It feels like a huge hassle for a small business. Use a cloud, it's not that expensive. If, not even using a cloud is an option, you can still mount NFS, use a bridged network and use DHCP from that router, and run your software in systemd/upstart or simple Docker containers.

I don't like to sound like a grumpy old man that yells at new tech, I'm all good for experimentation home setups involving these, but every component you add is another thing to manage and monitor, even if you are a small business, you are still a business that you can spend your time on better things and sleep better at night.
