Stephan Cock, director at BisArts, explains why the company prefers
Linux from a technical point of view: “What I like about Open Groupware
is that it's open platform and can be used by Mac, Windows and Linux,”
he says. “It compares favourably in terms of price. Security-wise, what
I like is that the end-user never gets to talk to the server directly,
but uses a proxy server – Apache. It uses PostgreSQL, one of the best
database servers, and on the POP3 side, they've used Cyrus, a mail
server that will scale to thousands of users with ease.”
