REST API によって実行されるステートレス呼び出しがクラウド アプリケーションで役立つのはなぜですか?
正解:D
Stateless calls made by REST APIs are advantageous in cloud applications because they don't retain user session information on the server. This means each call is independent and doesn't rely on information from previous calls, making the system more reliable and easier to scale horizontally. Stateless architecture allows for the redeployment of components without affecting the system's state or behavior, which is essential for cloud environments where resources need to be dynamically allocated and managed.
