Cloud service benchmarking can provide important, sometimes surprising insights into the quality of services and leads to a more quality-driven design and engineering of complex software architectures that use such services. Starting with a broad introduction to the field, this book guides readers step-by-step through the process of designing, implementing and executing a cloud service benchmark, as well as understanding and dealing with its results. It covers all aspects of cloud service benchmarking, i.e., both benchmarking the cloud and benchmarking in the cloud, at a basic level.The book is divided into five parts: Part I discusses what cloud benchmarking is, provides an overview of cloud services and their key properties, and describes the notion of a cloud system and cloud-service quality. It also addresses the benchmarking lifecycle and the motivations behind running benchmarks in particular phases of an application lifecycle. Part II then focuses on benchmark design by discussing key objectives (e.g., repeatability, fairness, or understandability) and defining metrics and measurement methods, and by giving advice on developing own measurement methods and metrics. Next, Part III explores benchmark execution and implementation challenges and objectives as well as aspects like runtime monitoring and result collection. Subsequently, Part IV addresses benchmark results, covering topics such as an abstract process for turning data into insights, data preprocessing, and basic data analysis methods. Lastly, Part V concludes the book with a summary, suggestions for further reading and pointers to benchmarking tools available on the Web.The book is intended for researchers and graduate students of computer science and related subjects looking for an introduction to benchmarking cloud services, but also for industry practitioners who are interested in evaluating the quality of cloud services or who want to assess key qualities of their own implementations through cloud-based experiments.

This book constitutes the refereed proceedings of the First International Conference on Engineering and Employment of Cooperative Information Systems, EDCIS 2002, held in Beijing, China, in September 2002. The 44 revised full papers presented were carefully reviewed and selected from 159 submissions. The papers are organized on topical sections on workflow, ontologies, semantic web, enterprise application integration, mobile agents, enterprise modelling, distributed systems, analysis, software engineering, architectures, transactions, coordination, and groupware.

The BPM Conference series has established itself as the premier forum for - searchersintheareaofbusinessprocessmanagementandprocess-awareinfor- tion systems. It has a record of attracting contributions of innovative research of the highest quality related to all aspects of business process management, including theory, frameworks, methods, techniques, architectures, systems, and empirical ?ndings. BPM 2010 was the 8th conference of the series. It took place September 14- 16, 2010 on the campus of Stevens Institute of Technology in Hoboken, New Jersey, USA—with a great view of Manhattan, New York. This volume c- tains 21 contributed research papers that were selected from 151 submissions. The thorough reviewing process (each paper was reviewed by three to ?ve P- gram Committee members followed in most cases by in-depth discussions) was extremely competitive with an acceptance rate of 14%. In addition to the c- tributed papers, these proceedings contain three short papers about the invited keynote talks. In conjunction with the main conference, nine international workshops took place the day before the conference. These workshops fostered the exchange of fresh ideas and experiences between active BPM researchers, and stimulated discussions on new and emerging issues in line with the conference topics. The proceedings with the papers of all workshops will be published in a separate volume of Springer’s Lecture Notes in Business Information Processing series. Beyond that, the conference also included a doctoral consortium, an industry program, ?reside chats, tutorials, panels, and demonstrations.

Cloud Computing erlaubt die Bereitstellung und Nutzung von IT-Infrastruktur, von Plattformen und von Anwendungen aller Art als im Web elektronisch verfügbare Dienste. Cloud Computing folgt dabei den Ideen des Utility Computing, dh. es wird immer die aktuell benötigte Menge an Ressourcen zur Verfügung gestellt und abgerechnet. Dieses Buch will einen Überblick über Cloud Computing Architektur, Anwendungen und Entwicklung vermitteln. Ziel ist es, die Leserinnen und Leser auf einen einheitlichen Stand zu bringen und so eine gemeinsame Diskussionsgrundlage zu erreichen. Technische Vorkenntnisse sind nicht erforderlich.

Instead, as a result of the multi-faceted viewpoints and the diverse interests expressed by the various stakeholders, cloud computing is perceived as a rather fuzzy concept.With this book, the authors deliver an overview of cloud computing architecture, services, and applications.
