In the race to minimize operational costs, Software as a Service (SaaS) platforms has become increasingly popular. The development of SaaS, however, introduces several aspects that must be considered. In this paper, we present the continuous deployment pipeline of our eTrusted Enterprise SaaS Platform. Thereby, we focus on lessons learned during the evolution of our Continuous Deployment Pipeli...

When creating service compositions from a very large number of atomic service operations, it is inherently difficult for the modeler to discover suitable operations for his particular goal. Automated service composition claims to solve this problem, but only works if complete and correct ontologies alongside with service descriptions are in place. In this paper, we present a semi-automated mode...

This paper explores possible steps toward incorporating the increasingly important topics of service and service systems into the core of the IS field, thereby moving toward a service-oriented core without abandoning existing tool-oriented concepts and methods. Incorporating more of a service mindset into IS would add to the many service-related topics that it already contains. A service mindse...

The availability of an increasing number of cloud offerings allows for innovative solutions in designing applications for the cloud and in adapting existing ones for this environment. An important ingredient in identifying the optimal distribution of an application in the cloud, potentially across offerings and providers, is a robust topology model that can be used for the automated deployment ...

Self-service terminals (SSTs) are becoming an increasing important part of the service landscape for both the public and private sector. There is very little information regarding the current state of accessibility practice in this area. This paper presents the results of interviews with 22 stakeholders in the supply and deployment communities for SSTs regarding their knowledge of accessibility...

Cloud computing brings advancement in the field of information technology. Cloud computing is based on several service models such as SaaS, PaaS, NaaS, DbaaS, IaaS and many more. In order to make clear the essential of cloud computing, we propose the characteristics of these service models which distinguish cloud computing from other research areas .These service models are compared from variou...

The integration of research in the area of Service Oriented Architectures (SOA) with current methodologies and tools of Business Processes Management Systems (BPMS) will bring significant contributions to the objectives of dynamic process management in modern enterprises. However, at the current state of development of both BPMS and SOA, this dynamism is limited by numerous factors. This articl...

Nowadays, numerous journals have published papers related to biocloud – cloud computing techniques for biological applications (e.g., genome analysis, systems biology, infection disease), indicating many researchers’ interest. Therefore, the goal of this paper is to review the works that were published in journals from 2006 to 2013, suggest a classification framework of cloud computing techniqu...

In light of the massive developments in Information Technology (IT) in the past few years, there has been a recent debate in the literature on the economic impact of IT. Of particular interest has been the role of the ‘New Economy’ sectors (hardware, software, and communications) in bringing about economic growth and productivity revival in the United States. While on a much smaller scale, Egyp...
