CORBA and provides

PolyORB provides a uniform solution to build distributed applications relying either on middleware standards such as CORBA, the Ada 95 Distributed System Annex, SOAP, Web Services, or to implement application-specific middleware.

CORBA and communication
Message-oriented technologies attempt to relax tightly coupled communication ( such as TCP network sockets, CORBA or RMI ) by the introduction of an intermediary component.
Issues not addressed here, yet accounted for in the CORBA specification, include data typing, exceptions, network protocols, communication timeouts, etc.
Most of the popular open source ORBS, such as TAO and JacORB also support bidirectional GIOP, which gives CORBA the advantage of being able to use callback communication rather than the polling approach characteristic of web service implementations.
Since both processes can access the shared memory area like regular working memory, this is a very fast way of communication ( as opposed to other mechanisms of IPC such as named pipes, Unix domain sockets or CORBA ).
