DXC Technology 基于 Amazon Bedrock 搭建多模型 AI 底座
How DXC Technology built a multi-model AI substrate on Amazon Bedrock
DXC 在 70 国做 IT 托管服务，把 AI 架构拆成 Bedrock 多模型底座加自建治理层，agent 的编排、权限、审计全走一套 harness。做企业级 agent 落地的开发者值得看它的分层设计，尤其受监管行业的团队。
DXC Technology 为 70 个国家的受监管客户运营关键任务 IT 托管服务，其在 Amazon Bedrock 上构建了名为 DXC OASIS 的 Human+AI 运营模式。该架构的核心思路是把架构拆成两层：一层是具备弹性的多模型底座，另一层是负责编排、治理和审计 AI agent 的 trusted harness。
在技术机制上，DXC 通过 Amazon Bedrock 接入多个基础模型，避免绑定单一模型供应商；trusted harness 层则统一管理 agent 的调度、权限和审计日志，使 AI 自动化在合规要求严格的行业里仍可被监督和追溯。这种分层设计让模型可以随时替换或升级，而治理层保持稳定。
对于在金融、医疗等受监管行业部署 AI agent 的企业来说，这个案例展示了如何用托管服务（Bedrock）加上自建治理层来平衡自动化效率与合规审计需求，其架构拆分思路也可借鉴到非 Bedrock 的技术栈中。
