Designing application and middleware software to run in concurrent and
networked environments is a significant challenge to software
developers.
The patterns catalogued in this second volume of Pattern-Oriented
Software Architecture (POSA) form the basis of a pattern language that
addresses issues associated with concurrency and networking.

The book presents 17 interrelated patterns ranging from idioms through
architectural designs. They cover core elements of building concurrent
and network systems: service access and configuration, event handling,
synchronization, and concurrency. All patterns present extensive
examples
and known uses in multiple 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.
