 The key AWS feature supporting cost optimization is cost allocation tags, which help you to understand the costs of a system. The following services and features are important in the three areas of cost optimization: 
+  **Cost-effective resources**: [Amazon Kinesis](https://aws.amazon.com/kinesis/) and [Amazon S3](https://aws.amazon.com/s3/) are AWS services that enable you to process multiple IoT messages in a single request in order to improve the cost effectiveness of compute resources. 
+  **Managing demand and supplying resources**: [AWS IoT Core](https://aws.amazon.com/iot-core/) is a managed IoT service for managing connectivity, device security to the cloud, messaging routing, and device state. 
+  **Optimize over time**: The AWS IoT Blog section on the AWS website is a resource for learning about what is newly launched as part of AWS IoT.
