Dive into ØMQ (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. ØMQ maintainer Pieter Hintjens takes you on a tour of real-world applications, using extended examples in C to help you work with ØMQ’s API, sockets, and patterns. Learn how to use specific ØMQ programming techniques, build multithreaded applications, and create your own messaging architectures. You’ll discover how ØMQ works with several programming languages and most operating systems—with little or no cost. Learn ØMQ’s main patterns: request-reply, publish-subscribe, and pipeline Work with ØMQ sockets and patterns by building several small applications Explore advanced uses of ØMQ’s request-reply pattern through working examples Build reliable request-reply patterns that keep working when code or hardware fails Extend ØMQ’s core pub-sub patterns for performance, reliability, state distribution, and monitoring Learn techniques for building a distributed architecture with ØMQ Discover what’s required to build a general-purpose framework for distributed applications

"Even connecting a few programs across a few sockets is plain nasty when you start to handle real life situations. Trillions? The cost would be unimaginable. Connecting computers is so difficult that software and services to do this is a multi-billion dollar business. So today we're still connecting applications using raw UDP and TCP, proprietary protocols, HTTP, Websockets. It remains painful, slow, hard to scale, and essentially centralized. To fix the world, we needed to do two things. One, to solve the general problem of "how to connect any code to any code, anywhere." Two, to wrap that up in the simplest possible building blocks that people could understand and use easily. It sounds ridiculously simple. And maybe it is. That's kind of the whole point." If you are a programmer and you aim to build large systems, in any language, then Code Connected is essential reading. Code Connected Volume 1 takes you through learning ZeroMQ, step-by-step, with over 80 examples. You will learn the basics, the API, the different socket types and how they work, reliability, and a host of patterns you can use in your applications. This is the Professional Edition for C/C++.

Thirty-five years I've written code, a necromancer weaving spells to bring the dead to life. Hardware and electronics never held any charm for me. I've no love for chips and cables and solder. Give me a keyboard, a screen, and a language, and you have my attention. Thirty-five years produced a lot of work. So I thought, maybe time to talk about some of those projects.

Annotation Over the past 10 years, distributed systems have become more fine-grained. From the large multi-million line long monolithic applications, we are now seeing the benefits of smaller self-contained services. Rather than heavy-weight, hard to change Service Oriented Architectures, we are now seeing systems consisting of collaborating microservices. Easier to change, deploy, and if required retire, organizations which are in the right position to take advantage of them are yielding significant benefits. This book takes an holistic view of the things you need to be cognizant of in order to pull this off. It covers just enough understanding of technology, architecture, operations and organization to show you how to move towards finer-grained systems.
