  • 需要大容量内存
  • 运行数小时到数周

推理工作负载:

  • 需要低延迟
  • 受益于批处理优化
  • 需要快速自动扩展
  • 持续运行

  1. 特征存储: 训练和推理的一致特征计算
  2. 向量数据库: RAG和嵌入应用的相似性搜索
  3. 数据湖: 训练管道的原始数据存储
  4. 模型注册表: 版本控制的模型存储和部署
  5. 工件存储: 训练工件、检查点和日志

      checkpoints: 30_days
      logs: 90_days
      metrics: 365_days

原则3:AI网络架构

AI工作负载有独特的网络需求:

训练网络:

  • GPU节点之间的高带宽(100+ Gbps)
  • 梯度同步的低延迟
  • 分布式训练的RDMA支持

推理网络:

  • 低延迟服务的全球分布

AI的多云和混合策略

为什么AI需要多云?

战略原因:

  1. GPU可用性: 没有单一提供商有无限的GPU容量
  2. 成本套利: 提供商之间的定价差异显著
  3. 专业能力: 不同提供商在不同AI服务上表现出色
  4. 风险缓解: 避免单一提供商依赖
  5. 监管要求: 数据主权要求

战术原因:

  1. Spot/可抢占容量: 跨提供商最大化
  2. 地理覆盖: 通过本地推理服务全球用户
  3. 模型可移植性: 在任何地方训练,在任何地方部署

混合云:何时选择本地部署

有利于本地AI的场景:

  1. 数据主权: 法规禁止云存储
  2. 一致工作负载: 可预测的需求有利于自有基础设施
  3. 低延迟需求: 边缘/本地减少网络跳数
  4. 敏感工作负载: 最大安全需要物理控制
  5. 规模成本: 非常大的部署本地可能更便宜

AI主权云:合规和控制

AI主权的兴起

全球政府正在实施AI特定的法规:

欧盟AI法案: 要求高风险AI系统的透明度、文档和数据治理

美国行政命令: 联邦机构必须确保AI安全并管理算法风险

亚太法规: 各国实施数据本地化和AI伦理要求

企业影响:

  • 训练数据通常必须留在国内
  • 模型权重可能是受监管资产
  • 推理日志需要保留和审计
  • 跨境AI部署面临限制

构建主权AI基础设施

主权要求框架:

要求实现方式
数据驻留区域云部署、加密
处理位置受监管地区的专用计算资源
访问控制本地管理控制、审计日志
密钥管理客户管理的密钥、本地HSM
审计合规全面日志记录、保留策略
模型治理版本控制、血缘追踪

  2. 拥抱多云——没有单一提供商可以满足所有AI基础设施需求
  3. 规划主权——监管要求正在全球扩展
  4. 不断优化——没有仔细管理,AI基础设施成本可能失控
  5. 安全是基础——AI系统带来需要特定控制的独特安全挑战

您今天做出的基础设施决策将决定您未来几年的AI能力。深思熟虑地构建,有意识地扩展,持续迭代。
