题意：AWS IoT 中设备网关和 MQTT 代理的区别
问题背景：
I'm studying AWS IoT architecture and I don't understand if there are differences between device gateway and mqtt broker. It seems that in AWS IoT architecture, functions of mqtt broker are performed by the device gateway. Is it right?
我正在学习 AWS IoT 架构，但不明白设备网关和 MQTT 代理之间是否有区别。在 AWS IoT 架构中，似乎 MQTT 代理的功能是由设备网关执行的。这样理解对吗？
问题解决：
Yes, it seems the same to me. Apparently, they are talking about "Gateway to the cloud" which is different from the usual IoT terminology for gateway which connects sensors to the interent and works as a producer of messages.
是的，我也觉得它们是一样的。显然，他们在说“通向云的网关”&
