CLOSER is sponsored by INSTICC – Institute for Systems and Technologies of Information, Control and Communication
Scope

The 2nd International Conference on Cloud Computing and Services Science, CLOSER 2012, focuses on the emerging area of Cloud Computing, inspired by some latest advances that concern the infrastructure, operations, and available services through the global network. Further, the conference considers as essential the link to Services Science, acknowledging the service-orientation in most current IT-driven collaborations. The conference is nevertheless not about the union of these two (already broad) fields, but about Cloud Computing where we are also interested in how Services Science can provide theory, methods and techniques to design, analyze, manage, market etc. Cloud Computing.

Emerging Enterprise Technologies are profoundly changing the way we think of IT - from economics and efficiency to process and usage models. Many organizations look to the “externalized” IT systems and services as a potential cost-savings advantage by moving internally hosted IT services to external providers. Other organizations view the “external” IT as potential disaster recovery systems or as on-demand capacity to boost business continuity and customer service levels. We need to take a closer look, discerning what emerging enterprise technologies are and how they can catalyze creativity and produce a competitive advantage. There is hence a new wave of interest in 'Externalization of IT' - anything as a service (including Software as a Service, Infrastructure as a Service, Platform as a Service), On Demand delivery, outsourcing, and so on. This emerging facilitation and way of utilizing services through IT is what we are referring to as Cloud Computing.

The four perspectives in which we are addressing the area of Cloud Computing in this conference are: (i) Fundamentals of Cloud Computing; (ii) Services Science foundations for Cloud Computing; (iii) Cloud Computing platforms and applications; (iv) Cloud Computing enabling technology.

Paper Submission

Authors should submit an original paper in English, carefully checked for correct grammar and spelling, using the on-line submission procedure. The initial submission must have between 3 to 13 pages otherwise it will be rejected without review. Please check the paper formats page so you may be aware of the accepted paper page limits.
The guidelines for paper formatting provided at the conference web ought to be used for all submitted papers. The preferred submission format is the same as the camera-ready format. Please check and carefully follow the instructions and templates provided. Each paper should clearly indicate the nature of its technical/scientific contribution, and the problems, domains or environments to which it is applicable.

Papers that are out of the conference scope or contain any form of plagiarism will be rejected without reviews. Please read INSTICC's ethical norms regarding plagiarism and self-plagiarism.

Remarks about the on-line submission procedure:
1. A "double-blind" paper evaluation method will be used. To facilitate that, the authors are kindly requested to produce and provide the paper, WITHOUT any reference to any of the authors. This means that is necessary to remove the authors personal details, the acknowledgements section and any reference that may disclose the authors identity.
LaTeX/PS/PDF/DOC/DOCX/RTF format are accepted.
2. The web submission procedure automatically sends an acknowledgement, by e-mail, to the contact author.

Paper submission types:
Regular Paper Submission
A regular paper presents a work where the research is completed or almost finished. It does not necessary means that the acceptance is as a full paper. It may be accepted as a "full paper" (30 min. oral presentation) , a "short paper" (20 min. oral presentation) or a "poster".

Position Paper Submission
A position paper presents an arguable opinion about an issue. The goal of a position paper is to convince the audience that your opinion is valid and worth listening to, without the need to present completed research work and/or validated results. It is, nevertheless, important to support your argument with evidence to ensure the validity of your claims. A position paper may be a short report and discussion of ideas, facts, situations, methods, procedures or results of scientific research (bibliographic, experimental, theoretical, or other) focused on one of the conference topic areas. The acceptance of a position paper is restricted to the categories of "short paper" or "poster", i.e. a position paper is not a candidate to acceptance as "full paper".

Camera-ready:
After the reviewing process is completed, the contact author (the author who submits the paper) of each paper will be notified of the result, by e-mail. The authors are required to follow the reviews in order to improve their paper before the camera-ready submission.

Publications

All accepted papers (full, short and posters) will be published in the conference proceedings, under an ISBN reference, on paper and on CD-ROM support.
All papers presented at the conference venue will be available at the SciTePress Digital Library (http://www.scitepress.org/DigitalLibrary/).
SciTePress is member of CrossRef (http://www.crossref.org/).
A short list of presented papers will be selected so that revised and extended versions of these papers will be published by Springer-Verlag in a SSRI Series book.
A short list of papers presented will be selected for publication of extended and revised versions in a special issue of Cluster Computing.
The proceedings will be submitted for indexation by Thomson Reuters Conference Proceedings Citation Index (ISI), INSPEC, DBLP and EI (Elsevier Index).

Venue

Overlooking the Douro River, Porto is one of the most ancient European cities, It was born and developed from the northern bank of this river during the Middle Ages. One of the most significant aspects of Porto and its historical centre is its landscape, combining harmony with the urban structure and presenting a frame of rare beauty. The city was classified as World Heritage by UNESCO in 1996. When discovering Porto, you will find many surprises. Besides its welcoming and conservative environment, Porto is also contemporary and artistic. This is shown not only in the streets, architecture, monuments and museums but also in the terraces, restaurants and leisure and shopping areas.
