r/MQTT

Hi,

I am designing an architecture for an industrial project. Goal is to get data to the cloud, we have an industrial MQTT broker that we can use EMQX. The setting is as follows: hundreds of sites across the globle (potentially) Machines can expose data over OPC-UA, but this is the problem: There is no edge device to place a gateway on prem. Thinking on a piece of software that can read OPC-UA, from the cloud. I don’t know if this works, and how OPC-UA behaves over a WAN. Any opinion or insight is appreciated. I am looking for something commercial and reliable.

Looking at various options like HiveMQ, kepware edge, and just learned Litmus exists. What is the go to software for this? How is this usually done?
