Ingestion Layer

A key business driver for IoT is the ability to aggregate all the disparate data streams created by your devices and transmit the data to your IoT application in a secure and reliable manner. The ingestion layer plays a key role in collecting device data while decoupling the flow of data with the communication between devices.

With AWS IoT rules engine, you can build IoT applications such that your devices can interact with AWS services. AWS IoT rules are analyzed and actions are performed based on the MQTT topic stream a message is received on. 

Amazon Kinesis is a managed service for streaming data, enabling you to get timely insights and react quickly to new information from IoT devices. Amazon Kinesis integrates directly with the AWS IoT rules engine, creating a seamless way of bridging from a lightweight device protocol of a device using MQTT with your internal IoT applications that use other protocols.

Similar to Kinesis, Amazon Simple Queue Service (Amazon SQS) should be used in your IoT application to decouple the communication layer from your application layer. Amazon SQS enables an event-driven, scalable ingestion queue when your application needs to process IoT applications once where message order is not required.
