Amazon Bedrock 試用心得 — 安全的在雲端上使用生成式 AI
這一兩年生成式 AI 開始起飛，雲端服務供應商也提供相關的 AI 服務，這次就來分享 Amazon Bedrock 開箱試用，很簡單的看看有什麼樣資訊安全相關功能吧！
Amazon Bedrock 介紹
依據官方文件介紹
Amazon Bedrock 是一項全受管服務，透過單一 API 以及建置生成式 AI 應用程式所需的各種廣泛功能，搭配安全、隱私與負責任的 AI，提供來自領先 AI 公司的各種高效能基礎模型 (FM) 選擇，例如 AI21 Labs、Anthropic、Cohere、Meta、Stability AI 和 Amazon。使用 Amazon Bedrock 時，您可以輕鬆實驗並評估您的使用案例適用的頂級 FM、使用微調和擷取增強產生 (RAG) 等技術私下加以自訂，以及建置使用您的企業系統和資料來源執行任務的代理程式。由於 Amazon Bedrock 是無伺服器的，因此您不必管理任何基礎設施，而且可以使用已熟悉的 AWS 服務，將生成式 AI 功能安全整合並部署至應用程式中。

進入後可以先到入門看概觀介紹
官方提供了範例供使用者參考，但我覺得普普通通
平台上列出了支援的模型與限制，並有對應適合的場景
使用模型
使用前需要請求模型存取權限，Amazon 自家的模型的不需要特別寫資料送給供應商，但時下最紅的 Claude 需要先送審
Claude3 要先填寫一些基本資料送出後方可使用

選取模型，這邊使用基本的 Amazon Titan Text G1 — Express
接著就會到使用畫面，可以做基本互動功能，同時提供多個使用範例
Amazon Titan 在目前的版本中有語言的限制，看起來還不正式支援中文
輸入看看我的需求，分別輸入中文跟英文看看
我想做一道 Gordon Ramsay 的 威靈頓牛排，但我是一個下廚白癡，請你告訴我所有細節與步驟，包含基本知識，內容越多越好
I am an absolute beginner in cooking and want to try making Gordon Ramsay’s Beef Wellington dish. Could you please provide me with a comprehensive, step-by-step guide on how to prepare it, including all the necessary ingredients, equipment, basic cooking techniques, and any important tips or tricks? The more detailed the instructions are, the better, as I need to learn from the very basics.

Instructions:
1. Preheat the oven to 425°F (220°C).
2. Trim the beef tenderloin of any excess fat and season it with salt and pepper on both sides.
3. Roll out the puff pastry on a lightly floured surface until it is about 1/8-inch thick.
4. Place the puff pastry on a baking sheet.
5. Spread the mushroom duxelle over the puff pastry, leaving a 1-inch border around the edges.
6. Place the beef tenderloin on top of the mushroom duxelle, leaving a 1-inch border around the edges.
7. Spread the béchamel sauce over the beef tenderloin, leaving a 1-inch border around the edges.
8. Fold the puff pastry edges over the beef tenderloin and mushroom duxelle, pressing them together to seal the edges.
9. Brush the egg white over the puff pastry surface to create a glossy glaze.
10. Cut a few slits on top of the puff pastry to allow steam to escape during baking.
11. Place the beef Wellington on a baking dish and bake in the preheated oven for 25–30 minutes, or until the puff pastry is golden brown and the beef is cooked to your desired temperature (for medium-rare, the internal temperature should be around 135°F (57°C)).
12. Remove the beef Wellington from the oven and let it rest for 10–15 minutes before serving.
13. While the beef Wellington is baking, prepare the béchamel sauce.
14. In a saucepan, melt the butter over medium heat.
15. Add the all-purpose flour and whisk until combined.
16. Slowly add the whole milk, whisking constantly to prevent lumps from forming.
17. Cook the mixture over medium heat, whisking constantly, until it thickens.
18. Add the garlic powder, onion powder, dried thyme, dried sage, salt, and ground black pepper.
19. Continue cooking the sauce over low heat until it reaches the desired consistency.
20. Once the beef Wellington is done resting, slice it into portions and serve with the béchamel sauce.
21. Garnish with chopped fresh parsley and enjoy!Tips and Tricks:
1. Use high-quality ingredients for the best flavor.
2. Allow the beef Wellington to rest before slicing to allow the juices to redistribute.
3. Be careful not to overcook the beef, as it can become dry.
4. The béchamel sauce can be made ahead of time and stored in the refrigerator until ready to use.
5. The puff pastry can be made ahead of time and frozen until ready to use.
6. The beef Wellington can be reheated in the oven before serving.
7. Experiment with different herbs and spices to add your own twist to the dish.By following these step-by-step instructions, you can create a delicious and impressive Beef Wellington that will impress your family and friends. Enjoy!
使用的模型會影響輸出，可以透過選擇不同模型來達到對應的需求
模型調用紀錄
有規模的企業通常會有使用量、資安或稽核上的考量，確保所有的模型使用都留有紀錄，這邊也提供選項能夠紀錄日誌調用，並可搭配 CloudWatch 監控
選取左方的設定即可看到帳戶層級的設定選項
輸入 S3 位置
產生的日誌紀錄會出現在你指定的 S3 位置

模型調用日誌記錄
模型叫用記錄 可用於收集叫用日誌、模型輸入資料，以及在 Amazon Bedck 中使用的所有叫 AWS 帳戶 用的模型輸出資料。預設會停用記錄。

Amazon Bedrock 濫用偵測
稍微看了一下官方文件，看起來輸入的資料會被 Amazon 的自動偵測機制分析，如果企業有高度機敏資料的考量，就要三思是否要使用 Bedrock
理想上應該先制定生成式 AI 的 安全政策與使用原則，不是只相信供應商或是技術控制部分
AWS PrivateLink
Bedrock 服務可以透過 PrivateLink 做傳輸，從架構安全上考量會建議走PrivateLink 更好
