deployment. So that's six VMs. I would also like a dev UN deployment. So that is total nine VMs.
To scale up to this architecture, we will likely need to purchase another server (on prem).
Before committing....I am curious how others have set up their deployments.
Edit: I was told by GIS Consultants that the UN needed it's own "Portal." I know see they were probably misusing that word and maybe meant Server. It's just funny this came from more than one consultant. Thank you for all of the feedback! As I stated before, I am still learning ArcGIS Enterprise.
