Pattern-Oriented Software Architecture Volume 3: Patterns for Resource Management

Efficient management of resources is critical in 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 chancing the system design at this stage is difficult, it is important that such tasks are performed early in the lifecycle. Since systems belonging to different domains have different constraints and requirements, a technique that works well in a particular system or configuration might not be effective in another.

'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 them. Additionally, the volume presents a thorough introduction to 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 address the complete lifecycle of resources: acquisition, management and release.
