Cloud Computing gewinnt stetig an Bedeutung, wie am wachsenden Markt von Dienstleistungen in den Bereichen IT-Infrastruktur, Entwicklungsplattformen und Software erkennbar ist. Für Unternehmen ergeben sich daraus neue Möglichkeiten, ihren IT-Bedarf zu decken. Zentrales Bewertungskriterium ist hierbei der ökonomische Nutzen, der durch die Nutzung von Cloud-Angeboten im Vergleich zu Anschaffung u...

Advances in networking technology and an increase in the need for computing resources have prompted many organizations to outsource their storage and computing needs. This new economic and computing model is commonly referred to as cloud computing and includes various types of services such as: infrastructure as a service (IaaS), where a customer makes use of a service provider’s computing, sto...

Die Nutzung von cloudbasierten Services wird als einer der Hauptbausteine der aktuellen Digitalisierungsals Industrie 4.0-Initiativen angesehen. Mittlerweile haben sich alle großen Anbieter von ITInfrastruktur-Services auch als Cloud-Anbieter positioniert. In diesem Beitrag werden die für eine Migration auf cloudbasierte Services – in ihren aktuellen Ausprägungen IaaS, PaaS und SaaS – notwendig...

In this paper, we are going to introduce new services in Cloud Computing environment. Three Cloud Computing services are already classified by the researchers such as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Each of defined services serves distinct purpose. Here, we propose some more fundamental services which are still undefined to the ...

The new era of computing called Cloud Computing allows the user to access the cloud services dynamically over the Internet wherever and whenever needed. Cloud consists of data and resources; and the cloud services include the delivery of software, infrastructure, applications, and storage over the Internet based on user demand through Internet. In short, cloud computing is a business and econom...

Especially the public cloud model promises several business related benefits such as cost-reduction, enhanced flexibility and increasing agility. However, there are several issues that challenge the enterprise-wide usage of public clouds leaving the potential gains virtually untapped. It is assumed that re...

Cloud computing and Enterprise Interoperability could help enterprises flexibly fit market challenges, collaborating with their partners. Cloud computing models can be splited into three basic designs: Infrastructure-as-a-Service (IaaS); Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Recently, everything/ anything as a Service (XaaS) is becoming a mainstream of evolution of clou...

Although the benefits of service orientation are prevalent in literature, a review, analysis, and evaluation of the 30 existing service analysis approaches presented in this paper have shown that a comprehensive approach to the identification and analysis of both business and supporting software services is missing. Based on this evaluation of existing approaches and additional sources, we clos...

Cost models are fundamental building blocks for cloud computing. Cloud providers offer a very wide portfolio of services, while Cloud clients access them against some financial arrangement. There is a fundamental tradeoff between what Cloud provider can offer in terms of resources (software or hardware), services (e.g., storage, e-mail) cost and what Cloud clients are willing to pay. The Cloud ...
