Several reasons, including but not limited to: 1)Scalability: UNIX systems are and continue to be the primary OS of choice for large platforms running industrial strength applications, such as customer care and billing systems for a large telecommunications company. NT, simply isn't capable of handling the load. 2)Stability: Compared to UNIX, an NT system can crash much more often for a variety of reasons, where a UNIX system will hardly ever go down short of a major hardware problem. 3)Resilience: If you install NT and UNIX side by side, you will find that the NT box will have to be rebooted, several times while the unix box while hardly ever need rebooting. Every time a major change is made, the NT box has to be rebooted. UNIX does not! Allowing for real time system modification...having a system that needs to be rebooted every time a change is made is simply not suitable for running mission critical applications which have to be available 24/7. While both are fine Operating systems, NT will most likely continue as a "small office" or "small network" operating system. Large companies with gargantuan networks, will require UNIX, primarily SUN solaris, which, at this time, is the system of choice for running web farms, web servers, and the like. |
