Using open source libraries in companies with a high level of management and risk (banks, finance, etc.)

Does anyone have good stories about how these organizations are open to using open source dependencies (as well as tools). Many of the employees I came across have little or no open source / systems exposure, and open source is viewed with great suspicion. Some of the reasons given for this are the lack of support and reliability, which is ironic given the number of unsupported products from suppliers that are in production.

I’m also interested in any success stories where you have seen how open source companies are part of such organizations, and it really benefits!

I have been working on a huuuuge project in the financial industry (> 100,000 person-days, several hundred million euros) for almost three years, from the beginning of 2003 to the end of 2005, and we used a lot of open source software there. Let me list a few (at least a few critical):

  • Maven 1.0 beta 8 - to create a decent amount of LOC (from the very beginning of the project)
  • Hibernate 2 - we needed lazy loading, L2 cache (introduced in 2004)
  • EHCache - for the second level cache (we have implemented and introduced JMS replication after too much battle with JGroups)
