a back-end server has more to do with the objectives you are attempting to accomplish.
Back-end servers are inside the corporate firewall, and provide a platform to house mailboxes. These servers are used through storage groups and databases.
Front-end servers are on the perimeter of the network, and optimize the configuration of Exchange by offering:

- Enhanced security
- Improved public folder access and features
- Increased IMAP access to public folders
- Multiple protocol support
