Module 6: Accessing other AWS services - AWS IoT Greengrass

AWS IoT Greengrass Version 1 no longer receives feature updates, and will receive only security patches and bug fixes until June 30, 2023. For more information, see the AWS IoT Greengrass V1 maintenance policy. We strongly recommend that you migrate to AWS IoT Greengrass Version 2, which adds significant new features and support for additional platforms.

Module 6: Accessing other AWS services

This advanced module shows you how AWS IoT Greengrass cores can interact with other AWS services in the cloud. It builds on the traffic light example from Module 5 and adds a Lambda function that processes shadow states and uploads a summary to an Amazon DynamoDB table.

                AWS IoT connected to an AWS IoT Greengrass core, which is connected to a light switch device
                    and a traffic light device shadow. The traffic light device shadow is connected
                    to a Lambda function, which is connected to a DynamoDB table.

Before you begin, run the Greengrass device setup script, or make sure that you have completed Module 1 and Module 2. You should also complete Module 5. You do not need other components or devices.

This module should take about 30 minutes to complete.


This module creates and updates a table in DynamoDB. Although most of the operations are small and fall within the Amazon Web Services Free Tier, performing some of the steps in this module might result in charges to your account. For information about pricing, see DynamoDB pricing documentation.
