“…In this paper we have analyzed the iKnow case study, as a mid-size project, where the specification grows fast. Usage of modeling tools like Winery [18] can ease this process. The greatest benefit is the promise of re-using the same specification by different cloud providers and environments.…”

“…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.

“…The Topology and Orchestration Specification for Cloud Applications (TOSCA) [19,20] is a specification developed by the OASIS consortium, which provides a language for specifying the components comprising the topology of Cloud-based applications along with the processes for their orchestration. TOSCA is comparable to CloudML, however the language has been conceived for design-time modelling only.…”

Model-Driven Development and Operation of Multi-Cloud Applications

The Cloud computing market encompasses an ever-growing number of providers offering a multitude of infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS) solutions. In order to exploit the peculiarities of each Cloud solution as well as to optimize performances, availability, and cost, an emergent need is to run and manage multi-Cloud applications [1] (i.e., applications that can execute on multiple Cloud infrastructures and platforms). However, current stacks, libraries and frameworks lack in software engineering methodologies and tools to design, deploy and maintain multi-Cloud systems as stated in the CORDIS reports on Cloud computing [2,3], "whilst a distributed data environment (IaaS) cannot be easily moved to any platform provider (PaaS) […], it is also almost impossible to move a service/image/environment between providers on the same level."Model-Driven Development (MDD) [4] techniques are particularly useful to address these challenges. They allow shifting the paradigm from code-centric to model-centric. Models are thus the main artefacts of the development process and enable developers to work at a high level of abstraction, focusing on Cloud concerns rather than implementation details. Model transformations help automating the work of going from abstract concepts to implementation. This approach, which is commonly summarized as "model once, generate anywhere", is thus particularly relevant when it comes to design and management of applications across multiple Clouds, N.

“…Thus, modifying, deleting or adding some components could provoke an error-prone task due to the need of maintaining the consistency of the initial topology description. In order to solve this problem, we propose to use the Winery tool [9], developed by the OpenTOSCA Team. This tool allows the representation of the application's modules through forms and the composition of the topology in a graphical way by means of the drag-and-drop technique.…”

Abstract. Cloud Computing platforms offer diverse services and capabilities with own features. Hence, the provider services could be used by end users to compose a heterogeneous context of multiple cloud platforms in order to deploy their cloud applications made up of a set of modules, according to the best capabilities of the cloud providers. However, this is an ideal scenario, since the cloud platforms are being conducted in an isolated way by presenting many interoperability and portability restrictions, which complicate the integration of diverse provider services to achieve an heterogeneous deployment of multi-cloud applications. In this ongoing work, we present an approach based on model transformation to deploy multi-cloud applications by reusing standardization efforts related to the management and deployment of cloud applications. Specifically, using mechanisms specified by both standards, TOSCA and CAMP, we propose a methodology to describe the topology and distribution of modules of a cloud application and to deploy the interconnected modules over heterogeneous clouds. We illustrate our idea using a running example.
