Ignoring speed and performance issues, and this would be for under 20 users, what would be the best minimal topology and order for installing these five MS 2016 application servers on top of Win2012R2 OS servers, ranked in order of importance:
- [DC] A Domain Controller - Requisite
- [OWA] Office Web Apps - Very Mandatory
- [Ex] Exchange - Mandatory
- [SP] Sharepoint -Somewhat Optional
- [Sk] Skype Server - Very Optional
We'd like to use only two OS servers/instances if possible, but would there be vast improvement gains from three or four OS's running on lower-performing CPU's (where [enclosed in bracket is running on one OS] and left to right is the order of installation):
Setup1:
- [DC]+[OWA,Ex,SP,Sk]
Setup2:
- [DC]+[Ex]+[OWA,SP,Sk]
Setup3:
- [DC]+[Ex,Sk]+[OWA,SP]
This is also presuming multi-partitioned hard-drives as required by the installation, with complete instance snapshots performed weekly as backups.
