Pattern-Oriented Software Architecture, Volume 3 - Patterns for Resource
Efficient management of resources is critical in the execution of any kind of software. From embedded software in a mobile device to software in a large enterprise server, it is important that resources, such as memory, threading, files, or network connections, are managed efficiently to allow the systems to function properly and effectively.
As the need for resource management
is often discovered late in the software development lifecycle, and changing the
system design at this late stage is difficult, it is important that such tasks
are performed early in the lifecycle. Since systems belonging to different
domains have different system constraints and requirements, a technique that
works well in a particular system or configuration might not be so effective in
POSA 3 uses patterns to present techniques for implementing effective resource management in a system. The patterns are covered in detail, making use of several examples, and, as in previous POSA volumes, directions are given on how to implement the presented patterns. Additionally, the volume presents a thorough introduction into resource management, and two case studies where the patterns are applied to the domains of ad hoc networking and mobile radio networks. The patterns are grouped by different areas of resource management and hence address the complete lifecycle of resources: resource acquisition, coordination and release.
