Technology Stack
This page summarizes the main technologies IoT DC3 currently runs on and recommends for local development. Treat
pom.xml, dc3-web/package.json, and docs/package.json as the source of truth for exact versions; the README keeps
only a short reader-facing summary.
Backend and Center Services
| Area | Technologies | Purpose |
|---|---|---|
| Language and frameworks | Java 21 · Spring Boot 4 · Spring Cloud 2025 | Runtime foundation for the gateway, center services, and driver processes |
| AI integration | Spring AI 2.0 | Agentic Center integration with OpenAI-compatible providers, Tool Calling, and MCP workflows |
| Web and API | Spring WebFlux · Spring Security · springdoc-openapi | HTTP APIs, authentication and authorization, and aggregated API docs |
| Service collaboration | gRPC · Protobuf · Facade interfaces | Strongly typed contracts between center services |
| Build | Maven 3.9+ | Multi-module build, tests, packaging, and dependency version management |
Data, Messaging, and Scheduling
| Area | Technologies | Purpose |
|---|---|---|
| Primary storage | PostgreSQL | Business data, tenants, resources, device models, and runtime data |
| Time-series and extensions | TimescaleDB · AGE · pgvector | Point history, graph capabilities, and vector capabilities |
