I know that from version 6.1, Odoo was made to be all-in-one for several reasons. And I understand that in OpenERP server tier, there're 2 layers: Web server (or Client-Web) layer that deals with HTTP requests, and OpenERP server that communicates with database. Also, I found in this documentation about OpenERP Servers Developersfor v7.0 (https://media.readthedocs.org/pdf/openerp-server/latest/openerp-server.pdf), it is clearly mentioned that the Web layer "It is a WSGI-compliant application. As such, it can be run as a stand-alone HTTP server or embedded inside OpenERP."

Does anyone know possible ways to install those 2 layers of Odoo 8 as stand-alone, in 2 connected server? I've been searching but I have no clue.

Does it mean I have to manually split the source code (like 2 different packages of source in OpenERP 6.0), or does it mean I need to install a web server in another machine and config somehow so that it can deploy openerp source code?

Thank you!
