[Alibaba Cloud] [IoT Platform] [Adjustment of AMQP/HTTP2 server subscription billing mode for the public instance]
Changes : IoT platform plans to adjust the AMQP/HTTP2 server subscription billing mode of the public instance. If you do not use AMQP/HTTP2 server subscription, the adjustment will not have any impact on you. When the device sends a message to the platform before the adjustment, if the message is transferred to your business system by the platform through the server subscription method, the billing is only counted as one message. After adjustment, there are two messages, one from the device to the platform and one from the platform to your business system. If you have any questions, you can contact us at any time through the work order or service hotline.
