The following table descrives how Amazon SNS integrates with Amazon IoT services, such as Amazon IoT Core, Amazon IoT Device Defender, Amazon IoT Events, and Amazon IoT Greengrass, to provide notifications for IoT events and alerts. 

These integrations allow you to effectively monitor device behavior, receive alerts for abnormal activities, and manage IoT devices with real-time updates and actions.


| Amazon Web Services service | Benefit of using with Amazon SNS | 
| --- | --- | 
| [Amazon IoT Core](https://docs.amazonaws.cn/iot/latest/developerguide/what-is-aws-iot.html) – Provides the cloud services that connect your IoT devices to other devices and Amazon Web Services Cloud services. | Receive notifications of Amazon IoT Core events. For more information, see [Creating an Amazon SNS rule](https://docs.amazonaws.cn/iot/latest/developerguide/iot-sns-rule.html) in the *Amazon IoT Developer Guide*. | 
| [Amazon IoT Device Defender](https://docs.amazonaws.cn/iot/latest/developerguide/device-defender.html) – Allows you to audit the configuration of your devices, monitor connected devices to detect abnormal behavior, and mitigate security risks. | Receive alarms when a device violates a behavior. For more information, see [How to use Amazon IoT Device Defender detect](https://docs.amazonaws.cn/iot/latest/developerguide/detect-HowToHowTo.html) in the *Amazon IoT Developer Guide*. | 
| [Amazon IoT Events](https://docs.amazonaws.cn/iotevents/latest/developerguide/what-is-iotevents.html) – Lets you monitor your equipment or device fleets for failures or changes in operation, and trigger actions when such events occur. | Receive notifications of Amazon IoT Events events. For more information, see [Amazon Simple Notification Service](https://docs.amazonaws.cn/iotevents/latest/developerguide/iotevents-other-aws-services.html#iotevents-sns) in the *Amazon IoT Events Developer Guide*. | 
| [Amazon IoT Greengrass](https://docs.amazonaws.cn/greengrass/v1/developerguide/what-is-iot-greengrass.html) – Extends Amazon onto physical devices so they can act locally on the data they generate, while still using the cloud for management, analytics, and durable storage. | Receive notifications of Amazon IoT Greengrass events. For more information, see [SNS connector](https://docs.amazonaws.cn/greengrass/v1/developerguide/sns-connector.html) in the *Amazon IoT Greengrass Version 1 Developer Guide*. |
