FoSEC is the flagship workshop for software engineering for/in the cloud run within the IEEE World Congress on Services.  The workshop builds on the success of the previous versions and its special issue to the Journal of Systems on Software, featuring contributions from some of the top scholars in software engineering researchers and practitioners. Practitioners are very likely to beg, borrow and steal from software engineering in-the-small to benefit the case of software engineering for the ultra-large-scale, as it is the case of the cloud. Though the fundamentals of engineering software in both paradigms exhibit resemblance, software engineering for the cloud require novel approaches, which address the interplay between technical, economics-driven considerations and shifts software engineering towards a utility-based engineering for software-, infrastructure-, data storage and/or platform- as services. The goal of this workshop is to address these gaps by strengthening the cross-fertilization of advances from software engineering, services and cloud computing. The workshop will explore, debate and increase our understanding to the following: (i) how recent advances in software engineering (with an emphasis on software architectures, architecting dependable systems, self-adaptive software architectures, economics-driven software engineering, risk management, security software engineering, green software engineering and testing) can(not) relate to the case of cloud; (ii) what are the most recent innovations, trends, results, experiences and concerns in the field that appraise the paradigm-shift in engineering software systems as cloud services or cloud infrastructure; (iii) what are the open research directions for software engineering FOR the cloud?; (iv) how the paradigm will shape the future of engineering software IN the cloud i.e. benefiting from the cloud infrastructure, virtualization and economics of scale. The workshop thus aims to bridge the gap between software engineering, services, businesses and cloud computing communities by specifically addressing the challenges for software engineering FOR and IN the cloud.
