Today, AWS announced the general availability of a new feature of AWS IoT Core that simplifies the registration of certificate authorities (CAs) necessary for device provisioning and makes it easier to move devices between customers’ multiple AWS accounts within the same AWS region and between different regions. This reduces the complexity of registering devices to AWS IoT Core and helps customers accelerate the development lifecycle for their IoT implementations when using AWS IoT Core Just-in-Time Provisioning (JITP) and Just-in-Time Registration (JITR) device provisioning methods of AWS IoT Core.
