ZeroMQ (eBook, PDF)

Messaging for Many Applications

• Format: PDF

Produktbeschreibung

Dive into MQ (aka ZeroMQ), the smart socket library that gives you fast, easy, message-based concurrency for your applications. With this quick-paced guide, youll 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.MQ maintainer Pieter Hintjens takes you on a tour of real-world applications, using extended examples in C to help you work with MQs API, sockets, and patterns. Learn how to use specific MQ programming techniques, build multithreaded applications, and create your own messaging architectures. Youll discover how MQ works with several programming languages and most operating systemswith little or no cost.Learn MQs main patterns: request-reply, publish-subscribe, and pipelineWork with MQ sockets and patterns by building several small applicationsExplore advanced uses of MQs request-reply pattern through working examplesBuild reliable request-reply patterns that keep working when code or hardware failsExtend MQs core pub-sub patterns for performance, reliability, state distribution, and monitoringLearn techniques for building a distributed architecture with MQDiscover whats required to build a general-purpose framework for distributed applications

Autorenporträt

Pieter Hintjens started his first business making video games 30 yearsago and has been building software products since then. Taking as hisprinciple, "the real physics of software is the physics of people", hefocuses now on building communities through "Social Architecture",writing, and helping others use ZeroMQ profitably. For two years he was president of the FFII, a large NGO fightingsoftware patents. He was CEO of Wikidot, founder of the EuropeanPatent Conference, and founder of the Digital Standards Organization. Pieter speaks English, French, Dutch, and bits and pieces of a dozenother languages. He plays with a West African drum group in Brusselsand is becoming a licensed NRA pistol instructor in Texas. Pieterlives with his beautiful wife and three lovely children in Brussels,Belgium and travels extensively.
