The document compares open source software (OSS) and proprietary software. It defines OSS as software where the source code is made available under terms allowing redistribution and modification, while proprietary software is developed by commercial entities and licensed for a fee. The document then discusses some of the key points that OSS and proprietary software each promote, such as OSS being free of charge but proprietary having lower overall costs. It also covers issues around reliability, vendor lock-in, support, and total cost of ownership between the two models.

- 3. Sept 2014 Proprietary Vs. OSS Definitions Open Source is a software-licensing model where the source code of the software is typically made available royalty-free to the users of the software, under terms allowing redistribution, modification and addition, though often with certain restrictions. Commercial Software, proprietary is the model where the software developed by a commercial entity is typically licensed for a fee to a customer (either directly or through channels) in object, binary or executable code. The source code of the software may be made available1 to certain users of the software through special licensing or other agreements
- 4. Sept 2014 Proprietary Vs. OSS OSS Promotes: OSS is free of charge Source code availability leads to higher quality OSS is reliable OSS avoids vendor lock-in Support for OSS is available from commercial vendors
- 5. Sept 2014 Proprietary Vs. OSS Proprietary Promotes: Proprietary has lower overall cost Changing source code by customers leads to control issues Proprietary is reliable Proprietary is built on open standards Proprietary is backed up by warranty and support
- 6. Sept 2014 Proprietary Vs. OSS How much does it cost? Total Cost Total cost of ownership represents the overall cost needs to obtain a product TCO MODEL FOR SERVER OPERATING SYSTEM THOMAS JENSEN AND SHAKIL AHMED ICCIT 2010 SW TCO Cost for licensing Cost of initial installation and setup Running cost Cost for warranty and support Switching cost Licensing: Dual-licensing firms sell a commercial license for the same OSS product that doesnt require the applications source code to be licensed Some vendors need enterprise license for OSS to give support (SAP with Linux Enterprise licenses)
- 7. Sept 2014 Proprietary Vs. OSS Issues with reliability Proprietary testing and releasing is very rigorous Having source code available increases the chances to exploiting the SW and finding security holes and glitches Open source communities introduce individual changes with no real integration
- 8. Sept 2014 Proprietary Vs. OSS Vendor lock-in Commercial applications are on different infrastructure and OSs Proprietary applications are built on open standards SOA architecture allows reuse and application sharing Lock-in issues will be similar in OSS for large enterprises (migration and switching costs)
