Guide To Linux
The Linux Guide Certification development model has derived strength from two things: a critical mass of enthusiastic programmers and a unified mission to overturn the current software industry. Its business opportunities are more pragmatic: servers for e-mail, Web hosting and other networking functions.
Appliance servers. Linux Guide Certification appears to be picking up the most speed in the realm of low-cost network or "appliance" server applications-a rapidly emerging market niche that, like Linux Guide Certification, owes its existence to the Internet. Unlike traditional Unix servers, which are versatile but often carry hardware and software price tags in the $ 10,000-and-up range, appliance servers tend to be cheap devices built around single tasks such as Web serving, cache serving and firewall protection.
Linux's low-cost, scalable features already make it a can't-miss solution in the realm of low-end server systems. Linux has some very enticing features, It's small. It's free. It takes a machine (a PC or low-end workstation) that the organization would have discarded five years ago and gives it a second life
Internet servers. Thanks to its open source nature, Linux Guide Certification is easier-and cheaper-to customize than proprietary systems. That makes it attractive to Internet service providers (ISPs), who need to add cheap, easily configurable systems to their server farms because the $ 20-per-month fees they charge won't cover more traditional systems. Equally key, is Linux's ability to work well with other open source tools, particularly Apache, a free Web server program. Apache runs on about 56 percent of Web servers, according to Netcraft Ltd., a British networking consultancy Server clusters. Linux Guide Certification is turning up as an innovative, competitive player in other corners of the IT marketplace as well. Amerada Hess Corp., a New York-based oil exploration company, has saved more than $ 2 million by replacing its leased IBM RS/6000 SP2 server with a cluster of 96 PCs, each running freely copied versions of Linux. The lease cost $2.5 million for three years, while the clusters and Linux cost just $400,000. Linux, at low cost to no cost for the actual operating system, can make quite a difference when you're talking about major deployment. CIOs are finding that their system folks, when asked to complete a project with little to no budget, sometimes choose Linux. This is now fueling interest in using Linux for other tasks" from Web, file and print servers to parallel computing. Large corporations are taking notice. Recent surveys by Computerworld and Information Week show a significant interest in Linux among IT managers, although most still refuse to rely on it until they are more confident of Linux's abilities and support.
