http://wiki.open-esb.java.net/ <--- for OpenESB I dunno, I guess, working with an ESB would be mostly a set of services implemented in Enterprise Message Model. Is there any demand for it? ------------------------------- >From Wikipedia: Key benefits * Faster and cheaper accommodation of existing systems. * Increased flexibility; easier to change as requirements change. * Standards-based. * Scales from point solutions to enterprise-wide deployment (distributed bus). * Predefined ready-for-use service types. * More configuration rather than integration coding. * No central rules engine, no central broker. * Incremental changes can be applied with zero down-time; enterprise becomes "refactorable". Key disadvantages * Enterprise Message Model is usually required, resulting in additional management overhead. May not be a simple task to achieve many disparate systems collaborating on message standards. * Requires ongoing management of message versions to ensure the intended benefit of loose coupling. Incorrect, insufficient, or incomplete management of message versions can result in tight coupling instead of the intended loose coupling. * It normally requires more hardware than simple point to point messaging. New skills needed to configure, manage, and operate an ESB. * Extra overhead and increased latency caused by messages traversing the extra ESB layer, especially as compared to point to point communications. The increased latency also results from additional XML processing, as the ESB normally uses XML as the communication language. * Some critics remark that ESB require a significant effort to implement, but produces no value unless SOA services are subsequently created for the ESB.[1] -------------------------------- Regards Teravus On 3/24/09, [email protected] <[email protected]> wrote: > All, > Suspect the notion of using an ESB with OpenSim would be seen as a feature > request.
