Eclipse Theia is an extensible platform to develop full-fledged, multi-language, cloud & desktop IDE-like products with state-of-the-art web technologies. It is implemented in TypeScript, CSS and HTML.
From a birds-eye-view, Theia consists of a frontend, running in a browser or in the local desktop application and a backend running on any host or locally within the desktop application. The frontend and backend communicate through JSON RPC over websockets.
The Eclipse VOLTTRON software platform is Linux-based and capable of running on small, single-board computers as well as in the cloud. It deploys applications known as V-agents that gain access to energy data via automation systems, identifying and diagnosing problems such as erroneous temperature settings. The technology offers passive capabilities that report a problem, as well as active approaches that actually fix the problem. VOLTTRON can be configured to use any protocol needed to interface with devices or data sources.
Early IoT applications, especially those addressing the consumer market, have been embracing cloud-centric architectures in which data is pushed up to the cloud. It is within the cloud the everything takes place before eventually pushing some data or action back to the edge. This architectural approach leverages the availability and operational maturity of the cloud but it is not generally applicable in IoT / Cyber Physical Systems (CPS).
