Software Pipelines presents an easy to use approach for scaling service-oriented business applications, abstracting away the complexities of low-level multi-threaded code. You can use "pipelines" to scale applications on a single multi-core server, or across many servers -- all transparent to the business application developer.
Here is a quote from the Preface of the book:
"Software Pipelines architecture is a new architecture that speciﬁ cally
addresses the problem of using parallel processing in the multicore era. It is a
new approach to the problem. Pipeline technology abstracts the complexities of
parallel computing and makes it possible to use the power of the new CPUs for
We wrote this book primarily for software architects, application developers,
and application development managers who need high-performance, scalable
business applications. Project managers, software quality assurance specialists,
and IT operations managers will also ﬁ nd it useful; however, the main focus is
software development. Our intention was to make the book as applicable as pos-
sible, and to provide tools that you can quickly learn and apply to your own
development challenges. "
So if you have the need to scale your applications in a flexible manner, and you are concerned with business transaction functionality, then I believe it should be very helpful to you. The concepts are broadly applicable, and can be applied to large-scale applications (or smaller ones that you expect will grow over time).
In nutshell, it is a bus...i mean Enterprise Service Bus. Where messages should be posted to this bus and interested parties subscribe themselves to this bus (a.k.a pipeline) and consume the messages. Am I correct?
