Objectives
The objective of this chapter is to introduce distributed systems
engineering and distributed systems architectures. When you have
read this chapter, you will:
■ know the key issues that have to be considered when designing
and implementing distributed software systems;
■ understand the client–server computing model and the layered
architecture of client–server systems;
■ have been introduced to commonly used patterns for distributed
systems architectures and know the types of system for which
each architectural pattern is applicable;
■ understand the notion of software as a service, providing webbased
access to remotely deployed application systems.
