Linux is one of many open sources version of the Unix operating systems. It is robust, it takes very little hardware resources to run, and it is free. The popular commercial server software is quite different. It charges hefty fees on a per-user basis, it takes up a large amount of hardware resources and runs inefficiency, at best, and it is prone to frequently shutting down.
These differences have caused many large organizations to switch to Linux operating systems for their largest computer networks and servers. Among them are many branches of the United States government. The Department of Defense relies heavily on computers running this operating system to run its operational military computers, for example.
The United States Post Office runs its servers on this software. The main benefit was the cost savings for running the free software instead of paying larger per-user fees. The Federal court system has also switched to using this software.
Many commercial enterprises have switched over their servers, as well. Computer giants such as IBM and Cisco run this program on their company servers. Google has put its own engineering spin on the software and uses it for its huge database server farms. All of your purchases on Amazon are made on computers running on this program, and all of the information available on Wikepedia is kept working on this software. Panasonic also uses this software in its company-wide networks.
Where else might one find users of this program? The countries of Russia, the Philippines, Georgia, Mexico, and Cuba run their government servers and networks using this software. Schools in Germany and Switzerland run off of this program nation-wide.
Some unexpected places where this software is used is on the New York Stock Exchange. All of those financial transactions rely on this operating system. Virgin Airlines runs its planes on this server, and the Sony PlayStation incorporates this software into their products.
There are many reputable places now relying on this server software to maintain their networks. This creates an increased need for certified operators to administrate these networks. The software may be free, but it takes skilled computer operators to keep everything running properly.
Learning how to administrate Linux is a good option for those considering a career change, or upgrading their current working situation. There are many ways to get training in this field. There are college courses that offer schooling that leads to certification, and there are online training choices available.
This is one area in the computer field where opportunities are plentiful and growing. As many organizations are looking for ways to keep costs low, this free, yet reliable software is a great alternative. Consider the possibilities of receiving training in this field, today.
