TL;DR: The results demonstrate that federated Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.
Abstract: Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world However, existing systems do not support mechanisms and policies for dynamically coordinating load distribution among different Cloud-based data centers in order to determine optimal location for hosting application services to achieve reasonable QoS levels Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination must happen automatically, and distribution of services must change in response to changes in the load To counter this problem, we advocate creation of federated Cloud computing environment (InterCloud) that facilitates just-in-time, opportunistic, and scalable provisioning of application services, consistently achieving QoS targets under variable workload, resource and network conditions The overall goal is to create a computing environment that supports dynamic expansion or contraction of capabilities (VMs, services, storage, and database) for handling sudden variations in service demands.
This paper presents vision, challenges, and architectural elements of InterCloud for utility-oriented federation of Cloud computing environments The proposed InterCloud environment supports scaling of applications across multiple vendor clouds We have validated our approach by conducting a set of rigorous performance evaluation study using the CloudSim toolkit The results demonstrate that federated Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.

TL;DR: A process and a suitable system architecture is proposed that enables developers and business process designers to dynamically query, select, and use running instances of real-world services (i.e., services running on physical devices) or even deploy new ones on-demand, all in the context of composite, real- world business applications.
Abstract: The increasing usage of smart embedded devices in business blurs the line between the virtual and real worlds. This creates new opportunities to build applications that better integrate real-time state of the physical world, and hence, provides enterprise services that are highly dynamic, more diverse, and efficient. Service-Oriented Architecture (SOA) approaches traditionally used to couple functionality of heavyweight corporate IT systems, are becoming applicable to embedded real-world devices, i.e., objects of the physical world that feature embedded processing and communication. In such infrastructures, composed of large numbers of networked, resource-limited devices, the discovery of services and on-demand provisioning of missing functionality is a significant challenge. We propose a process and a suitable system architecture that enables developers and business process designers to dynamically query, select, and use running instances of real-world services (i.e., services running on physical devices) or even deploy new ones on-demand, all in the context of composite, real-world business applications.

TL;DR: This paper proposes an approach based on the notion of skyline to effectively and efficiently select services for composition, reducing the number of candidate services to be considered, and discusses how a provider can improve its service to become more competitive and increase its potential of being included in composite applications.
Abstract: Web service composition enables seamless and dynamic integration of business applications on the web. The performance of the composed application is determined by the performance of the involved web services. Therefore, non-functional, quality of service aspects are crucial for selecting the web services to take part in the composition. Identifying the best candidate web services from a set of functionally-equivalent services is a multi-criteria decision making problem. The selected services should optimize the overall QoS of the composed application, while satisfying all the constraints specified by the client on individual QoS parameters. In this paper, we propose an approach based on the notion of skyline to effectively and efficiently select services for composition, reducing the number of candidate services to be considered. We also discuss how a provider can improve its service to become more competitive and increase its potential of being included in composite applications. We evaluate our approach experimentally using both real and synthetically generated datasets.

TL;DR: In this article, the STOF model provides a holistic view on business models with four interrelated perspectives, i.e., service, technology, organization, and finance, and elaborates on critical design issues that ultimately shape the business model and drive its viability.
Abstract: Modern economies depend on innovation in services for their future growth. Service innovation increasingly depends on information technology and digitization of information processes. Designing new services is a complex matter, since collaboration with other companies and organizations is necessary. Service innovation is directly related to business models that support these services, i.e. services can only be successful in the long run with a viable business model that creates value for its customers and providers. This book presents a theoretically grounded yet practical approach to designing viable business models for electronic services, including mobile ones, i.e. the STOF model and based on it the STOF method. The STOF model provides a holistic view on business models with four interrelated perspectives, i.e., Service, Technology, Organization and Finance. It elaborates on critical design issues that ultimately shape the business model and drive its viability.

TL;DR: This work conducts several large-scale evaluations on real-world Web services of quality-of-Service (QoS) performance and provides reusable research datasets for promoting the research of QoS-driven Web services.
Abstract: Quality-of-Service (QoS) is widely employed for describing non-functional characteristics of Web services. Although QoS of Web services has been investigated in a lot of previous works, there is a lack of real-world Web service QoS datasets for validating new QoS based techniques and models of Web services. To study the performance of real-world Web services as well as provide reusable research datasets for promoting the research of QoS-driven Web services, we conduct several large-scale evaluations on real-world Web services. Firstly, addresses of 21,358 Web services are obtained from the Internet. Then, invocation failure probability performance of 150 Web services is assessed by 100 distributed service users. After that, response time and throughput performance of 5,825 Web services are evaluated by 339 distributed service users. Detailed experimental results are presented in this paper and comprehensive Web service QoS datasets are publicly released for future research.

