Building an IoT solution to securely transmit MQTT messages under private networks

This article discusses how to build an IoT solution on AWS using private networks to securely transmit MQTT messages between IoT devices, AWS services, and data consumers across different AWS accounts.

Specifically, the article covers:

• Overview of the solution architecture using AWS services like Direct Connect, Transit Gateway, PrivateLink, VPC endpoints, and Route 53 private hosted zones
• How to configure private DNS names for VPC endpoints using Route 53
• Setting up AWS IoT data interface endpoint in a VPC
• Using PrivateLink endpoint service and Network Load Balancer to share AWS IoT Core data endpoint across accounts
• Benefits of using private networks for IoT data transmission, such as enhanced security, data privacy, and regulatory compliance
