Chapter 1 Mac OS X Server in Action 19
Small and Medium Businesses
Small businesses (fewer than 100 employees) and medium businesses (about 100 to
500 employees) benefit from cross-platform file and printer sharing and numerous
other services, including network, mail, web, and collaboration.
The following picture depicts a business with two small networks, joined by a VPN
connection. Referred to as “site-to-site VPN,” this kind of secure connection is easy to
establish when needed, as when a business needs to open another office. It offers the
additional advantage of making both networks appear as one to employees working at
either site. Using VPN service also lets employees access the company intranet to use
mail, file and other services when away from the office.
