    Status of FUSE ESB 4

    Andrew Headrick Newbie



      I am charged with choosing and deploying an ESB solution for my company.


      I am curious as to the status of Fuse ESB 4. I know there are some big changes (OSGi vs. MBeans and JMX) and backwards compatibility issues ( drools 3 vs. drools 4 ) with the new version. I am hesitant to deploy FUSE ESB 3 if there are going to be many issues with upgrading.


      Is it a better idea to deploy FUSE ESB 3 and upgrade to 4 when it is out? Or, is it better to deploy ServiceMix 4 and migrate to FUSE 4 when it is stable?


      Any thoughts?


      Thanks in advance,

          Hi Andrew,


          We would normally recommend the latest release ESB 4 however this does depend on the timeframes for your project.


          FUSE ESB 4.0 Preview 1 is now available for download. This preview release is suitable for pilot projects however the product needs some additional development, testing and user feedback before it should be used in mission-critical production environments. This Preview Release of FUSE ESB 4.0 will be followed by a Generally Available (GA) release on September 8th.


          If you require a GA release before September and start your project with ESB 3 then a Migration Guide is being developed which covers the considerations when migrating applications from FUSE ESB 3.x to 4.x.

            Hello, it's September 12th and still only the preview is availaible.

            I'm starting a new project and I'm evaluating the ESB implementation to be used. As the project is starting now and we will not have a prototype version until the end of this year, I would like to know the state of FUSE ESB 4 and its stability and features on a short period (september-december '08).

            Is it better to start with FUSE ESB 3 instead? Does FUSE ESB 4 provide some advantages in performance, features or easy development right now? Is it difficult to migrate from version 3 to version 4?

              We have extended the preview period for ESB 4 in order to incorporate more of the feedback we have received into the final product.


              The revised schedule is 


              ESB 4 Preview 2   22nd Sept

              ESB 4 GA            13th Oct


              For a new project we would recommend that you use ESB 4 as it offers improved ease of use and support for the latest standards like OSGi and JBI 2.0.


              We would welcome your feedback on ESB 4 preview releases.


              best regards,
