Implement a failover strategy for your AWS IoT devices with the Disaster Recovery for AWS IoT solution

AWS Solution Implementation Guide

Publication date: May 2021

The Disaster Recovery for AWS IoT solution provides a failover strategy for your AWS IoT devices. Customers with critical AWS IoT Core workloads can use this solution to store and process their data in a secondary AWS Region if the primary Region is not accessible by their devices.

This solution provides the following key features:

1. Replicates classic device shadows and registry settings by configuring a global Amazon DynamoDB table in the primary and secondary Regions.

2. Implements active-passive disaster recovery and provides tools to copy existing IoT devices from your primary Region (active) to your secondary Region (passive).

3. Uses Amazon Route 53 with health checks and traffic policies to direct traffic from primary to secondary Region in case of Region failover.

This implementation guide provides infrastructure and configuration information for planning and deploying the AWS Disaster Recovery for AWS IoT in the Amazon Web Services (AWS) Cloud. This guide assumes that all devices will be created and provisioned in the primary Region and includes links to AWS CloudFormation templates that launch and configure the AWS services required to deploy this solution using AWS best practices for security and availability.

The guide is intended for IT infrastructure architects, administrators, and DevOps professionals who have practical experience with IoT solutions in the AWS Cloud with emphasis on AWS IoT Core, AWS IoT Device Management, Amazon DynamoDB, AWS Lambda, and AWS Step Functions.
