ZeroMQ is a messaging library which lets you write scalable and performant distributed software. Or, as some say, sockets on steroids.

ZeroMQ has quite a misleading name. It is not really a classic message queuing solution at all - it is a messaging library which simplifies the task of writing high-performance and scalable distributed applications.

ZeroMQ abstracts the standard sockets and provides building blocks for almost any distributed scenario and topology: from classic publish-subscribe pattern between independent services to cross-thread communication inside a process, while introducing a very low overhead, compared to alternatives. It integrates well with whole range of technologies from Python and Ruby, over Java and C# to C++ and Go.

This talk will discuss various distributed/concurrent scenarios and show how ZeroMQ helps to implement appropriate solutions. Of course, the pitfalls and limitations will be discussed, too.
