Value creation from e-business for customers in healthcare is an important topic in academic and practitioner circles. This chapter reports the findings from a two-year research study, which found that disappointing results from the muchhyped application service provider (ASP) business model is currently being replaced by perceived new opportunities from Web services. Yet past failings from ASP do not guarantee future success with Web services models, particularly as evidence shows that accruing value-added benefits from e-business initiatives is often fraught with difficulty. Healthcare is no exception, and is likely to pose more problems given the complexity of the organizational structures, processes, procedures, and activities within this vertical sector. This research study calls for a more rigorous approach in identifying and evaluating key performance areas and indicators from new e-business initiatives involving emerging technologies and platforms such as Web services. Yet the measures and metrics used for healthcare may differ from those adopted in other sectors. Healthcare professionals will therefore need to develop context specific key performance areas (KPAs) and KPIs, and caution against accepting at “face value” the value proposition devised by Web service providers.

Application Service

This paper draws from the findings of a large-scale empirical research program on the global application service provider (ASP) industry funded by research grants from the European Commission (EC) and the Engineering and Physical Sciences Research Council (EPSRC). A conceptual framework consisting of a taxonomy of ASPs is used to demonstrate the different market segmentation strategies adopted by ASPs for competing in this fledgling and turbulent industry. Drawing from empirical research carried out in the US and Europe, the paper evaluates ASP strategies for deploying, hosting, managing and enabling software applications on behalf of their customers. The ASP business model is advocated as an attractive value proposition for SMEs, dot.com companies and other start-up firms seeking hyper-growth. Yet the evidence so far suggests a slow start to the ASP market as few reference sites demonstrating best practice exist. ASPs will therefore need to re-evaluate their strategies if they are to convince potential customers of the benefits of application outsourcing. Against this background, the paper evaluates the benefits and risks of the ASP model.

Second Wave

How value is created for the customer from e-business is a topic of much concern in academic and practitioner circles. In the light of the dot.com downturn, numerous e-business firms ceased to exist. This paper reports the findings from an ongoing research study on the development and decline of the application service provider (ASP) industry. Having witnessed the decline of the first wave of ASPs, with many failing to convince small and medium businesses (SMBs) of the value of adopting an ASP solution, the second wave calls for a more rigorous approach that clearly identifies the key performance areas and indicators of the ASP business model. Applying the constructs of strategic positioning, product/service portfolio, and value proposition, this paper represents the findings from 215 responses to a questionnaire survey on how potential and existing ASP customers evaluate the benefits and risks of ASP. The findings suggest that, if the ASP model is to succeed, vendors will need to carefully identify customer requirements and avoid the pitfalls that beset the first wave of the ASP model, which was largely based upon a technology push strategy.

Semantic Web Service Composition

At present, more and more service providers carry on their business as a Web type. However, the function of individual Web services is very limited and the lack of semantic information, only can meet the needs for a single customer. In this paper, making Web services become an entities understood by the computer through introducing the concept of the Ontology. A framework of Semantic Web Service composition also is proposed based on Ontology for assembling basic Web services coming from different service providers and a solution is provided for to achieve value-added services based on a single service.

Composite Web Service

In Services Oriented Computing, a composite web service is a value-added service composed of loosely coupled, independent, and distributed component web services. Component or partner web services jointly contribute to fulfil functional as well as non-functional requirements of users of a composite web service. One of the fundamental challenges in Services Oriented Computing is to ensure that a composite web service is flexible enough to react to changes (QoS degradation) in its partner web services at the time of execution. In this context, it is important that the time to adapt to changes should not be significant. Several solutions exist for run-time monitoring of partner web services so that clients can replace them with better alternatives when their QoS values degrade. But these solutions follow either a reactive approach (which is time consuming), or a prediction-based proactive approach (again time consuming, and moreover predicted events may never happen). This article proposes a solution using a publish/subscribe mechanism which is distributed between web service clients and the service providers, and follows a proactive preventive approach. It uses mobile agents to communicate partner web service's QoS status to its clients just in time, in order to decide to choose an alternative in case the QoS values are not satisfactory. The prototype is implemented using JAVA and Java Agent DEvelopment framework (JADE) programming languages. The experimental results show effectiveness of the proposed approach when compared with a static approach (the benchmark), as well as with a reactive solution. Moreover, the framework performs well even in the wake of the increasing levels of QoS degradation of partner web services.

This chapter introduces the ASP (Application Service Provider) industry which provides essential infrastructure for the Internet-based e-business transactions. First introduced is the current status of the ASP industry with some industry analysis focusing on the driving forces shaping the evolutionary changes. Then, emerging ASP business models are classified and analyzed in order to assess their positions in the competitive landscape based on the economies of scale. We also explore the prerequisites for the success of each ASP business model. Lastly, a conceptual model is provided to predict some possible scenarios of the evolution of the industry structure. For example, we identify the prerequisites for the ASP business models to develop themselves into XSPs (eXtended Service Providers), and develop a scenario for that evolutionary path. The proposed framework will present a deep insight into the e-transformation and a way to improve enterprise intelligence and performance through ASPs.

Application Hosting

Application service providers (ASPs) are a new type of service providers that make the whole spectrum from low-end applications like e-mail systems to high-end applications like enterprise resource planning (ERP) management systems available to customers over the Internet through browser-based user interfaces (application hosting). This relieves a customer from installing and managing the applications himself in his own data center. Instead, the customer pays a fee for accessing the application over the Internet. However, as soon as a customer uses several applications hosted by different ASPs, a management burden arises for the customer as well as an application integration problem, since the applications are hosted individually by several ASPs without any coordination or data exchange between them. The arising integration (aggregation) problems are discussed in this chapter. An ASP aggregation architecture is defined based on B2B integration servers that address these problems by supporting the seamless access and seamless integration of all hosted applications hiding the differences between the ASPs.

Core Capability

The enterprise intelligence through e-transformation is one of the cornerstones of the next-generation e-business era where the Internet constitutes the core business resource. Furthermore, the severe competitive landscape of e-business makes firms focus on their core capability and farm out staffing functions such as IT. Under this circumstance, enhancing intelligence and synergy through e-transformation will be accomplished by IT outsourcing via ASPs (application service providers). The ASP industry now provides an essential infrastructure for the Internet-based e-business transactions, thereby accelerating corporate e-transformation.

Behavior Network

As Web services become more widely disseminated, tools are needed to help users find and integrate these services. As these services become more available, users and service providers will want to obtain new and value-added services by combining and reconfiguring existing services. We propose novel Web service composition based on a behavior network that selects services automatically through internal and external links with environmental information from sensor and goals. Optimal services are selected at each step, resulting in a globally optimal service sequence for achieving a preset goal. We developed our prototype using Amazon Web services to verify its feasibility. Experimental results comparing rule-based system and user tests demonstrated the potential of the behavior network for Web services applications.
