This document discusses the Open IoT Cloud architecture proposed by Mokoversity. It describes how IoT is entering a new phase of integration with the Web called the Web of Things. It outlines some key aspects of the proposed Open IoT Cloud architecture, including using RESTful objects and protocols like HTTP, WebSockets, and CoAP to connect physical objects. The architecture aims to be open, decentralized, privacy-respecting and give users control over their personal data.

- 33. Source: http://coap.technology REST model for small devices ! Like HTTP, CoAP is based on the wildly successful REST model: Servers make resources available under a URL, and clients access these resources using methods such as GET, PUT, POST, and DELETE.
- 34. Source: http://coap.technology Made for billions of nodes ! The Internet of Things will need billions of nodes, many of which will need to be inexpensive. CoAP has been designed to work on microcontrollers with as low as 10 KiB of RAM and 100 KiB of code space (RFC 7228).
- 35. Source: http://coap.technology Existing skills transfer ! From a developer point of view, CoAP feels very much like HTTP. Obtaining a value from a sensor is not much different from obtaining a value from a Web API.
- 36. Source: http://coap.technology Ready for integration ! Since HTTP and CoAP share the REST model, they can easily be connected using application- agnostic cross-protocol proxies. A Web client may not even notice that it just accessed a sensor resource! ARM IoT Tutorial https://www.youtube.com/watch?v=4bSr5x5gKvA
