Towards A Nature Inspired Self Organizing Service Oriented Architecture

Development of internet and World Wide Web
technologies has enabled access to many types of services over the
web. Large and complex computational units can be built /
composed out of the available services. This type of concept and
architecture is called Service-Oriented Architecture (SOA).
Implementation of SOA brings about challenges which include
service discovery, service interaction, service composition,
robustness, quality of service, security, etc. These challenges are
mainly due to the dynamic nature of SOA. SOA may often need
to dynamically (re)-organize its topologies of interactions
between the services due to unpredictable events, such as crashes
or network problems, which will cause services unavailability.
The dynamic characteristic of SOA is quite similar with the
characteristic of self-organizing systems, in the way that they are
able to organize elements (services in the case of SOA) in order to
change their functions or create new functions on higher levels
(emergence). Therefore, we believe that the dynamic
characteristic of SOA can benefit from the use of selforganization
primitives found in nature. In this paper, we
elaborate the idea of adapting self-organizing systems found in
nature into SOA in order to ensure the robustness of SOA, and
the proposed architecture is presented.
