The document discusses an IoT workshop presentation about Zetta, an open source API-first platform for building IoT applications. Zetta addresses common issues with IoT like different protocols, security, and managing large numbers of devices. It uses HTTP to communicate between devices and generates APIs from Node.js code. Zetta also makes it easy to coordinate devices globally, broadcast data via websockets, and develop tools for IoT applications. The architecture involves lightweight Zetta processes running on edge network devices and servers that communicate securely to manage devices and proxy HTTP requests.

11. Solving these problems
● Interfaces and Protocols
● Use HTTP to communicate with devices
● Every device gets an API generated from Node.js
● Devices in large systems
● Coordinate devices across the globe with ease
● Quality of Tooling
● Designed with the developer in mind
● Multiple tools for helping develop quickly
● Data
● Broadcasting data over websockets
● Make collection and analysis easy

19. Architecture Notes
● Zetta is a lightweight process that lives in multiple places
● First on the edge of the network on a hardware hub
● Second in a datacenter or on a cloud server
● Zetta will mediate protocols in the hardware hub
● Separation between API tech and Device protocol tech
● Zetta processes establish a secure link between each other using the
Z2Z protocol.
● Zetta maintains a layered approach keeping components pluggable
and extensible

21. Device Definitions
Devices are modeled as simple state machines in JavaScript. Then they
are rendered on a by state basis in the API.
