As the sector of SaaS is being evolved, the need of portability and effective orchestration of Cloud-enabled applications over virtualised infrastructures is more apparent. In this paper we present a proof of concept (PoC) project together with industry partners which deals with the management of portable Cloud applications. Experimentation with a multi-tier Cloud application use case gives insights into the capabilities of the TOSCA specification (version 1). To realize support for a Cloud environment based on OpenStack and Opscode Chef, an environment that allows the execution and management of TOSCA service topologies has been developed. For the evaluation of the implemented system, we orchestrate the un-/deployment of the multi-tier Cloud application use case and in the end we discuss the results and experiences of this exercise. © 2014 IEEE.

Virtualization is the foundation of modern, cloud-based applications. The existence of virtual machines (VM) that host the components of such applications enables their portability and scalability. VMs are used in cloud infrastructures, and with dynamic operational requirements there is a need to move VMs within and across different clouds. The successful migration of VMs from one cloud to another should not always be considered as given. The goal of this paper is to devise and implement methods and conduct functional tests towards evaluating interoperability in cloud environments. We suggest a methodology for assessing the interoperability across different systems and we conduct a survey with a series of hypervisors and operating systems. © 2014 IEEE.

The Development and Implementation of PHM systems require a different approach than typical application development processes. Based on a practical example it is described how ethical and legal aspects will be considered during the development process. The result is a cohesion and adoption of different methods with defined interaction points to reiterate the solution design by legal and ethical aspects.
