The block diagram below gives an overview of the AWS IoT system. The goal is to integrate squid.Link gateway with AWS IoT Core to facilitate access to all connected devices underneath the gateway. - Page 10 Getting started AWS IoT Core Squid.Link Figure 6 AWS IoT Core system The state of each device connected to AWS IoT is stored in a device shadow. The Device Shadow service manages device shadows by responding to requests to retrieve or update device state data. The Device Shadow service makes it possible for devices to communicate with applications and for applications to communicate with devices.
