bundle

Hi,
I would like to know if all the bundles (tomcat, wildfly, deploy) are required and have to be install, in order to set up a Bonita BPM Server.
Looking at the documentation to set up a server but, unless I missed it, they don't say if all the bundles are required.

Futur application of the server : (If they require bundle then tell me)
This server will lately be used by other people
I will use LDAP for the authentification
I will have 3 users groupe, user, manager, admin
I will use report and save the stats in a DB

I don't have experience with virtual machines and servers but does the installation of the bundle requirement a VM with a GUI or are command lines enough?

Thanks in advance
