Typically, when average consumers and computer users hear the term Linux, they may look confused or seem unfamiliar with the term. Linux is the computer operating system that most of the world forgets from a hands-on end user standpoint. It’s open source and, in some cases, pretty easy to use. Many of the services you use come from large companies′ client-server networks which includes devices running a Linux distribution. In most cases, the servers hosting the web applications and databases are running Linux. These critical computing components need to be configured, maintained and also have trained staff to support them. Previously I discussed whether there’s money in programming today. In comparison, I feel Linux administrators are just as vital and capable of earning great salaries.
A Linux admin can be the IT hero in more than a few ways when it comes to the back end of the company. The enterprise has caught on that servers can run the free, open-sourced operating system and only pay minimal costs per year for hardware and sometimes support. Having an outstanding Linux admin on staff can save the company even more money by reducing the cost of support per year provided by third-party Linux vendors.
Not only can you host web apps on Linux servers, but custom applications can even be developed and run for day-to-day use. Want to handle pulling reports from one of your databases? Write SQL statements to collect the data and present it in a customized report by designing the app to run in a terminal (which is free software). Then enter the program parameters and watch your data output emerge as a beautiful report.
Of course, security is important in the enterprise. You can keep all the servers housing critical data well protected with services such as Tomcat and Apache hosting it. Your Linux admin can work with the corporate network administrator to ensure firewall rules for the network are met and the configuration file of the servers properly secured.
A Linux administration can assist in lowering the overall cost for the company as long as there is an interest in running Linux terminals or servers. The reduced costs in licensing fees and support are beneficial to the bottom line making having a true Linux administrator on your staff a great investment.Tags: Security,Software,Technology
