Of the world because they are scalable, reliable, and much less expensive than mainframe Unix and Linux constitute the backbone of corporate infrastructure throughout much Used when there are more than 3,000 client computers in a network. Although Microsoft Windows Server 2003 is capable of providingД®nterprise-wide operating system and network services, it is generally not

The client level, 95 percent of PCs and 45 percent of handheld devices use market for operating systems, which manage the resourcesДЄnd activities of the computer, is expected to amount to $100 billion. A single IBM mainframe can run up toДЎ7,000 instances of Linux or Windows server software and is capable of replacing thousands Has also repurposed its mainframe systems so they can be used as giant servers for massive enterprise networks and corporate Web sites. Over the last decade, although the number of providers has dwindled to one: IBM. The mainframe market has actually grown steadily Server market for Unix and Linux machines, which might use SUN or IBM Unix Settled on Intel as the standard processor, with major exceptions in the The machines, and three chip producers, Intel, AMD, and IBM, which accountДЇor over 90 percent of the processors sold in 2004. Such as IBM, HP, Dell, and Sun Microsystems, which produce 90 percent of Server or by external mass-storage drives.ДЇor computer hardware has increasingly become concentrated in top firms Secondary storage may be provided by a hard drive in each blade They take up less space than traditional box-based Blade servers are ultrathin computersД¬onsisting of a circuit board with processors, memory, and network connections Servers in racks, but also includes Sun SPARC microprocessors and IBM PowerPCД¬hips specially designed for server use.

LetвЂ™s examine the size and dynamics of each these infrastructure With system integrators (often accounting firms), and promises to work with whicheverДatabase products its client firms wish to use (even though it sells its own database management For instance, a hardware and services provider such as IBM cooperates with all the major enterprise software providers, has strategic relationships

The vendor firms have been forced by large customers to cooperate in strategic partnerships Purchasing firms a mixture of incompatible, proprietary, partial solutions. In the past, technology vendors were often in competition with one another, offering
