Röck, C., Kolb, S.: Nucleus - Unified Deployment and Management for Platform as a Service
Bamberger Beiträge zur Wirtschaftsinformatik und Angewandten Informatik Nr. 100, University of Bamberg, April 2016.

Abstract—Cloud computing promises several advantages over classic IT models and has undoubtedly been one of the most hyped topics in the industry over the last couple of years. Besides the established delivery models Infrastructure as a Service (IaaS) and Software as a Service (SaaS), especially Platform as a Service (PaaS) has attracted significant attention these days. PaaS facilitates the hosting of scalable applications in the cloud by providing managed and highly automated application environments. Although most offerings are conceptually comparable to each other, the interfaces for application deployment and management vary greatly between vendors. Despite providing similar functionalities, technically different workflows and commands provoke vendor lock-in and hinder portability as well as interoperability. In this study, we present the tool Nucleus, which realizes a unified interface for application deployment and management among cloud platforms. With its help, we aim to increase the portability of PaaS applications and thus help to avoid critical vendor lock-in effects.
