Abstract
Variability is the ability of a software system or artifact to be adapted for specific contexts, in a preplanned manner. Many of today's software systems are built with variability in mind, e.g., product lines and families, self-adaptive systems, open platforms, or service-based systems that support dynamic runtime composition of web services. Variability is reflected in and facilitated through the software architecture. Also, as the software architecture is a reference point for many development activities and for achieving quality attributes, variability should be treated as a first-class and cross-cutting concern in software architecture. Therefore, the Second International Workshop on Variability in Software Architecture (VARSA 2012) aims at identifying critical challenges and progressing the state-of-the-art on variability in software architecture. VARSA 2012 is a follow-up of the First International Workshop on Variability in Software Architecture (VARSA 2011), held at WICSA 2011.
