Key AWS services

Use Amazon CloudWatch to monitor runtime metrics and support reliability. Other services and features that support the three areas of reliability are as follows:

Foundations: AWS IoT Core enables you to scale your IoT application without having to manage the underlying infrastructure. You can scale AWS IoT Core by requesting account level limit increases.

Change management: AWS IoT Device Management enables you to update devices in the field while using Amazon S3 to version firmware, software, and update manifests for devices. AWS CloudFormation lets you document your IoT infrastructure as code and provision cloud resources using a CloudFormation template.

Failure management: Amazon S3 allows you to durably archive telemetry from devices. The AWS IoT rules engine Error action enables you to fall back to other AWS services when a primary AWS service is returning errors.

Resilience at the edge: AWS IoT Greengrass offers several features to help support data resiliency and backup needs with features which allow devices to communicate over the local network even after loss in internet connectivity, allowing the core to receive messages sent while the core is offline and using stream manager to process data locally until the connection is restored and send data to cloud or local storage destinations.
