A VPN is a private network that connects more than one users and/or sites such as systems, servers, data servers, storage servers to one another. VPN is an alternative to directly connecting more than one systems or users with a physical line. Using a physical line may be expensive, since the line is leased and the cost may depend on the distance between each remote location.
