Issues in moving from web services to service orientation

Purpose - To carry out a practical experiment into the feasibility of service orientation to achieve a dynamic, late-binding service architecture. Design/methodology/approach - Literature view to provide a foundation in standards and measure anecdotal opinion regarding service orientation. The review informed an architectural design based on real world requirements from a multinational mobile telecommunications organisation moving toward portal-based services. The architectural implementation took place in a lab-based setting and tested with third-party services that were integrated into the architecture dynamically to test the late bound requirements of the infrastructure. The experimental approach also enabled the testing of the opinions formed regarding service orientation. Findings - The main outcome of the study related to the open, standards-based nature purported to be possible with service orientation. The findings on the study highlighted some major problems in interoperability and operational efficiency of service-oriented technologies when applied to a complex architecture framework. Research limitations/implications - Currently this represents the findings of a single study based on a specific set of requirements. In order to generalise, further study is needed and currently ongoing. Practical implications - The study has high implications for people wishing to approach service orientation as a means to integrate both new and legacy systems. The work raises a lot of questions about the supposed ease of integration. Originality/value - The work contributes to a growing body of work examining and evaluating the usefulness of service orientation.
