Micro-modularization of embedded systems
These modules, or micro modules, are designed to perform a specific, well-defined function and interact with other modules through clearly defined interfaces. In many products, this model is still appropriate. Problems arise when a device stops being a “closed project” and instead remains in. We present a collection of tools for building plug-and-play modular physical computing systems that we call Modular-Things. Microservices modules in microservices architecture for IoT apps communicate with each other via lightweight protocols (such as. Abstract- This paper explores the strategic implementation of microservices architecture as a transformative approach to achieving modularity and scalability in enterprise systems. In this talk at the Embedded Open Source Summit 2024, Golioth Firmware Lead Sam Friedman talks about how to create “microservices” for microcontrollers. After Microservices became popular, people realized that the structure of a system is very important. The basic concept of modularization is not new, however.
