A quick comparison of the most ubiquitous application in the universe between two popular IOT protocols. While I'm obviously biassed, the two code examples are devoid of any marketing/sales fluff and speak for themselves : )

1. “Hello World”
in
OMG-DDS
and
ZeroMQ

3. Application-managed IP-
addresses & port numbers
No type awareness
Strong coupling with remote
application.
Client-server architecture
Requires manual data
