Windows NT 40 Verses Lynix

for Linux. The Linux community may point to numerous projects and small companies that are aiming to deliver High Availability functionality. D. H. Brown recently noted that these offerings remain immature and largely unproven in the demanding business world. There are no OEMs that provide uptime guarantees for Linux, unlike Windows NT where Compaq, Data General, Hewlett﷓Packard, IBM, and Unisys provide 99.9 percent system﷓level uptime guarantees for Windows NT﷓based servers. Windows 6Myth: Linux is Free Reality: Free Operating System Does Not Mean Low Total Cost of OwnershipThe Linux community will talk about the free or low﷓cost nature of Linux. It's important to understand that licensing cost is only a small part of the overall decision﷓making process for customers. The cost of the operating system is only a small percentage of the overall total cost of ownership (TCO). In general Windows NT has proven to have a lower cost of ownership than UNIX. Previous studies have shown that Windows NT has 37 percent lower TCO than UNIX. There is no reason to believe that Linux is significantly different than other versions of UNIX when it comes to TCO. The very definition of Linux as an Open Software effort means those commercial companies like Red Hat will make money by charging for services. Therefore, commercial support services for Linux will be fee﷓based and will likely be priced at a premium. These costs have to be factored into the total cost model. Linux is a UNIX﷓like operating system and is therefore complex to configure and manage (Berinato, 1999)Existing UNIX users may find the transition to Linux easier but administrators for existing Windows﷓based or Novell environments will find it more difficult to handle thecomplexity of Linux. This retraining will add significant costs to Linux deployments. Linux is a higher risk option than Windows NT. For example how many certified en...
