Recent advancements in IoT and web technologies have highlighted the significance of isomorphic software architecture development, which enables easier deployment of microservices in IoT-based systems. The key advantage of such systems is that the runtime or dynamic code migration between the components across the whole system becomes more flexible, increasing compatibility and improving resource allocation in networks. Despite the apparent advantages of such an approach, there are multiple issues and challenges to overcome before a truly valid solution can be built. In this idea paper, we propose an architecture for isomorphic microservice deployment on heterogeneous hardware assets, inspired by previous ideas introduced as liquid software [12]. The architecture consists of an orchestration server and a package manager, and various devices leveraging WebAssembly outside the browser to achieve a uniform computing environment. Our proposed architecture aligns with the long-term vision that, in the future, software deployment on heterogeneous devices can be simplified using WebAssembly.
