SOA is moving towards Software as a Service (SaaS), which extends known SOA approaches. This article discusses challenges and future directions and how communities can contribute to the paradigm change.

The integration of SaaS service for group user in cloud is challenging, notably because the service’s QoS and member’s personalization QoS preference in group are uncertain. This is a timely and importance problem with the advent of the SaaS model of service delivery. Therefore, before the SaaS service been utilized, the service alternatives must be ranked for group user based on services’ QoS ...

The paper evaluates the application service provider (ASP) business model. It draws from a large scale research program funded by the European Union and Engineering and Physical Sciences Research Council (EPSRC), into the emerging ASP industry where software is delivered as a service, priced on a per-seat, per month basis. Tracking a taxonomy of ASPs (pure-play, vertical, horizontal, enterprise...

Business information services are intermediaries that collect, collate, package and distribute information of value to professional users. We consider two technologies that such intermediaries may use for delivering information. First, a packaged design that uses physical media like CD-ROMs to distribute information. Second, an online service that delivers such information via the Internet or o...

Software-as-a-Service, a new model of accessing software presents individual users with tremendous opportunities to work and live conveniently and efficiently. However, the challenges that come with SaaS are equally highlighted and deserve careful attention from researchers. Among them, privacy has emerged as the key inhibitor of SaaS adoption and use among individual users. The purpose of this...

I n 1999, the Pennine Group—a consortium of software engineering researchers from the University of Durham, Keele University, and the University of Manchester Institute of Science and Technology—asserted that continued development of new architectural styles based on constructional forms such as objects or components would not advance the software field. Rather, they foresaw a future in which d...

This article discusses the recent technology transfer to Chinese software firms from Japanese offshore software development. Since the end of the 1990s, Chinese software firms have obtained a significant amount of technology contract work from Japan, including coding, testing, and design. Chinese firms have been increasing their design skills through this joint software development with Japan. ...

Cloud Computing, i. e. providing on-demand access to virtualised computing resources over the Internet, is one of the current megatrends in IT. Today, there are already several providers offering cloud computing infrastructure (IaaS), platform (PaaS) and software (SaaS) services. Although the cloud computing paradigm promises both economical as well as technological advantages, many potential u...

Cloud computing, the long-held dream of computing as a utility, has finally came to realization. Cloud computing has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. Developers with innovative ideas for new Internet services no longer require the large capital outlays in hardw...

The cloud computation is a recently evolved computing terminology at variance capabilities are provided as a service to customers using internet technologies. The most common offered services are Infrastructure (IaaS), Software (SaaS) and Platform (PaaS). This work segregates the service management into the cloud computing idea and shows how management can be provided as a service in the cloud....
