## ✨ Core Features

### 🔌 Multi-Protocol Device Connectivity

IoT DC3 includes **28 access driver modules** for industrial automation, IoT communication, data bridging, basic
communication, and simulation/debugging scenarios, reducing the cost of connecting common devices and data sources:

| Category                           | Driver Modules                                                                                                                                     |

The **Driver SDK** supports fast development of custom protocol drivers and registration into the runtime platform.

### 🤖 AI Capability Integration

The agentic center is built on **Spring AI** and connects large language models into IoT operations workflows:

- **Natural-language device operations** - LLMs can query devices, read/write points, and execute commands through Tool
  Calling
- **Intelligent alarm analysis** - AI assists with root-cause analysis and response suggestions
- **Data insights** - Query device data in natural language and generate visual charts
- **Multi-model support** - Compatible with OpenAI API-style providers and mainstream models such as GPT, Claude,
  DeepSeek, and Qwen
- **Conversation memory** - Multi-turn conversations and context memory persisted to the database

### 🏗️ Cloud-Native Microservices

Distributed microservice architecture based on **Spring Boot 4 + Spring Cloud 2025**:

- **Service governance** - Spring Cloud Gateway as the unified entrypoint, with static routes and flexible environment
  variables
- **Efficient communication** - gRPC service calls with Protobuf serialization
- **Horizontal scaling** - Stateless design for scaling individual services by workload
- **Resilience** - Replaceable service nodes and fault isolation

### 📊 Real-Time Data Engine

- **Data collection** - Drivers collect device telemetry and send it asynchronously through RabbitMQ
- **Time-series storage** - Efficient queries for real-time and historical data
- **Rule engine** - Flexible alarm rules with multi-level alarms and notifications
- **Event traceability** - Full command and event history

### 🔐 Enterprise Security and Multi-Tenancy

- **Tenant isolation** - Tenant-level isolation across database, cache, and API paths
- **Authentication and authorization** - JWT + Spring Security with RBAC
- **Transport encryption** - TLS/SSL communication support
- **Audit tracking** - User operation and system event logs

### 🧩 Developer Friendly

- **Driver SDK** - A complete driver development toolkit. See
  the [Driver Authoring Guide](https://pnoker.github.io/iot-dc3/development/driver-authoring.html)
- **Separated frontend and backend** - Vue 3 + TypeScript frontend, RESTful and gRPC APIs
- **Containerized deployment** - One-command startup with Podman / Docker Compose, with a path toward Kubernetes and
  other container platforms
- **Complete documentation** - Online docs, quickstart guide, and troubleshooting guide

## ⚡ Quick Start

### Prerequisites

| Dependency       | Version       |
|------------------|---------------|
| Java (JDK)       | 21+           |
| Maven            | 3.9+          |
| Podman or Docker | Latest stable |

### Start in Three Steps

**① Clone the repository**

```bash
git clone https://github.com/pnoker/iot-dc3.git
cd iot-dc3
```

**② Start base dependencies** (PostgreSQL + RabbitMQ)

```bash
# Global registry
make up-db

# Mainland China users (Alibaba Cloud registry)
make up-db-cn
```

**③ Load local environment variables, build, and start**

```bash
source dc3/env/dev.env.sh
mvn -s .mvn/settings.xml clean package
```

`dc3/env/dev.env.sh` points local Java processes to the PostgreSQL, RabbitMQ, and gRPC ports published on `localhost`.
Run the following `java -jar` commands in the same terminal session.

Start services in order:

```bash
java -jar dc3-gateway/target/dc3-gateway.jar                          # API Gateway
java -jar dc3-center/dc3-center-auth/target/dc3-center-auth.jar        # Auth Center
java -jar dc3-center/dc3-center-manager/target/dc3-center-manager.jar  # Manager Center
java -jar dc3-center/dc3-center-data/target/dc3-center-data.jar        # Data Center
java -jar dc3-center/dc3-center-agentic/target/dc3-center-agentic.jar  # Agentic Center
java -jar dc3-driver/dc3-driver-virtual/target/dc3-driver-virtual.jar  # Virtual Driver for demos
```

> 📖 For full local setup, see the [Quickstart](https://pnoker.github.io/iot-dc3/quickstart/) and
> [Environment Variables](https://pnoker.github.io/iot-dc3/quickstart/environment.html) docs.

<details>
<summary>🔧 More startup options (optional dependencies, single-service startup, environment variables)</summary>

**Start optional infrastructure** (EMQX, ELK/APM, Prometheus, Grafana, etc.):

```bash
make up-optional-cn              # Start optional dependencies
make up-db-cn && make up-optional-cn && make up-dev-cn  # Start all dependencies
```

**Start selected services** (useful for frontend/API testing):

```bash
make up SERVICES=agentic REGISTRY=cn               # Single service
make up SERVICES="gateway agentic" REGISTRY=cn      # Multiple services
make up GROUP=core REGISTRY=cn                      # Core service group
make up GROUP=drivers REGISTRY=cn                   # Driver service group
make logs SERVICES="gateway agentic"                # Follow logs
```

**Compose environment overrides**:

```bash
cp .env.example .env    # Copy the template
```

The root `.env` file is used for Compose variable interpolation, such as image registry, image tag, and published ports.
Application runtime variables are configured in `dc3/env/dev.env`. See
the [environment documentation](https://pnoker.github.io/iot-dc3/quickstart/environment.html).

## 🏗️ Architecture Overview

![IoT DC3 Architecture](dc3/images/iot-dc3-architecture-en.svg)

| Layer                 | Responsibilities                                                                                                                 |
|-----------------------|----------------------------------------------------------------------------------------------------------------------------------|
| **Driver Layer**      | SDK-based driver development, standard/proprietary device access, southbound data collection, and command execution              |
| **Data Layer**        | Device data collection, storage, and query services for real-time and historical data                                            |
| **Management Layer**  | Microservice collaboration core: service registration, device/driver management, command orchestration, configuration governance |
| **Application Layer** | Data openness, scheduling, alarms, logging, third-party integration, and AI automation                                           |

🧱 **Design principles** — cross-service calls always go through Facade interfaces; the DO/BO/VO three-tier model keeps persistence, business, and API shapes strictly separated; and tenant isolation runs end to end across database, cache, and API paths. Clear boundaries that scale across services and teams.
