What are Developers' Preferences on Platform as a Service? : An Empirical Investigation

2013-01-07 , Giessmann, Andrea , Stanoevska-Slabeva, Katarina

Platform as a service (PaaS) solutions are changing the way how software is produced, distributed, consumed, and priced. Due to the wide variety of approaches to PaaS and the absence of a formula that represents the drivers of successful platforms, the goal of this paper is to identify developers' preferences on PaaS. An adaptive choice-based conjoint analysis has been performed and was completed by 103 participants. Based on the results, a prioritized list of developers' preferences for PaaS has been created. The results of the survey indicate that, third-party developers' preferences also depend on the phase of the software lifecycle in which they are (Development, Distribution, and Operation).

Grid and Cloud Computing : A Business Perspective on Technology and Applications

2010 , Stanoevska-Slabeva, Katarina , Wozniak, Thomas , Ristol, Santi

In today's dynamic business environment, IT departments are under permanent pressure to meet two divergent requirements: to reduce costs and to support business agility with higher flexibility and responsiveness of the IT infrastructure. Grid and Cloud Computing enable a new approach towards IT. They enable increased scalability and more efficient use of IT based on virtualization of heterogeneous and distributed IT resources. This book provides a thorough understanding of the fundamentals of Grids and Clouds and of how companies can benefit from them. A wide array of topics is covered, e.g. business models and legal aspects. The applicability of Grids and Clouds in companies is illustrated with four cases of real business experiments. The experiments illustrate the technical solutions and the organizational and IT governance challenges that arise with the introduction of Grids and Clouds. Practical guidelines on how to successfully introduce Grids and Clouds in companies are provided.
