Designing application and middleware software to run in concurrent and networked environments is a significant challenge facing software developers. This document presents an overview of the contents in the book Pattern-Oriented Software Architecture: Patterns for Concurrent and Networked Objects (POSA2) that address this challenge. The patterns in POSA2 form the basis of a pattern language that addresses issues associated with concurrency and networking. The book presents 17 interrelated patterns: Wrapper Facade, Acceptor-Connector, Extension Interface, Interceptor, Component Configurator, Reactor, Proactor, Asynchronous Completion Token, Scoped Locking, Strategized Locking, Thread-Safe Interface, Double-Checked Locking Optimization, Active Object, Monitor Object, Leader/Followers, Half-Sync/Half-Async, and Thread-Specific Storage. This material represents a range of patterns from idioms to architecture designs. The patterns cover core elements of building concurrent and networked systems: service access and configuration, event handling, synchronization, and concurrency. All patterns present extensive examples and the pattern known uses are presented in various programming languages, including C++, C, and Java.

The book can be used to tackle specific software development problems or read from cover to cover to provide a fundamental understanding of the best practices for constructing concurrent and networked applications and middleware.
