Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Quality attribute requirements play an important role in service selection in a service-oriented architecture environment. It is easy to envision finding several services that fulfill the functional requirements but fail to meet important quality attribute measures. Service level agreements provide the architect with a specification of the verifiable quality characteristics that the service will provide. Such a specification allows the architect to select the service that best supports the system's quality attribute requirements. This report surveys the state of practice in service level agreement specification and offers guidelines on how to assure that services are provided with high availability, security, performance, and other required qualities. In addition, this report discusses the quality properties that have been expressed in service level agreements, and it considers the mechanisms used to assure service quality by contract and those used by service providers to achieve and monitor quality properties. Also, this report examines the support for expressing service quality requirements in existing service technologies and describes areas where more research is needed."
Download or read book Grids and Service Oriented Architectures for Service Level Agreements written by Philipp Wieder and published by Springer Science & Business Media. This book was released on 2010-08-03 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Grids and service-oriented architectures have evolved to a common infrastructure for providing and consuming services in research and commercial environments, mechanisms are needed to agree on the objectives and the quality of such service provision. There is a clear trend to use electronic contracts between service consumers and one or more service providers, in order to achieve the necessary reliability and commitment from all parties. Service Level Agreements (SLAs) are the means to model and manage such contracts in a unified way. Grids and Service-Oriented Architectures for Service Level Agreements, the thirteenth volume of the CoreGRID series, contains current research and up-to date solutions from research and business communities presented at the IEEE Grid 2009 Workshop on Service Level Agreements in Grids, and the Service Level Agreements in Grids Dagstuhl Seminar 2009. The contributions in this volume cover Grid environments, but also generic models for SLA management that are applicable to service-oriented systems in general, like market-economic strategies, negotiation models, or monitoring infrastructures. Grids and Service-Oriented Architectures for Service Level Agreements is designed for a professional audience composed of researchers and practitioners within the Grid community industry, and is also suitable for advanced-level students in computer science.

Download or read book Organic Service Level Management in Service Oriented Environments written by Lei Liu and published by KIT Scientific Publishing. This book was released on 2014-08-25 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic service-oriented environments (SOEs) are characterised by a large number of heterogeneous service components that are expected to support the business as a whole. The present work provides a negotiation-based approach to facilitate automated and multi-level service-level management in an SOE, where each component autonomously arranges its contribution to the whole operational goals. Evaluation experiments have shown an increased responsiveness and stability of an SOE in case of changes.
Download or read book Service Level Management in Emerging Environments written by and published by John Wiley & Sons. This book was released on 2021-03-11 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networks are now embedded in daily life thanks to smaller, faster, inexpensive components that are more powerful and increasingly connected. Parallel to this quantitative explosion of communication networks, technology has become more complex. This development comes with challenges related to management and control, and it has become necessary to manage the service level demands of the client to which the service provider commits. Different approaches to managing one or more service level components in different emerging environments are explored, such as: the Internet of Things, the Cloud, smart grids, e-health, mesh networking, D2D (Device to Device), smart cities and even green networking. This book therefore allows for a better understanding of the important challenges and issues relating to Quality of Service (QoS) management, security and mobility in these types of environment.

Download or read book Improving Service Level Engineering written by Roland Schütze and published by Springer. This book was released on 2017-07-20 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines how fuzzy methods can be employed to manage service levels in business and IT alignment. It starts by mapping the dependencies of service level agreements, coming up with gradual and bi-polar concepts to eventually classify the level of coupling by intuitionistic fuzzy sets. The second part presents an approach to analyze the impact of service failures using intuitionistic fuzzy methods (IFSFIA). Lastly, the third part of the book extends the concept towards business and IT-aligned service-level engineering and provides two use cases.

Available in PDF, EPUB and Kindle. Book excerpt: The 2009 Symposium on Component-Based Software Engineering (CBSE 2009) was the 12thin a series ofsuccessful eventsthat havegrowninto the main forum for industrial and academic experts to discuss component technology. Component-based software engineering (CBSE) has emerged as the under- ing technology for the assembly of ?exible software systems. In essence, CBSE is about composing computational building blocks to construct larger building blocks that ful?ll client needs. Most software engineers are involved in some form of component-based development. Nonetheless, the implications of CBSE adoption are wide-reaching and its challenges grow in tandem with its uptake, continuing to inspire our scienti?c speculation. Component-based development necessarily involves elements of software - chitecture, modular software design, software veri?cation, testing, con?guration and deployment. This year’s submissions represent a cross-section of CBSE - search that touches upon all these aspects. The theoretical foundations of c- ponent speci?cation, composition, analysis, and veri?cation continue to pose research challenges. What exactly constitutes an adequate semantics for c- munication and composition so that bigger things can be built from smaller things? How can formal approaches facilitate predictable assembly through b- ter analysis? We have grouped the proceedings into two sub-themes that deal with these issues: component models and communication and composition. At the same time, the world is changing.
