DC3: Open-Source Spring Cloud IoT Platform Architecture & Modules

Introduction

DC3 is an open-source, distributed Internet of Things (IoT) platform built on Spring Cloud. It provides a complete solution for rapid IoT project development and device management.

Project Advantages

Scalable: Horizontally scalable platform built with leading Spring Cloud open-source technology.

Fault-tolerant: No single point of failure; every node in the cluster is 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: Java-based deployment supports remote, distributed, multi-platform deployment.

Self-controllable: Supports private cloud, public cloud, and edge deployment.

Comprehensive: Fast device access, registration, and permission verification.

Security (in development): Encrypted data transmission; MQTT driver already implements encrypted transmission.

Multi-tenant: Namespace-based multi-tenancy.

Cloud-native: Kubernetes support.

Containerized: Docker support.

Module Division

The platform follows a four-layer architecture:

Driver Layer: Provides SDKs for standard or proprietary protocols to connect physical devices. Responsible for southbound device data collection and command control. The SDK enables rapid driver development.

Data Layer: Handles device data collection and persistence, and provides data management interface services.

Management Layer: Core microservice interaction layer providing service registry, device command interfaces, device registration and pairing, and data management center. Manages configuration data and exposes interface services.

Application Layer: Provides data openness, task scheduling, alarm and message notification, log management, and third-party platform integration capabilities.
