IoT DC3 is an open-source distributed Internet of Things (IoT) platform based on Spring Cloud. It is used for rapid development of IoT projects and management of IoT devices, providing a comprehensive solution for IoT system development.

1Architecture

Driver Layer: Provides SDKs for connecting physical devices via standard or proprietary protocols, responsible for southbound data collection and command control. The SDK enables rapid driver development;
Data Layer: Responsible for collecting and storing device data, and providing data management interface services;
Management Layer: Provides a microservice registry, device command interfaces, device registration and pairing, and a data management center. It is the core part of all microservice interactions, managing various configuration data and providing external interface services;
Application Layer(partially completed): Provides data openness, task scheduling, alarm and message notifications, log management, and the capability to integrate with third-party platforms.

2 Target

Scalable: A horizontally scalable platform built using leading open-source technology, Spring Cloud;
Fault Tolerant: No single point of failure, with each node in the cluster being identical;
Robust and Efficient: A single server node can handle even hundreds of thousands of devices depending on the use case;
Customizable: Add new device protocols and register them to the service center;
Cross-Platform: Compatible with Java environments, enabling distributed multi-platform deployment;
Autonomous and Controllable: Supports private cloud, public cloud, and edge deployments;
Comprehensive: Fast device onboarding, registration, and permission validation;
Secure: Data transmission is encrypted;
Multi-Tenant: Supports namespaces and multi-tenancy;
Cloud-Native: Kubernetes;
Containerized: Docker.
