# 에서 Lambda 함수 생성 AWS IoT Events
AWS IoT Events 는 경보가 이메일 및 SMS 알림을 보내고 받을 수 있도록 하는 Lambda 함수를 제공합니다.
## 요구 사항
경보용 Lambda 함수를 만들려면 다음 요구 사항이 적용됩니다.
+ 경보가 SMS 알림을 보내는 경우 Amazon SNS가 SMS 메시지를 전송하도록 구성되어 있는지 확인합니다.
+ 자세한 내용은 다음 설명서를 참조하세요.
+ [Amazon Simple Notification Service 개발자 안내서의 Amazon SNS를 사용한 모바일 문자 메시징](https://docs.aws.amazon.com/sns/latest/dg/sns-mobile-phone-number-as-subscriber.html) 및 [ Amazon SNS SMS 메시지의 발신 자격 증명](https://docs.aws.amazon.com/sns/latest/dg/channels-sms-originating-identities.html). **
+ *AWS SMS 사용 설명서*의 [AWS End User Messaging SMS란 무엇입니까?](https://docs.aws.amazon.com/sms-voice/latest/userguide/what-is-sms-mms.html)
+ 경보가 이메일 또는 SMS 알림을 보내는 경우에서 Amazon SES 및 Amazon SNS AWS Lambda 작업을 허용하는 IAM 역할이 있어야 합니다.
