OpenMAMA

1 140 6.3 C++

OpenMAMA is an open source project that provides a high performance middleware agnostic messaging API that interfaces with a variety of proprietary and open source message oriented middleware systems. (by finos)

Unlikely, but they seem to be different things altogether. BlazingMQ appears to be a traditional message queue (think ActiveMQ), with message peristence. ZeroMQ is more of a network middleware (think Tibco Rendezvous), and does not include persistence.
BlazingMQ also appears to be more of a "platform" or "service" that an app can use (sort of like Oracle, say) -- ZeroMQ includes libraries that one can use to build an app, service or platform, but none is provided "out of the box".
Which makes it harder to get started with ZeroMQ, since by definition every ZeroMQ app is essentially built "from scratch".
If you're interested in ZeroMQ, you may want to check out OZ (https://github.com/nyfix/OZ), which is a Rendezvous-like platform that uses the OpenMAMA API (https://github.com/finos/OpenMAMA) and ZeroMQ (https://github.com/zeromq/libzmq) transport to provide a full-featured network middleware implementation. OZ has been used in our shop since 2020 handling approx 50MM high-value messages per day on our global FIX network.
