Moving Application Logic From the Firmware to the Cloud: Towards the Thin Server Architecture for the Internet of Things
Unlike traditional networked embedded systems, the Internet of Things interconnects heterogeneous devices from various manufacturers with diverse functionalities. To foster the emergence of novel applications, this vast infrastructure requires a common application layer. As a single global standard for all device types and application domains is impracticable, the authors propose an architecture where the infrastructure is agnostic of applications and application development is fully decoupled from the embedded domain. In their design, the application logic of devices is running on application servers, while thin servers embedded into devices export only their elementary functionality using REST resources.
