I creating a new SP2013 farm, with 3 servers. A database, a CA and a WFE.
The CA server will only host CentralAdmin, when the WFE will host my differents web apps.
I guess I understand that if I create a new web application, it will be hosted on both SP servers (CA + WFE) because they are part of my farm, right ?
If so, is there a way to "detach" the web app to be only hosted by the WFE server ?
Else I don't really understand the need to install a three-tier farm ...
And by the way, do you recommend me to separate intranet web app from extranet one ? So should I install the intranet web app with the CA and the extranet alone in my WFE ?
Or installing CA alone and web app (nvm intra/extra) on another side is the best practises ?
