What does Free cost?
Documentation needs to be acquired
Training for system administration and staff
Support from a third party vendor
Developmental time and effort
![Page 7: PowerPoint version](https://reader036.vdocument.in/reader036/viewer/2022070322/5590ecee1a28ab0f748b4684/html5/thumbnails/7.jpg)
Why do we use Open Source?
Cost effective
Able to determine own upgrade path
Able to use computers longer
Easy to replicate across many libraries
Reliability
More secure

Bang for the buck
The paper "Linux as a replacement for Windows 2000" is an example of an analysis comparing Red Hat Linux 7.1 to Windows 2000; in this
customer's case, using Linux instead of Windows 2000 saved $10,000. The reviewer came from a Windows background, and after performing an intensive Linux project lasting several months
determined that "you will be stunned by the bang for the buck that...open source software offers."

Cost Comparison Web Server
Microsoft: OS $1,510 (25 clients), Email Server $1,300 (10 client), RDBMS Server $2,100 C++
Development $500, Total $5,410.
Red Hat Linux $156, everything else included.

Upgrade Costs Less For Open Source
When upgrading Microsoft you will be at the mercy of their long term pricing.
Open Source upgrades are usually free and if the price does increase from one vendor there are
other vendors to turn to.
![Page 11: PowerPoint version](https://reader036.vdocument.in/reader036/viewer/2022070322/5590ecee1a28ab0f748b4684/html5/thumbnails/11.jpg)
Open Source can operate on older hardware
Open Source can run on older hardware more effeciently than other OS's resulting in lower
hardware costs.
In some cases no new hardware is purchased because "discarded' systems can be used again.
![Page 12: PowerPoint version](https://reader036.vdocument.in/reader036/viewer/2022070322/5590ecee1a28ab0f748b4684/html5/thumbnails/12.jpg)
Open Source is far cheaper to replicate
According to Nework World Fussion News, Linux is increasingly being used in healthcare, finance, banking, and retail because of its cost advantages when large number numbers of identical sites and servers are built. According to their calculations
for a 2,000 site deployment, SCO UnixWare would cost $9 million, Windows would cost $8
million, and Red Hat Linux costs $180.

Apache has better security record than Microsoft's IIS
Eweek's July 20, 2001 article examined Apache security advisories and found that the last serious
security problem was in January 1997.
Microsoft's IIS had issued 21 security bulletins from January 2000 through June 2001
