Software reuse has been one of the most effective paradigms for building software systems and applications for decades. Recently, the rapid and fundamental advances in computing technologies have been driving the role and scope of software systems to new levels. A number of new types of software systems are emerging, among which service based systems, pervasive computing, cloud computing and Internet of Things are eminent examples. The advent of these emerging systems has raised the level of software reuse to services, large-scale components or agglomeration of components in more challenging context which is pervasive, service-oriented, embedded real-time, trustworthy, or in very large corporation scale or in new application domains such as Big Data. Systematic and large-scale reuse of reusable assets at multiple development levels is improving the efficiency of software development activities significantly in terms of cost and time. However, previous research in software reuse mainly focused on the functional aspect of a system, tended to ignore or treat the quality aspects trivially. Modern computing models tend to be globally distributed, ubiquitous, highly trustworthy, and dynamically adaptive. These systems, such as SOA, pervasive/ubiquitous systems, and embedded systems, have imposed more rigorous quality requirements on software reuse technologies. In the "cloud era" nowadays, it becomes a great challenge to meet the new requirements of emerging software systems and meanwhile enjoy the benefits of substantial software reuse. Recently, the research community and industry have been aware of the above weakness and much work has been ongoing. In this workshop we wish to bring together researchers and practitioners to share latest research results, advances and practical experiences under the banner of "Quality Oriented Reuse of Software for Emerging Software Systems in Cloud Era". The workshop will act as a forum for active discussion, idea stimulation and communication.
