IBM Linux Technology Center © 2006 IBM Corporation  Open Source refers to software in which the source code is available to the general public for use and/or modification from its original design free of charge  The Open Source Model is a pragmatic way of evolving software in a rapidly changing environment.  It harnesses the collective wisdom, experiences, expertise and requirements of its most demanding users to help ensure that their needs are rapidly met.  Community develops, debugs, and maintains  Generally high-quality, high performance software  Peer code reviews are Darwinian: structured and disciplined  More information: Sendmail What is Open Source Software (OSS)?

IBM Linux Technology Center © 2006 IBM Corporation Why does IBM consider Open Source important?  OSS is a good approach for driving emerging standards  Popular Open Source projects can become de facto / open standards  Can have wide distribution and deployment  Can accelerate SOA (Service Oriented Architecture) adoption Wide distribution/deployment  Open Source Software (OSS) can be a major source of innovation  Innovation can happen anytime, anywhere, and might be downstream  Development through “open communities” leads to potentially broad ideas and creativity  OSS is a source of competition and disruption in marketplace  Office productivity applications  Operating systems (Linux for servers, desktops)  Software development environments, …  Community Approach  Internet has changed how enterprises address technical innovation  Enterprises engaging early on with developers  Shapes IBM technical leaders thinking & approach to broad collaboration  Enterprise customers are asking for it  Increase choice & flexibility  Adoption/use of open source can reduce time to market
