This article presents the architecture, design and validation of a
microservice orchestration approach, that improves the flexibility of
heterogeneous microservice-based platforms. Improving user experience
and interaction, for time-critical applications are aspects that were
primary objectives for the design of the architecture. Each microservice
can provide its own embedded user interface component, also
decentralizing it and, in consequence, improving the loosely coupled
approach to the architecture. Obtained results are promising, with high
throughput and low response times. Also, a key finding was the
introduction of benchmarking as a new step in the development lifecycle
of performance-critical software components, with an example of how it
can be applied within an Agile methodology. Further research is proposed
to improve the results and raise the final technology readiness level of
the system. Obtained results already make the approach a candidate and
viable alternative to classical service composers.
