WebSphere Enterprise Service Bus (WESB) and the IBM Integration Bus successor product

Content

The information in this document is based on IBM current product plans and strategy, which are subject to change by IBM without notice.

IBM Integration Bus represents the IBM strategic Enterprise Service Bus (ESB) offering, and is the successor product for existing clients of both WebSphere Message Broker and WebSphere Enterprise Service Bus. Learn more about IBM Integration Bus.

Further WebSphere Enterprise Service Bus releases are not planned. The final WebSphere Enterprise Service Bus release is version 7.5.

End of Support has been announced as April 30, 2018 for WebSphere Enterprise Service Bus version 6.2, version 7.0 and version 7.5. See Software withdrawal and discontinuance of service: Select IBM WebSphere Enterprise Service Bus products - Replacements available for details.

There is no immediate need to move off WebSphere Enterprise Service Bus Version 7.5 in 2014. However, planning for that move should begin and you should contact your local IBM Account Team about this process. Briefings on this Enterprise Service Bus strategy, IBM Integration Bus, cost neutral entitlement transfer from WebSphere Enterprise Service Bus to IBM Integration Bus and the WebSphere Enterprise Service Bus to IBM Integration Bus artifact conversion are available. We strongly recommend using IBM Integration Bus for new integration projects

For additional insight useful to all IBM WebSphere Enterprise Service Bus clients, see this Hangout with IBM Integration architects Rob Phippen and Matt Lucas.
