AWS 提供 Textract 跨帳戶 Adapter 管理方案，涵蓋部署、路由與安全
AWS 於 2026 年 9 月 28 日發布 Amazon Textract 指南，介紹如何用 CloudFormation 或 Terraform 管理 Custom Queries adapters，並涵蓋跨帳戶升級、不同表單版本的文件路由及正式環境安全設定。
完整報導
AWS 於 2026 年 9 月 28 日發布 Amazon Textract 文章，說明如何將 Custom Queries adapters 納入正式環境的生命週期管理。這些 adapters 可透過客戶文件範例與訓練，調整文件擷取結果以配合特定文件類型；AWS 也提供 CloudFormation 與 Terraform 範本，供團隊建立相關基礎設施。
文章處理的一項作業挑戰，是把訓練完成的 adapter 推進至其他 AWS 帳戶。AWS 描述的跨帳戶複製流程需要提交 Support 請求，而且傳送的只有訓練後的模型權重，查詢定義與訓練資料不會一併轉移，團隊因此需要在外部保存相關設定。文章也提出集中式 Hub 帳戶作為另一種架構選項。
對包含多種表單版本的工作流程，AWS 建議先分類文件，再選擇相應的 adapter。文章指出，每次 AnalyzeDocument API 呼叫、每頁及每種功能類型只能使用一個 adapter；其範例以文件中的文字標記辨識版本，再從 AWS Systems Manager Parameter Store 讀取 adapter ID。更新 Parameter Store 中的參照，可在不重新部署應用程式的情況下更新正式環境所用的 adapter。
安全部分則涵蓋 VPC endpoints、加密與最小權限 IAM。整體而言，這篇指南把 adapter 的部署、升級、文件分流及防護措施放進同一套營運流程，並特別提醒跨帳戶複製時，查詢與訓練資料必須另行管理。
為什麼值得注意
Custom Queries adapters 不只涉及模型訓練，也需要管理跨帳戶推進、表單版本分流與安全設定。AWS 的指南點出跨帳戶複製不會帶走查詢定義或訓練資料，這是規劃發布流程及配置保存方式時的重要限制。
