"Author Paul Murphy's 'A strategic comparison of
Windows vs. Unix' suggested that Unix is usually a smarter business
choice than Windows. The first article in this series, 'Virtual
case study: Cutting IT costs with Unix,' looked at what it took to
implement that knowledge at a manufacturing firm. In 'Saving a
small software developer with Linux ', he showed how an ISV could
save its customers money, and itself from ruin. In this
installment, we look at how an airline can increase flexibility
with a Unix-based Real-Time Airline Operating System.
Editor's note : The following scenario is that of a consultant
brought in early in the business planning cycle for a new airline.
Unlike the other articles in this series, this example does not
reflect the author's real-world consulting experience. Murphy
worked for an airline, but nothing on this scale. SafetyJet is a
wholly imaginary company constructed solely to illustrate three
outstanding Unix characteristics:
1. Massive scalability.
2. Very high reliability.
3. The ability to use maintenance-free smart displays.
