AI Infrastructure Stack
Definition
The layered architecture of technologies that support the end-to-end AI lifecycle, from compute hardware to application deployment and governance. Industry consensus has converged on a six-layer model.
支持端到端人工智能全生命周期的技术分层架构，涵盖从计算硬件到应用部署与治理。行业共识已形成六层模型。
Details
Six-Layer Architecture (IBM)
| Layer | Components |
|---|---|
| Infrastructure | GPU/TPU/ASIC, storage, networking |
| Data | Ingestion, preprocessing, labeling, vector DBs |
| Model | Frameworks (PyTorch, TensorFlow), training, fine-tuning |
| Deployment | Containers, serving, APIs, inference optimization |
| Application | Business integration, agent frameworks, UIs |
| Observability | Monitoring, compliance, ethics, governance |
| 层级 | 组件 | |-------|-----------| | **基础设施** | GPU/TPU/ASIC、存储、网络 | | **数据** | 采集、预处理、标注、向量数据库 | | **模型** | 框架 (PyTorch, TensorFlow)、训练、微调 | | **部署** | 容器、服务化、API、推理优化 | | **应用** | 业务集成、智能体框架、用户界面 | | **可观测性** | 监控、合规、伦理、治理 |
