Next generation large-scale distributed systems – such as smart cities – are dynamic, heterogeneous and multi-domain in nature. The same is true for applications hosted on these systems. Application heterogeneity stems from their Unit of Composition (UoC); some applications might be coarse-grained and composed from processes or actors, whereas others might be fine-grained and composed from software components. Software components can further amplify heterogeneity since there exists different component models for different domains.
