What’s your preferred platform?
Yes, but mostly for multi-process embedded Pi applications. Not so much cloud stuff.
I mean you can do Docker in the cloud, but tend to just use lambdas because it’s easier. When you’re dealing with IoT, how you route the MQTT messages into your Docker infrastructure in the cloud and all that begins to be a complicated question.
Whereas if you use serverless Lambdas it is really much easier. So unless I have a need to mess with Docker in the cloud, I tend not. How the data flows through the cloud with Docker tends to be hard to break out without going insane with message queues or something similar.
