<p>A distributed system architecture comprises a network of computers and the
software components that execute on those computers. Such architectures are
commonly used to improve the performance, reliability, and reusability of
complex applications. Typically, there is no shared address space
available to remotely-located components (that is to say, components running
on different nodes of the network), and therefore these components must
communicate using some form of message-passing.
