RPC - Part: Transport Mechanism / Message Queues
More like Client-server Protocols
Stomp is simpler than 0mq, but you have a central server instead of point to point.
RestMQ - Redis based message queue RestMQ is a message queue which uses HTTP as transport, JSON to format a minimalist protocol and is organized as REST resources.
ZeroMQ / 0MQ
ØMQ is really just a networking library. Sockets the way you want them to work. Typically it’s for inter-application messaging and communication
Implements no security at all. Assumes you are on a private network.
http://techno-weenie.net/2011/5/22/zeromq-basics/ :: ZeroMQ Basics | techno weenie The name “ZeroMQ” was a little misleading for me. I think that’s because most other message queues are very similar: something pushes messages into a big, centralized queue, and workers pop messages off the front.

Mongrel2, a web server on ZeroMQ
Mongrel2 is a web server that uses ZeroMQ to talk to backend handlers written in any language.

Scalable and blazing-fast task queue built on Node.js and ZeroMQ. https://github.com/nullobject/bokeh :: nullobject/bokeh It allows you to offload tasks from your main application process and distribute them among a pool of workers. Workers can be running on the same host as your application, or scaled out onto multiple machines for greater processing power.

Super sockets are not meant to combat zeromq nor provide feature parity, but provide a nice solution when you don’t need the insane nanosecond latency or language interoperability that zeromq provides as super sockets do not rely on any third-party compiled libraries.

ZeroMQ + Apache Zookeeper for service discovery
Storm Cluster Uses the same combination (check the implementation). They use Apache Zookeeper (for service discovery) + 0MQ as transport.
Since Storm topologies are just Thrift structures, and Nimbus is a Thrift daemon, you can create and submit topologies in any language. Apache Thrift It is used as a remote procedure call (RPC) framework. Thrift is both cross-platform and more lightweight than REST for many operations.
About building RPC from 0MQ:
Basically, RPC is the REQ/REP pattern. What you are missing for full-blown RPC solution is:
Serialization – this is delberately decoupled from 0MQ. As a consequence you can use any serialisation library you like.
Resending of the request is case the server dies. This should be and will be done inside of 0MQ, but is not done yet. However, it can be easily emulated on top of it.
Anything I’ve missed? x
RabbitMQ is another alternative. You can build RPC for almost any programming language, even PHP.
And since node.js has an AMQP client, we can easily hook it up with RabbitMQ (RabbitMQ » Blog Archive » rabbitmq + node.js = rabbit.js - Messaging that just works) RabbitMQ » Blog Archive » rabbitmq + node.js = rabbit.js - Messaging that just works
