As per title. I don’t know if this is the right place or way to ask this, admins feel free to edit/move/close the question if appropriate.
I’d like to get pointers to recent material clarifying the market trends, as well as real life examples. Even pseudo-pundit, Gartner-like stuff is OK. Thanks.
I am curious about the second part of the question. What is the basis of your statement that ‘the ESB thing’ appears to be fading? I don’t believe it is.
The problem with ESBs however is that some vendors call their product an ESB, but it actually is much much more than that. In some companies this happened with their integration product just because Gartner or some other analysts company says that ESB is hot. Marketing strategy is changed: The product is called ESB and maybe somethings are added that are expected in an ESB.
Paul Fremantle of WSO2 wrote a very good article about what an ESB really is [1].
As for OSGi: The first company I saw using it in their middleware was WSO2. I have heard, that TIBCO, another middleware vendor, is also moving or has moved towards using it in their Active Matrix platform.
OSGi may help in various ways. The most important is that it decreases the effort of the installation of the platform. Install a minimum on each system used to deploy the application, and during deployment the components required to run the application will be added. You do not have to worry about having installed the right plug-ins, add-ons and what not. This is what both WSO2 and TIBCO are doing.
With some vendors, you see that you need to install an awful amount of software, of which you in the end may be using just a small part (e.g. IBM WebSphere). Because of this, you may have to use over-dimensioned systems, which adds extra costs.
OSGi may prevent this.
Have a look at the presentation of WSO2 about the WSO2 Carbon platform [2].
The statement at the end of the presentation says it all:
So yes, I think OSGi has a future in enterprise apps.