TL;DR: A quick introduction to cloud storage is given, which covers the key technologies in Cloud Computing and Cloud Storage, several different types of clouds services, and describes the advantages and challenges of Cloud Storage after the introduction of the Cloud Storage reference model.
Abstract: As an emerging technology and business paradigm, Cloud Computing has taken commercial computing by storm. Cloud computing platforms provide easy access to a company’s high-performance computing and storage infrastructure through web services. With cloud computing, the aim is to hide the complexity of IT infrastructure management from its users. At the same time, cloud computing platforms provide massive scalability, 99.999% reliability, high performance, and specifiable configurability. These capabilities are provided at relatively low costs compared to dedicated infrastructures. This article gives a quick introduction to cloud storage. It covers the key technologies in Cloud Computing and Cloud Storage, several different types of clouds services, and describes the advantages and challenges of Cloud Storage after the introduction of the Cloud Storage reference model.
TL;DR: Evaluating the accomplishments and opportunities for research related to the SSME perspective through a robust framework enables in-depth assessment in the present, as well as an ongoing evaluation of new knowledge in this area.
Abstract: The increasing importance of information technology (IT) services in the global economy prompts researchers in the field of information systems (IS) to give special attention to the foundations of managerial and technical knowledge in this emerging arena of knowledge. Already we have seen the computer science discipline embrace the challenges of finding new directions in design science toward making services-oriented computing approaches more effective, setting the stage for the development of a new science-service science, management, and engineering (SSME). This paper addresses the issues from the point of view of service science as a fundamental area for IS research. We propose a robust framework for evaluating the research on service science, and the likely outcomes and new directions that we expect to see in the coming decade. We emphasize the multiple roles of producers and consumers of services-oriented technology innovations, as well as value-adding seller intermediaries and systems integrators, and standards organizations, user groups, and regulators as monitors. The analysis is cast in multidisciplinary terms, including computer science and IS, economics and finance, marketing, and operations and supply chain management. Evaluating the accomplishments and opportunities for research related to the SSME perspective through a robust framework enables in-depth assessment in the present, as well as an ongoing evaluation of new knowledge in this area, and the advancement of the related management practice capabilities to improve IT services in organizations.

TL;DR: The use of Web Services to enable programmatic access to on-line bioinformatics is becoming increasingly important in the Life Sciences, but their number, distribution and the variable quality of their documentation can make their discovery and subsequent use difficult.
Abstract: The use of Web Services to enable programmatic access to on-line bioinformatics is becoming increasingly important in the Life Sciences. However, their number, distribution and the variable quality of their documentation can make their discovery and subsequent use difficult. A Web Services registry with information on available services will help to bring together service providers and their users. The BioCatalogue (http://www.biocatalogue.org/) provides a common interface for registering, browsing and annotating Web Services to the Life Science community. Services in the BioCatalogue can be described and searched in multiple ways based upon their technical types, bioinformatics categories, user tags, service providers or data inputs and outputs. They are also subject to constant monitoring, allowing the identification of service problems and changes and the filtering-out of unavailable or unreliable resources. The system is accessible via a human-readable 'Web 2.0'-style interface and a programmatic Web Service interface. The BioCatalogue follows a community approach in which all services can be registered, browsed and incrementally documented with annotations by any member of the scientific community.
TL;DR: Methods and important fields of action regarding the systematization of services – service engineering (SE) – as well as the integration of products and services – industrial product-service systems (PSS) – are presented.
Abstract: The growing demand for innovative services forces traditional product-oriented companies to perceive the potentials and strategic importance of services. Innovative services enable these companies to ensure their market positions and to achieve economical success. Due to this, it becomes necessary to systemize service design, development and management processes as well as to tightly integrate products and services. In this paper, methods and important fields of action regarding the systematization of services – service engineering (SE) – as well as the integration of products and services – industrial product-service systems (PSS) – are presented.

TL;DR: This paper summarizes, classifies and evaluates major research efforts in service compositions, and gives an overview about further open research questions.
Abstract: Service compositions build new services by orchestrating a set of existing services. In the Internet of Services there may be many functional similar services, but with different Quality of Service (QoS). Thus a significant research problem in service compositions is how to select the composition’s composite services that the overall QoS of the composition is being maximized. This paper summarizes, classifies and evaluates major research efforts in this area and gives an overview about further open research questions.

