“…VNF properties such as resources needed (Compute, Storage, Networking), connectivity (External Connection points, Internal Virtual Links, Internal Connection Points) and lifecycle management behavior (Scaling, Instantiation) are defined within a VNF Descriptor (VNFD). The VNF Descriptor provided by the VNF vendor must comply with TOSCA based service template specified in ETSI NFV-SOL001 (Hung et al, 2017). (TOSCA stands for Topology and Orchestration Specification for Cloud Applications and provides a language to describe the topology for cloud services, their components, relationships and the processes for deploying and managing theses services throughout their lifecycle), one of the main parts of the VNFD is VNF topology modelized in a cloud agnostic, containing a set of VDUs (Virtual Deployment Units) that describes the capabilities of virtualized containers such as virtual CPU, RAM, disks…etc (Nguyen et al, 2018).…”

The demand for scalable, open and granular networks has enabled mobile networks such as 5G to adopt new concepts including NFV (Network Function Virtualization). NFV separates the dependency of network functions from the hardware component, allowing them to be deployed flexibly and dynamically across network slices. In this way, operators can deliver personalized services and optimize the use of network resources, contributing to greater operational efficiency and an enhanced end-user experience. However, there are several issues to be addressed, such as the security of VNFs and the way in which service provider customers instantiate NSSIs (Network Slice Subnet Instance). In this article, we present a new approach based on blockchain 2.0, which guarantees the immutability of VNFs and templates, as well as highly secure instantiation with access management and support for replay attacks.

“…We chose to extend TOSCA because it is a modelling language for defining portable deployment and automated management of services which is already commonly used to manage VNFs, NSs [19] and even IoT devices [20] [21]. It is also modular and enables to compose multiple components, thus achieving INSPIRE-5Gplus modularity requirement.…”

To address the growing amount of data generated by the Internet of Things (IoT), Network Functions Virtualization (NFV), 5G, Fog and Edge computing converge to form a Cloudto-IoT continuum. This complex multi-layer architecture involves several actors among which responsibilities may be blurred. Existing profiles mostly describe deployment aspects and elude responsibility, accountability or liability characteristics. Moreover, the multiplicity of component profiles prevents uniform service management. This paper proposes TRAILS (sTakeholder Responsibility, AccountabIity and Liability deScriptor), an extension of the TOSCA NFV profile that merges the existing profiles and adds a description of the responsibilities and accountabilities of supply chain actors. This allows a uniform and liability-aware management of services involving IoT devices, fog, edge and cloud nodes. To show the usability of our model, we discuss the ecosystem around the generation of the proposed extension as well as its application in an ontology-based referencing module of a liability-aware service manager that we designed.

“…Along with commercial and non-profit organisations, TOSCA has been widely adopted in other technologies, such as the Internet of Things (IoT) [23] [24] [25], Network Function Virtualization (NFV) [26] [27,28], quantum computing [6], fog and mobile edge computing [27]. TOSCA is mainly designed and developed to improve the portability and interoperability of the cloud technology [29].…”

The serverless platform allows a customer to effectively use cloud resources and pay for the exact amount of used resources. A number of dedicated open source and commercial cloud data management tools are available to handle the massive amount of data. Such modern cloud data management tools are not enough matured to integrate the generic cloud application with the serverless platform due to the lack of mature and stable standards. One of the most popular and mature standards, TOSCA (Topology and Orchestration Specification for Cloud Applications), mainly focuses on application and service portability and automated management of the generic cloud application components. This paper proposes the extension of the TOSCA standard, TOSCAdata, that focuses on the modeling of data pipeline-based cloud applications. Keeping the requirements of modern data pipeline cloud applications, TOSCAdata provides a number of TOSCA models that are independently deployable, schedulable, scalable, and re-usable, while effectively handling the flow and transformation of data in a pipeline manner. We also demonstrate the applicability of proposed TOSCAdata models by taking a web-based cloud application in the context of tourism promotion as a use case scenario.
