I am not sure how a VPS is different from a Dedicated server. So I will answer based on a Dedicated server. I also run Centos 5.6. 3GHz cpu, 4 gig of memory Using a 128GB SDXC for swap.
I don't know mich about the inner workings of the web POS, I use the POS with seperate computer for each station. The biggest different I do know is the Web uses the HTML, I am not sure but WebPos can not interface to POS displays and drawer. The POS use java SWT under XUI and uses the JPOS libraries to interface to the Displays and drawers, which is why only one instance can be run on one machine under one instance of ofbiz. so to use JPOS, any Gui under linux will have to support the Java runtime. Touch screen has no relationship to ofbiz. it is a function of hardware, or one c0mputer per touchscreen. the Touchsceen interfaces through the keyboard port. Postgresql work on Server with may db's capabile. OOTB ofbiz uses 2 or 3 dbs per instance. I have 5 instances of ofbiz running on a single Postgresql server. if the server is running on a Intranet, and not on the internet, then no exrra security is required. hzzg6y sent the following on 8/29/2011 10:40 AM: > Need your help on architecturing OFBIZ.
