Use AWS IoT device shadows to improve app-device communication

July 10, 2019 / Stephen J. Bigelow

IoT applications rely on vast arrays of intelligent, networked devices, but this makes them vulnerable to availability and connectivity challenges. Applications need a stable network to communicate with IoT devices in real time. Otherwise, devices can disconnect or be overwhelmed with requests from multiple applications. This can lead to synchronization and status issues that can impair IoT data collection and usage.The AWS IoT Device Shadow service is designed to address these connectivity and synchronization challenges by acting as a communication link between applications and IoT devices. Let’s take a closer look at the service and consider how it can enhance an organization's IoT applications on AWS.
