What is Open Source?

Open-source software is an antonym for closed source software and refers to any computer software whose source code is available under a license (or arrangement such as the public domain) that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form. It is often developed in a public, collaborative manner. It is the most prominent example of open source development and often compared to user generated content.(Source: http://en.wikipedia.org/wiki/Open_source_software)

Why Consider Open Source?

The price is right! Typically more secure Easier access to customization Access to innovation Global collaboration

Concerns with Open Source

Support is dependent on project “Patches” typically mean “upgrade.” Backwards compatibility sometimes a

problem Integration with proprietary solutions

sometimes a problem

Myths Involving Open Source

“I will get sued for using Linux” “The savings of open source are overwhelmed

by the costs to implement” “Switching to open source software is harder

than staying with Microsoft over time.” “Free software doesn't come with any support.” “Open source is never as good as the stuff you

pay for.”
