Bastion Server（堡壘機）是一台位於 public subnet 中的 EC2 Instance，通常用於提供對 private subnet 內的資源提供安全遠端訪問權限。它擔任了進入 private 網路的入口，用於管理和維護內部資源，如資料庫服務器、應用服務器等。
NAT (Network Address Translation) Server 也是一台位於 public subnet 中的 EC2 Instance，用於允許 private subnet 中的資源提供訪問 Internet 的服務。它擔任了 outbound 流量的代理，將 private subnet 內資源的網路請求轉發到 Internet，並維護反應的網路連接狀態。
本篇是實作於 AWS 服務需要建立的這兩個 EC2 instances 之 Terraform 模組，完整的專案程式碼分享在我的 Github 上。