TL;DR: This book provides comprehensive coverage of the state of the art in cloud computing, highlighting and clarifying the conceptual and systemic links with other distributed computing approaches.
Abstract: Cloud computing has recently emerged as a subject of substantial industrial and academic interest, though its meaning and scope is hotly debated. For some researchers, clouds are a natural evolution towards the full commercialisation of grid systems, while others dismiss the term as a mere re-branding of existing pay-per-use technologies. From either perspective, "cloud" is now the label of choice for accountable pay-per-use access to third party applications and computational resources on a massive scale. Clouds support patterns of less predictable resource use for applications and services across the IT spectrum, from online office applications to high-throughput transactional services and high-performance computations involving substantial quantities of processing cycles and storage. The concept of clouds seems to blur the distinctions between a variety of technologies that encompass grid services, web services and data centres, and leads to considerations of lowered-cost provisioning for bursty applications. This book provides comprehensive coverage of the state of the art in cloud computing, highlighting and clarifying the conceptual and systemic links with other distributed computing approaches.

TL;DR: Six categories of Cloud Computing services are divided into six categories and detailed analysis to these services are provided, as well as those companies which provide the corresponding service categories.
Abstract: Cloud Computing is becoming a well-known buzzword nowadays. As a brand new infrastructure to offer services, Cloud Computing systems have many superiorities in comparing to those existed traditional service provisions, such as reduced upfront investment, expected performance, high availability, infinite scalability, tremendous fault-tolerance capability and so on and consequently chased by most of the IT companies, such as Google, Amazon, Microsoft, Salesforce.com. Based on their overwhelming predominance in traditional service provisions and capital accumulation, most of these IT companies have more chance to adapt their services into such a new environment earlier, say Cloud Computing systems. On the other hand, a large number of new companies are spawned with competitive services relayed on those provided Cloud Computing systems. In terms of their provisions, we divide those services into six categories in this paper, say Data as a Service (Daas), Software as a Service (SaaS), Platform as a Service (PaaS), Identity and Policy Management as a Service (IPMaaS), Network as a Service (NaaS), Infrastructure as a Service (IaaS). Detailed analysis to these services are provided, as well as those companies which provide the corresponding service categories.

TL;DR: It is argued that the recent evolution provides the missing ingredients that will lead to a new wave of services - Linked Services - that will ultimately witness a significant uptake on a Web scale.
Abstract: It has often been argued that Web services would have a tremendous impact on the Web, as a core enabling technology supporting a highly efficient service-based economy at a global scale. However, despite the outstanding progress in the area we are still to witness the application of Web services in any significant numbers on the Web. In this paper, we analyse the state of the art highlighting the main reasons we believe have hampered their uptake. Based on this analysis, we further discuss about current trends and development within other fields such as the Semantic Web and Web 2.0 and argue that the recent evolution provides the missing ingredients that will lead to a new wave of services - Linked Services - that will ultimately witness a significant uptake on a Web scale. Throughout the presentation of this vision we outline the main principles that shall be underpinning the development of Linked Services and we illustrate how they can be implemented using a number of technologies and tools we have developed and are in the process of extending.

TL;DR: This paper presents USDL (Unified Service Description Language), a specification language to describe services from a business, operational and technical perspective, which plays a major role in the Internet of Services to describe tradable services which are advertised in electronic marketplaces.
Abstract: Service-oriented Architectures (SOA) and Web services leverage the technical value of solutions in the areas of distributed systems and cross-enterprise integration. The emergence of Internet marketplaces for business services is driving the need to describe services, not only from a technical level, but also from a business and operational perspective. While, SOA and Web services reside in an IT layer, organizations owing Internet marketplaces are requiring advertising and trading business services which reside in a business layer. As a result, the gap between business and IT needs to be closed. This paper presents USDL (Unified Service Description Language), a specification language to describe services from a business, operational and technical perspective. USDL plays a major role in the Internet of Services to describe tradable services which are advertised in electronic marketplaces. The language has been tested using two service marketplaces as use cases.
TL;DR: FACTS is proposed, a framework for fault-tolerant composition of transactional Web services that combines exception handling and transaction techniques and an implementation module to automatically implement fault-handling logic in WS-BPEL.
Abstract: Along with the standardization of Web services composition language and the widespread acceptance of composition technologies, Web services composition is becoming an efficient and cost-effective way to develop modern business applications. As Web services are inherently unreliable, how to deliver reliable Web services composition over unreliable Web services is a significant and challenging problem. In this paper, we propose FACTS, a framework for fault-tolerant composition of transactional Web services. We identify a set of high-level exception handling strategies and a new taxonomy of transactional Web services to devise a fault-tolerant mechanism that combines exception handling and transaction techniques. We also devise a specification module and a verification module to assist service designers to construct fault-handling logic conveniently and correctly. Furthermore, we design an implementation module to automatically implement fault-handling logic in WS-BPEL. A case study demonstrates the viability of our framework and experimental results show that FACTS can improve fault tolerance of composite services with acceptable overheads.
