Variability Modeling for Service Oriented Product Line Architectures

Service Oriented Architecture (SOA) has emerged as a model for distributed computing that promotes flexible deployment and reuse. Software product lines (SPL) promote reusable development for product families. SOA systems need the capability of managing variability to address different client requirements. Our approach uses SPL concepts to model SOA systems as service families. SPL development relies on feature models to describe the commonality and variability of member applications. We introduce a multiple view SOA variability model based on feature modeling, which is described in UML and SoaML, the newly released SOA standard. Such a framework facilitates variability modeling of service families in a systematic and platform independent way.
