Abstract:
High availability is an increasingly important desideratum in software systems. However, as physical environments change, systems have to adapt to such changes. Dynamic reconfiguration refers to changing, updating, or otherwise modifying a system during execution. In order to provide high availability guarantees in the presence of evolving environments, software systems must include support for dynamic reconfiguration.

This presentation focuses on a methodology for building dynamically reconfigurable software using a mode of reconfiguration known as dynamic module replacement. The methodology is defined in the form of a design pattern, called the Service Facility Pattern, which is immediately applicable in popular technologies such as Java and .NET. The presentation will also include details of how the key ideas of this methodology can be used in the construction of dynamically reconfigurable product families that vary along non-functional dimensions. (e.g. security, performance,
fault-tolerance)
