Is there any specific IT terminology between network type techs for the software that sits in between your network infrastructure (i.e. physical kit) and your ERP/line of business apps. I.e. your active directories, DNS, DHCP, file services, remote access, app servers, proxy servers, RDBMS servers/apps, citrix, print services etc.
I wasn't sure if there is any generally accepted terminology for this area of your network. meta-structure? Or what you refer to them as in your orgs?
Is infrastructure typically referred to as your physical stuff, ie hosts, enterprise storage, switches, firewalls etc.
