I have a few questions regarding ESB technology and Drupal CMS.
Drupal, it seems, has progressed into a phenomenon much like OpenSource ESB integration technology. Perhaps it's not unreasonable to depict it as a "client-side ESB". Moreover, Drupal has add-on modules to support web service hosting for its "nodes", ready integration with Apache projects like Solr, and a rich ecosystem of other components.
Can anyone please comment on how ESB and Drupal technology may begin to overlap more? Does anyone expect Drupal will be more seamlessly integrated with an ESB (FUSE or other) - or has this already happened? Are these technologies likely to eventually converge?
Also, what does the space of problems best solved by Drupal vs. ESB integration patterns look like?
