Service-Oriented Architecture (SOA) is becoming a key aspect for rapidly
evolving businesses that require agile system composability and
flexibility. As core concepts of any SOA-based system, services have
recently received significant interest. They can be used to support
Business-to-Business (B2B), Enterprise Application Integration (EAI),
and collaborations within or between Virtual Organizations. Like other
software components services expose both functional properties (i.e.
what they do) and non-functional properties (i.e. the way they are
supplied). Non-functional properties (NFPs) of a system are many and
varied, including all properties, which are not directly related to the
functionality provided. NFPs include quality of service (QoS) as well as
other properties such as cost, adherence to standards and obligations on
the consumer/provider. QoS is one of the most important subsets of
non-functional properties. Although the term QoS is traditionally used
to refer specifically to network performance and reliability
characteristics (and methods of guaranteeing these properties) in the
context of SOA the term must refer to a wider variety of service
properties. This is because there are numerous properties which can be
used as indicators of quality (including, e.g. performance,
dependability, security, accuracy, customer service, trust, etc.). The
term, as applied in SOA, must also refer to properties of system
components at different levels of granularity (e.g. network, server,
service, operation).

Non-functional properties play an important role in all service related
tasks in the service lifecycle, including discovery, selection and
operation of services. On one hand, the customer wants to differentiate
the services based on their non-functional properties given similar
functionalities provided. The service provider, on the other hand, needs
to optimize its service landscapes with respect to the non-functional
properties to stay competitive. Therefore, modeling, provisioning and
managing service related tasks such as discovery, composition,
negotiation and monitoring based on NFPs become fundamental challenges
in Service-Oriented Architectures with real business settings. Directly
connected to the tasks mentioned above are the specification,
enforcement and management of Service Level Agreements (SLAs). SLAs give
the service consumer some level of guarantee that the services provided
by the provider will operate within acceptable bounds, particularly
regarding the non-functional properties and QoS attributes. At the same
time SLAs serve a role for the provider in resource capacity planning
and avoiding unexpected legal wrangles. With the ever-growing demand for
eBusiness, service providers are increasingly interested in enforcing
contracts electronically allowing autonomous supervision of service
status and management. Machine-understandable NFPs and QoS models are
therefore key to the widespread uptake of SLAs as well as all of the
service related tasks mentioned above.

The workshop aims to tackle the research problems around models,
concepts, languages and methodologies that enable the specifications of
non-functional properties and Service Level Agreements in the context of
Service Oriented Computing. This edition aims also at providing a forum
to address the main challenges of bringing transparent, multi-level, and
holistic NFP and SLA management into service oriented systems. Such an
effort naturally requires a multi-domain and multi-disciplinary
approach, for instance, service-oriented architectures, model-driven
development, software engineering, performance management, and
enterprise computing. This enlarged view over the NFP and SLA topics is
reflected in the new workshop title including Management.

The first edition of the workshop was organized at the ICSOC 2007,
followed by the second edition at ECOWS 2008. The workshops constitute a
series of successful forums, each with more than 30 participants and 12
paper presentations.


The following indicates the general focus of the workshop. However,
related contributions are welcome as well.

* Languages for describing NFP attributes and offers.
* NFP modeling, description, and annotation.
* NFP-based discovery, selection, and ranking of Web Services.
* NFP-based negotiation, mediation, and agreement of service contracts.   
* Formal methods for NFP and Quality of Services.
* Quality metrics, KPIs, and requirement for services.
* NFP and SLA driven services composition and selection.
* NFP-based monitoring, accounting and recovery.
* Business requirements for electronic contracts.
* Legal status and requirements on SLAs.
* Cost and economic models for SLAs.
* Security and trust aspects in SLAs.
* Specification and modeling of Service Level Agreements in
service-oriented systems
* Methodologies and techniques for translation of hierarchical, and
multi-level SLAs.
* SLA requirements for Cloud computing and Software as a Service (SaaS).
* SLA negotiation and e-contracting.
* SLA-driven planning and provisioning in service-oriented systems.
* Optimization methodologies and techniques for SLA management.
* SLA monitoring, reporting, and compliance.
* SLA lifecycle management.   
* Event correlation, analytics, root cause analysis.
* Prediction models for non-functional properties, especially statistics
and machine learning techniques.
* SLA-driven adjustment, autonomic management at run time.
* Techniques and approaches of SLA-aware resource management, including
virtualized infrastructures.
* The relationship of SLAs and IT operational policies.
* Models, frameworks, and tools to support holistic SLA management.
