Open source software has generated much interest, especially in the wake of a slow economy. One of the main reasons open source technology is being considered by more IT departments is because open source technology is perceived as being free of charge. While that perception is not all together true, this article will discuss an example of the real cost savings of open source technology as an enterprise system solution. All costs related to the implementation of an open source server operating system including the hardware costs to run the operating system software, training costs to setup the operating system software, support cost to maintain the operating system software, and staff salary to administer the operating system software will be recognized in this article. Open source refers to any program whose source code is made available for use or modification as users or other developers see fit. Open source software is usually developed as a public collaboration and made freely available Open Source , 2008 . This paper examines the enterprise level cost of an open source technology system. Different factors discussed in this paper include the cost of open source software, the cost of open source hardware, the cost of open source training to support this platform, and the salary requirements for open source administrators. For the purpose of this paper, the total cost of ownership of an open source production database server will be discussed in detail. There are many different distribution options or ‘flavors’ a technology manager can choose from that are considering an open source operating system. Linux is about freedom and choice, so one has plenty of freedom to choose the flavor of Linux that best fits the business needs Linux Distributions , n.d. This includes the cost for Hardware and software technology – client computers, servers, software, printers, networking equipment, external service providers Direct labor - those responsible for purchasing, training, implementation, management and support of the computer environment Indirect labor – time spent by users in training, dealing with computer and networking issues, and effect of computer or network down-time. With the Premium Subscription of Red Hat Enterprise Linux Advanced Platform you get the following: Server applications to include ISV applications, Apache, Samba, nfs, ftp, Tomcat, MySQL, and PostgreSQL For the purpose of this paper the server this Red Hat software will run on will be a Dell PowerEdge Energy Smart Quad Core Intel Xeon L5410 server. The skill sets required to support an open source environment requires a person who completely understands how each component in an environment works. Jay Beal 2004 provides skill sets a Linux Administrator should have would include security, operating system hardening, software installation, hardware installation, system assessment, troubleshooting, and intelligence gathering Essential Linux Skills , 2004 . Because open source software is mostly supported by the ‘community’, it can be tedious to find solutions to complex problems. Finding a good Linux administrator to administer the open source environment is hard to do. One of the benefits of having an open source environment is training courses are usually reasonably priced. The only difficulty is finding a training center that specializes in open source technology training. Below is a table that summarizes the total cost of ownership for a typical open source database environment. $1299.00 per year $100,000 per year $1500.00 per year Total Cost $102,799.00 per year $6250.00 purchase price Total One-Time Cost $6250.00 As one can see from the table above, open source technology is not free. Open source proponents and proprietary companies disagree on the total cost of ownership. Even with all this being said, the myth that open source technology is free just is not a true statement, especially in a production environment.
