What is Linux?

     Linux is a unique computer operating system developed by Linus Torvalds and distributed under the GPL (open license). That means that it is free! Using Linux has become a viable and affordable alternative to purchasing operating systems from Microsoft, Apple, and Unix vendors.

What are the advantages of Linux?

     Although very affordable, Linux can be a challenge for average computer users to operate (mostly because of unfamiliarity) and is not yet recommended for using on the desktop. Running on the server, however, Linux has been very successful, in both very large enterprises and small businesses. In fact, our own small company network is mostly Linux systems. The webpage you are currently reading is being run on a Linux server. Some reasons that Linux has been so successful:

• Stability - Linux has proven to be more stable than Microsoft and rarely needs rebooting or reinstallation.

• Performance - Linux will often outperform other operating systems when compared on similar platforms.

• Less Demanding Hardware Requirements - You can often run Linux servers on older computers that are too slow to run Windows. For example, an old computer from the closet could be perfect to use for installing a Linux firewall for protecting your network from the internet.

• More Secure - Linux has proven to be immune to the viruses that plague Windows. It is practically unheard of for a Linux system to catch a virus.

What are the disadvantages of Linux?

     Although Linux has some great advantages (and is free!) there are some reasons to not use Linux. In the SMB (Small to Medium Business) sector, Linux is best used for standalone solutions that do not demand a lot of integration with other processes. For example, deploying a Linux E-Mail server is a popular solution. You would probably not deploy a Linux mail server, however, if your company had integrated solutions that plugged into your mail server such as a phone system that that needed to be compatible with your mail server for voicemail features you use.

     As with any other solution, a Cost-Benefit Analysis should always be performed to calculate whether a solution is right for your organization. Locke Systems can help you determine when and where Linux would be a right fit and a financial benefit to your company.
