  • Speaker's notes capitalizing on Bull’s industrial infrastructure, and offering customers a highly transparent, interactive approach
  • Speaker's notes : Today, it is less necessary to defend Open Source than before. To choose Open Source, it's a strategical choice : you choose to invest in brain instead in licences. We will see that there are alternative to (more less) all proprietary solutions.
  • Speaker's notes : Often, at the start of an Open Source project, there is the need from some people. The need to have a particular solution, an answer to a precise need. The first developments are done as hobby, after the day work, when Madam is visiting her mother, ... Afterwards, when the success is need (wanted or unwanted), the community get wider and wider, the roles inside her become more formal. Methodologies for Project Management and various procedure are put in place. Sometimes, some commercial companies who found the project interesting hire people with only job to participate into the development of his project. The purpose being to participate to the perennity of the project and to grab more know-how about the project for its own use And finally it can be that a part of the developers create a commercial company to sell services (support, integration) around this solution and continue to extend it. Howeve, nowadays, since their birth, some Open Source projects are created by a commercial company, made for this simple goal.
  • Speaker's notes : To obtain the same level of performances (let's say transactions per second) for the same application but on two different architectures, the investment for an Intel infrastructure is far less than the investment for RISC, SPARC or other able to achieve the same level of performances.
  • Speaker's notes For some projects (like ERP or SOA) you will need to have tailor-made developments, so why not to cut the cost at the early beginning and start with solutions like CompiereERP or ServiceMix that don't cost a cent in licences. Usually, the free versions of the commercial Open Source solutions have less features. But there are still viable and usable as-is. The features you get when you bought the commercial version generally address a particular need. For instance, in the case of Mail Server solution, when you pay, you get an Outlook connector. If you don't pay, you can still use any client using standard protocol like POP, IMAP or HTTP.
  • Speaker's Notes : It's more about control of your internal systems, schedules, and business processes. It's about the ability to patch specific annoyances and/or bugs and to prevent yourself from being locked in to the vendor's schedule for doing so. It's a very big deal !
  • Speaker's Notes Bull capitalizes on his industrial infrastructure, and offers customers a highly transparent, interactive approach. The Bull SOA platform is a unified framework for building, integrating and deploying distributed applications consisting of Open Source middleware products, supported and enhanced by Bull Bull's NovaForge is an internal tool used by Bull to capitalize on other Open Source development and to create a collaborative community of Open Source developers within the whole group. It's similar to the well-know SourceForge site.
  • Speaker's notes Taken from an interview of Boris Auché, Head of Bull's Open Source Solution Group

    • 1.
        • Benoit Gerrienne - IT Consultant
      OpenSource - Why is it good for you ?
    • 2. Agenda
      • What is Open Source ?
      • From .org to .com
      • Benefits of Open Source for you ?
      • You, Bull and Open Source
      • Trends
      • Some realisations
    • 3. What is Open Source ?
      • Open Source, Free Software or « Logiciel Libre »
        • All the code is available
        • Not as Free Beer
        • Can cost something
        • Free as Free to change
      • But it is not Freeware
        • You doesn't pay
        • The code may be available
      • Use different licence models (GPL, LGPL, ...)
        • What you can and cannot do
    • 4. From .org to .com
      • At the beginning, there were communities
        • People having other main occupation
        • Documentation can be missing
        • Support is « best effort »
      • Then appeared the OSS Service Companies
        • Like Bull , offering commercial support
      • Today we see more and more Open Source ISV
        • Produce one solution
        • Offer support contracts, even 24/7.
        • Operate like other ISV's (Oracle, ...)
        • Web Communities to enhance their software
    • 5. Benefits of Open Source for you (1)
      • Low cost Intel architecture
        • Intel architecture is cheaper
        • Maintenance costs are also cheaper
        • Intel is reliable as its competitors
        • Virtualization can increase cost cut
        • 32 bits Intel architecture can compete with any other 64 bits based architecture
    • 6. Benefits of Open Source for you (2)
      • Entry costs are lower
        • Sometimes they are null
        • Commercial Open Source software tends to be cheaper that it's Closed Source counter part
      • Sale's model is different
        • Yearly fee for use and support
        • Free versions exist, good for production
    • 7. Benefits of Open Source for you (3)
      • Access to the source code means
        • Flexibility like your own developments
        • More adaptable to your needs
        • Development teams are huge
          • Quality is better
          • Reactivity is quicker
        • Add your components to the mainstream development
        • You are independent of the ISV
    • 8. Benefits of Open Source for you (4)
      • Fortify user sovereignty in the IT marketplace
      • Simplified licence management
      • Escape to the vendor lock-in
      • You “ control the code ”
        • You have a finer control over the impact of the OSS soft
        • That's no more the vendor that controls you
        • You control the upgrade process
        • You decide which bugs to fix when
        • You decide how big your software budget will be
    • 9. You, Bull and Open Source
