| Abstract |
|
Large monolithic business systems, as for example
the business suite Mysap from SAP, are increasingly
restructured in system architectures with fine-granular
components, which are loosely coupled by Web
services. Their intra-system collaboration has usually
no need for dynamic discovery with UDDI. Those
architectures show many advantages, but cause also a
performance problem which might become an inhibitor
to their use in operational systems. We experienced
that problem with I^3 M, an instant messaging system we
developed and present as an example. Measurements
with I^3 M show that the performance overhead of Web
service invocation among collocated system
components may decrease the system performance
dramatically. We propose a solution to the
performance problem that preserves the benefits of
Web service invocations, but provides the performance
of "normal" component invocations.
