Actor-driven Decomposition of Microservices through Multi-level Scalability Assessment

The microservices architectural style has gained widespread acceptance but designing applications according to this is still challenging. Common difficulties concern finding clear boundaries that guide decomposition while ensuring performance and scalability. With the aim of providing software architects engineers with a systematic methodology, we introduce novel actor-driven strategy complement domain-driven design overcome some its limitations by reaching finer modularization yet enforcing scalability improvements. methodology uses multi-level assessment framework supports decision making over iterative steps. At each iteration, architecture alternatives are quantitatively evaluated at multiple granularity levels. helps understand extent which increase or decrease We applied drive further core real data-intensive smart mobility application an existing open-source benchmark in e-commerce domain. results in-depth evaluation show approach can effectively support in: ( i ) decomposing monoliths coarse grained into more scalable microservices, ii comparing among alternative architectures for their deployment modern infrastructures orchestrate lightweight virtualized execution units.
