CEO / CTO ZettaScale Technology Angelo Corsaro, PhD Zetta The Cloud to Microcontroller Platform 

The Problem 

Cloud to Microcontroller Today, more and more systems, operate from the cloud down to the micro-controller This poses new challenges as existing technologies were not designed to work in this scenario Cloud Edge Device 

A Cross Industry Challenge Robotics Automotive IoT / Edge … 

Simplicity does not precede complexity, but follows it — A. Perils Digital Frankensteins Today, building systems that span from the micro-controller to the data-centre feels like assembling a digital Frankenstein Multiple technologies are stitched together only to make data fl ow end-to- end Few more have to be packed-up to deal with data storage… Not to mention computations 

The Solution 

Core Technology 

Dragons teach us that if we want to climb high we have to do it against the wind. Pub/Sub/Query protocol that Uni fi es data in motion, data at rest and computations from embedded microcontrollers up the data centre Provides location-transparent abstractions for high performance pub/sub and distributed queries across heterogeneous systems Support for distributed data- fl ow programming through Zenoh-Flow 

Zenoh Implementations ZettaScale leads two implementations of the Zenoh protocol Zenoh written in Rust and Zenoh Pico written in C and targeting micro- controllers When using C/C++ APIs, applications can target either of these versions — it is a compile-time decision C C CPP Zenoh Pico Zenoh C Rust CPP Python Kotlin Java TS Rust Go JS 

Supported OS OS Linux, MacOS, Windows, Android, iOS, QNX Embedded Targets Arduino, ESP32, mbed, Zephyr, FreeRTOS, … Automotive Targets AUTOSAR Classic (microSAR) 

Runs Everywhere Written in Rust for security, safety and performance Native libraries and API bindings for many programming languages, e.g., Rust, C/C++, Python, JS, REST, C# and Kotlin Built-in support Shared Memory and Zero Copy Supports network technologies from transport layer down- to the data link. Currently runs on, TCP/IP, UDP/IP, QUIC, Serial, Bluetooth, OpenThreadX, Unix Sockets, Shared Memory Available on embedded and extremely constrained devices and networks — 5 bytes minimal overhead Data Link Network Transport Physical …

Platform 

Technology vs Platform Zenoh is the core technology invented to address the challenges of communicating, storing and computing in the cloud-to- microcontroller continuum You can use this technology at the core of your platform for supporting your systems, but that will take you away from you core- business 

Zetta Platform The Zetta Platform provides the ideal solution to support the development, integration, deployment and operation of systems spanning from the cloud to microcontroller 

Zetta Z-PaaS. Zetta Platform as a Service supporting multi- cloud developments, public/private clouds and able to manage on-premise Z-Routers Z-Router. Zetta’s Zenoh router. Can be used stand- alone or integrated with Z-PaaS Z-Connectors. Connectors to protocols, e.g., DDS, MQTT, etc., and Data Bases, e.g. RocksDB, In fl uxDB, etc. Z-Tools. A rich set of tools supporting monitoring, management, administration, debugging, etc. Z-API. Programming API for a variety of programming languages and targets, e.g., Python, C/C++, Rust, Arduino, etc. Z-PaaS Z-Router Z-Connectors Z-Tools Z-API 

What Does This Mean? I can use Zenoh from the microcontroller up to the datacenter, including mobile and web applications. The Zetta PaaS allows me to easily secure, provision, manage, and operate the Zenoh infrastructure require to scale and operate my system at Internet Scale. Green Field Development. 

What Does This Mean? I can continue to use DDS, MQTT, or another protocol in my existing system, as well as for part of the new development. I can leverage a Z-Connector to my protocol to unlock the use of Zenoh, or any other protocol for which there is a connector anywhere else Brown Field Development

Final Remarks The Zetta platforms provide the ideal solution for building your next generation system as well as incrementally expanding exiting solutions It eases integration and ensures that even in brown- fi eld development you can leverage the power for Zenoh 

Patience, persistence and perspiration make an unbeatable combination for success. Thank You
