Làm thế nào kết nối eWon Flexy và AWS IoT Core? How HMS Connects to AWS IoT Core?

Đối với eWon Flexy, có hai sự lựa chọn để kết nối với AWS IoT Core:

Flexy direct to AWS – MQTT

The MQTT connector in Flexy is used to create a certificate-based SSL connection with AWS IoT Core. Data from the asset is buffered locally in the Flexy gateway before being sent directly to the AWS IoT Core interface. This interface can be configured manually, or HMS Engineering services can be leveraged to create an automated device provisioning solution.

Talk2M RESTful API 

Talk2M offers two RESTful API interfaces. DMWeb API is designed to support historical logging of data. Data from the asset is buffered locally in the Flexy gateway before being sent to a buffer in Talk2M (data mailbox) where data can be stored for up to 10 days. A second REST interface on Talk2M M2Web API allows for real-time reads and writes to tags on any Flexy device. AWS Kinesis or an application like the Canary Historian or Ignition running on an AWS VM can read data from either REST API.
