Internetware systems. The key enablement of ARM is runtime architecture infrastructure (RAI) that maintains the causal connection between runtime systems and architectural models. An RAI is uneasy to implement and, more importantly, specific to the given system and model. In this paper, we propose a model-driven approach for automated generation of RAI implementation. Developers only need to define three MOF models for their preferred architecture model and the target system (these models are reusable independently for different pairs of the model and system), and one QVT transformation for the causal connection. Our Eclipse-based toolset, called SM@RT, will automatically generate the RAI implementation code without any modification on the source code of the target system, and automatically and properly deploy the generated RAI into the distributed systems. This approach is experimented on several runtime systems and architectural models, including ABC architectural models on Eclipse GUI and Android, C2 architectural models on JOnAS, Rainbow C/S style on PLASTIC and UML models on POJO.
