CLOUD SERVICE BROKERAGE - TOWARDS THE MULTI-CLOUD ECOSYSTEM
===========================================================

The 2nd International Workshop on Cloud Service Brokerage (CSB 2014).

Co-located with the 3rd European Conference on Service-Oriented and
Cloud Computing (ESOCC 2014), Manchester, UK, 2-4 September, 2014.


CALL FOR PAPERS

The workshop series on Cloud Service Brokerage is the premier workshop
focusing on enabling technology for realising the multi-cloud ecosystem,
in which cloud service brokers will play a pivotal role in supporting
cloud service providers and consumers. CSB 2014 is the second workshop
in the series, co-hosted by the EU FP7 projects Broker@Cloud and PaaSage,
and will be held at ESOCC 2014 in Manchester. It focuses on enabling
technology for the multi-cloud ecosystem. The first CSB 2013 workshop
was held in conjunction with ICSOC 2013 in Berlin, and focused on
methods and mechanisms for cloud service brokerage.

BACKGROUND

This workshop looks to a future in which a multi-cloud ecosystem exists,
within which many cloud providers and consumers interact to create,
discover, negotiate and use software services. Supporting this ecosystem
are cloud brokers, whose role is to bring together providers and consumers,
by offering service portals with added value for all parties. A central
feature of the broker’s role will be to assist with software service
generation (from abstract models to platform-specific deployments),
multi-cloud translation (model-driven adaptation and deployment of services)
and assure quality control (governance; functional testing and monitoring),
service continuity (failure prevention and recovery; service substitution)
and market competition (arbitrage; service optimization; service
customization).

To promote the creation of this kind of ecosystem, it is necessary to
develop common standards, service models, methods and mechanisms that will
operate across a wide variety of platforms and infrastructure, and across
disparate service protocols, which currently include: WSDL/SOAP-based
services, RESTful services and Rich Client/AJAX applications.


TOPICS OF INTEREST

We solicit original research papers covering the following topics of
interest:

Abstract service models – current service description languages are only
up to the task of describing the service interface; what is needed are
abstract models to describe the complete behaviour and performance of
services, such that model-translation algorithms can generate equivalent
services on different platforms.

Model-driven generation – current software services are designed in
vendor-specific ways that prevent them being ported onto different platforms;
what is needed are sets of translation algorithms for converting abstract
service models into platform-specific applications, or sets of equivalent
applications deployed across multi-clouds.

Service behaviour certification – current quality control is mostly achieved
by in-house developer-based testing; what is needed is a means of determining
whether alternative services are equivalent, certified by generating standard
test sets from functional specifications of services, and grounding these for
each of the service protocol technologies described above;

Service performance monitoring – current service monitoring technology is
limited to SLAs for response-times and availability of end-points; what is
needed is a more sophisticated data fusion approach, such as complex event
processing, with trend prediction, supporting service optimisation and
substitution.

Service optimization – current service platforms offer single-vendor services
with failover substitution, or manual selection from several providers; what
is needed is a means of offering multi-vendor services on a competitive basis,
with automatic arbitrage between different providers, to support constrained
optimization of cloud performance.

Service governance – current services and platforms are developed following
in-house software processes; what is needed are explicit standards and methods
for governing the whole service lifecycle, ensuring common quality standards
and interfaces, supporting convergent service development and service
customisation.

This list is not exhaustive; other topics relevant to the Consumer, Provider
and Broker roles (NIST cloud role definitions) will be considered. Please
note that service security is out of scope, being a matter for the Auditor
role. Please note also that only design-time adaptation will be considered,
since another ESOCC workshop will be devoted to run-time adaptation issues.


IMPORTANT DATES

* Paper submission: (30 May) extended to 14 June 2014
* Reviews completed: (30 June) extended to 4 July 2014
* Camera-ready copy: 15 July 2014


SUBMISSION PROCESS

Authors are invited to submit original, previously unpublished research papers
written in English. We invite (i) full research papers up to 12 pages in
length; and (ii) short vision, or position papers up to 6 pages, both including
all references and figures, on a topic within the remit of the workshop.

All submissions must be prepared in the Springer LNCS format. The Springer
formatting guidelines are available at:

http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0

All submissions will be peer-reviewed by members of the international program
committee. Paper acceptance will be based on originality, significance,
technical soundness, and clarity of presentation. Please submit papers in PDF
via EasyChair, following instructions to be published on the CSB 2014 website:

http://csb2014.modelbased.net/

We anticipate a 50% acceptance rate after reviewing has been completed. Accepted
full papers will be allowed up to 15 pages; and short vision/position papers up
to 8 pages. At least one author of each accepted paper must register and
participate in the workshop. Please see details to be published on the ESOCC
website:

http://esocc2014.cs.manchester.ac.uk/

It is anticipated that publication will be in the Springer CCIS series
(Communications in Computer and Information Science), in proceedings shared
jointly with other ESOCC workshops and the PhD symposium.
