Від видавця

Dive into OMQ (aka ZeroMQ), the smart socket library that gives you fast, easy, message-based concurrency for your applications. With this quick-paced guide, you'll learn hands-on how to use this scalable, lightweight, and highly flexible networking tool for exchanging messages among clusters, the cloud, and other multi-system environments. OMQ maintainer Pieter Hintjens takes you on a tour of real-world applications, using extended examples in C to help you work with OMQ's API, sockets, and patterns. Learn how to use specific OMQ programming techniques, build multithreaded applications, and create your own messaging architectures. You'll discover how OMQ works with several programming languages and most operating systems with little or no cost. Learn OMQ's main patterns: request-reply, publish-subscribe, and pipeline Work with OMQ sockets and patterns by building several small applications Explore advanced uses of OMQ's request-reply pattern through working examples Build reliable request-reply patterns that keep working when code or hardware fails Extend OMQ's core pub-sub patterns for performance, reliability, state distribution and monitoring Learn techniques for building a distributed architecture with OMQ Discover what's required to build a general-purpose framework for distributed applications
