“…There are no commercial environments that enable usage of this specification, besides the several efforts made in this area for open-source solutions [17], [16]. Although it is promising, there is no guarantee of a wider acceptance by major cloud providers and software developers; and further standard commercialization.…”

“…The TOSCA technical committee has published the first version of a standard for "interoperable description of application and infrastructure cloud services, the relationships between parts of the service, and the operational behavior of these services (e.g., deploy, patch, shutdown)" [2]. This initiated a spread of research activities in different directions, such as IBM efforts to implement this standard [14], [15], creation of environment for execution [16], [17], modeling tools [18], [19] and attempt to create this type of specification [20].…”

Abstract-Portability of developed solutions is a huge challenge for both the customers and cloud providers. A typical customer would like to realize a flexible software solution which can be easily deployed on a selected infrastructure or transferred on a cloud environment. Finally, the idea of a software environment independent of a specific cloud provider enables preferable conditions for customers.These portability issues are analyzed for a case study of a custom University Management System -iKnow, used by the University Ss. Cyril and Methodius in Macedonia. This paper presents implementation of a Topology and Orchestration Specification for Cloud Applications (TOSCA) specification to enable a software solution to be deployed on a flexible and portable environment.The motivation to consider the implementation of such a platform is initiated due to the rising number of students that use the iKnow system, reaching the peak during the enrollment periods. A possible solution is to consider the possibility of moving the iKnow system (or its part) to a cloud environment and balance the workload using flexible resources. We conducted research to describe the iKnow system using the TOSCA specification and to enable a rather easy deployment and maintenance. This paper presents the challenges and issues regarding the TOSCA specification while implemented on the iKnow system.

Abstract-Network Function Virtualization (NFV) has drawn significant attention from both industry and academia as an important shift in telecommunication service provisioning. By decoupling Network Functions (NFs) from the physical devices on which they run, NFV has the potential to lead to significant reductions in Operating Expenses (OPEX) and Capital Expenses (CAPEX) and facilitate the deployment of new services with increased agility and faster time-to-value. The NFV paradigm is still in its infancy and there is a large spectrum of opportunities for the research community to develop new architectures, systems and applications, and to evaluate alternatives and trade-offs in developing technologies for its successful deployment. In this paper, after discussing NFV and its relationship with complementary fields of Software Defined Networking (SDN) and cloud computing, we survey the state-of-the-art in NFV, and identify promising research directions in this area. We also overview key NFV projects, standardization efforts, early implementations, use cases and commercial products.

“…We realized the prototype as a REST-based web-service that reuses following specifications and tools: We apply the Topology Orchestration Specification for Cloud Applications (TOSCA) [6] for resource deployment. OpenTOSCA [5] is an open-source container (i.e., resource organizer) for cloud applications defined in TOSCA. Winery [24] is the corresponding modeling tool for specifying TOSCA-based applications.…”

Abstract. Traditional workflow and activity-centric coordination offers limited process support to human collaborators when unanticipated situations predominate. Under such circumstances, informal processes focus on provisioning relevant resources for achieving collaboration goals. Resources include interaction mechanisms such as shared artifact, social networks, and publish/subscribe information dissemination as complex situations typically demand the close collaboration among multiple human process participants. Currently, however, there exists a gap between (i) selecting and configuring suitable interaction mechanisms (collaboration level) and (ii) deploying the respective collaboration platforms (IT level). In this paper, we present an approach and techniques for transforming collaboration structures into automatically deployable informal processes. We demonstrate how our tools support the specification of desirable collaboration capabilities subsequently deployed to multiple MediaWiki instances.
