Abstract = {Since the advent of service-orientation various scholars have proposed methods to identify services. Some of these methods were developed as parts of proprietary SOA frameworks others were purely theoretical research. However, the task of deriving service candidates from heterogeneous inputs has not yet been sufficiently solved. Within this article an explorative evaluation of one of the most recent approaches in the field is conducted. The approach is consecutively applied to two real-world cases. Finally the current state of service identification with regard to the investigated approach is drawn and an outlook on future research is given.},

Abstract = {The Open Source Software development model has gained a lot of momentum in the latest years providing organizations and software engineers with a variety of software, components and libraries that can be exploited in the construction of larger application systems. Open Source Software is accompanied by licenses that state the conditions under which the intellectual property can be used. Since not all licenses are governed by the same conditions of use, the correct combination of licenses is vital, when different libraries are exploited in newly developed application systems. If this is not adequately handled, license violations might be a consequence of incompatibilities. In this paper we present our work on license violation checking in the framework of Software Package Data Exchange (SPDX). Starting from the modelling of license compatibilities our approach examines potential violations in software package information formatted using the SPDX specification. At the same time alternative solutions in the form of applicable licenses for the software package are proposed. This approach can be a valuable asset for Open Source practitioners in the license decision process assisting in detecting possible violations and in making suggestions on license use.},

Abstract = {Das Interesse an Open Source Enterprise Resource Planning (OSS-ERP) steigt kontinuierlich. Zwar fallen keine Lizenzkosten an, die Einführung ist jedoch komplex und damit in der Regel kostenintensiv. Es müssen Anforderungen aufgenommen, Geschäftsprozesse dokumentiert und implementiert, Rollenkonzepte erarbeitet, Schulungen vorbereitet, Support sichergestellt und zusätzliche Anwendungssysteme angebunden werden. In Anbetracht dieser Aufwände, treten wichtige Vorteile von OSS-ERP wie Flexibilität und Vermeidung von Anbieterabhängigkeiten (sogenannten Lock-Ins) häufig in den Hintergrund. Der vorliegende Beitrag diskutiert die in kleinen und mittleren Unternehmen (KMU) auftretenden Probleme und diskutiert Lösungsansätze zu deren Vermeidung.},

Abstract = {Cloud computing (CC) and open source software (OSS) both stand out to be valuable means to address prevailing requirements of small and medium-sized enterprises (SME). For instance, such requirements include their demand for flexibility, scarcity of skills and money, and their operative focus. This paper investigates the case of e-commerce adoption by means of CC and OSS in a venture capital driven entrepreneurial SME in the online retail industry. The case study provides qualitative evidence that some of the commonly asserted value propositions of CC and OSS do not hold true in real application scenarios. For instance, the cost-saving and flexibility aspect, often mentioned with regard to CC, seems to be largely questionable. Even though OSS can help to save money, its pay-off on the scarcity of skills and flexibility requirements of SME is seen to largely prevail.},

Abstract = {Cloud Computing has become an important driver for IT service provisioning in recent years. In addition to its associated benefits for both customers and IT service providers, cloud computing also comes along with new challenges. One of the major challenges for providers is to reduce the energy consumption, since today already more than fifty percent of operational costs in data centers account for energy. A possible way to reduce these costs is to distribute load in terms of virtual machines within the data center. Developing algorithms for this purpose has been a topic of recent research. In order to capture the state of the art of energy efficient load distribution in clouds, this paper presents a structured literature review on load distribution algorithms that aim to reduce the energy consumption in data centers for cloud computing. The algorithms are reviewed in terms of their type, the evaluation method and its potential side effects in terms of drawbacks.},

Abstract = {As business applications such as highly integrated Enterprise Resource Planning systems (ERP) become more complex, system-integrated business simulation games are vital for educating tomorrow’s white collar work force. Especially for small and medium-sized enterprises (SME) cloud-based business applications are a serious alternative. The Education as a Service (EaaS) approach gets more and more into the focus, hence. In order to yield a fruitful scientific dispute on the matter a cloud-based simulation game design is proposed in this paper. That design also identifies challenges implementing and operating a cloud-based simulation game. It reveals issues such as the composition of the simulation model and its relation to the host system as well as communication matters (change of interfaces) and the coordination between customer, host system and the simulation itself. Furthermore, the choice of the right service and deployment model affects the design of the simulation game.},
