Tim believes that open source, at least as defined by open-source licensing, has a short shelf life that will be consumed by Web 2.0 (i.e., Web companies hijacking open-source software to deliver proprietary Web services) or by traditional proprietary software vendors.

In various markets, open source has relentlessly driven prices down while boosting performance and customer value, as detailed by The 451 Group. Even as traditional vendors have struggled with a tight economy, open-source vendors have thrived.

Werner Knoblich, vice president and general manager of the company's Europe, Middle East and Africa region, tells Computing about successful open source subscription models, ongoing battles with proprietary vendors for a level playing field, and opportunities for open source software in cloud computing.

A common question you hear from proprietary vendors when dismissing open source alternatives is “how many customers actually want access to the code anyway?” It is a question I put to an open source software vendor myself earlier this week while playing devil’s advocate.

Over the last couple of years a number of different open source business strategies have evolved. According to the 451 Group, it's an evolution that includes the broader adoption and usage of open source overall by both open source and proprietary software vendors.

Granting that the open source players are starting out from a small revenue base, simple math tells us that if they keep on growing at their present pace they will sooner or later put some real hurt on the sales of incumbent closed source vendors like IBM and Oracle, who have long dominated enterprise middleware and database sales.

Bob Sutor discusses the effect of open source and open standards on innovation and markets. Specific topics include the effects of open source alternatives on software markets, open standards and interoperability, the new social aspect of software and the open source community.

As businesses look to become less dependent on software vendors to solve their integration issues there is a groundswell of support for open source solutions. For companies already using open source, a survey of IT decision makers by Forrester earlier this year found that 51% were using it in mission-critical applications.

JBoss developer Roy Russo wonders if all open-source companies are de facto monopolistic. Like many others that I respect (Dave Rosenberg, Lonn Johnston, President Bush, Oscar the Grouch), Russo says any market ultimately has room for only one purveyor of free software.
