Toward an open cloud standard

Today's cloud ecosystem features several increasingly divergent management interfaces. Numerous bridging efforts attempt to ameliorate the resulting vendor lock-in for customers. However, as the number of providers continues to grow, the drawback of this approach becomes apparent: the need to maintain adapter implementations. The Open Cloud Computing Interface builds on the fundamentals of modern Web-based services to define a standardized interface for cloud environments while enabling service providers to differentiate their service offerings at the same time

AI-powered edge computing evolution for beyond 5G communication networks

Edge computing is a key enabling technology that is expected to play a crucial role in beyond 5G (B5G) and 6G communication networks. By bringing computation closer to where the data is generated, and leveraging Artificial Intelligence (AI) capabilities for advanced automation and orchestration, edge computing can enable a wide range of emerging applications with extreme requirements in terms of latency and computation, across multiple vertical domains. In this context, this paper first discusses the key technological challenges for the seamless integration of edge computing within B5G/6G and then presents a roadmap for the edge computing evolution, proposing a novel design approach for an open, intelligent, trustworthy, and distributed edge architecture.VERGE has received funding from the Smart Networks and Services Joint Undertaking (SNS JU) under the European Union’s Horizon Europe research and innovation programme under Grant Agreement No 101096034.Peer ReviewedPostprint (author's final draft

Content-validation of Messages and Policy assurances for a Security-Proxy supporting Grid services

Today Grid computing is an important technology that allows scientists and engineers to solve large and complex problems, to work in complex and heterogeneous environments, and to cooperate in various new ways. In Grid environments integrate distributed computing resources, networks, scientific instruments, data archives and databases, and visualization environments. The virtualization of these resources results in resource environments allowing the dynamic generation of Virtual Organizations (VO) to increase the productivity and quality of scientific work. This work describes a security concept for securing Grid Services in a Firewalled environment. The main aspect of this concept is a security gateway which performs content based checks on incoming Grid requests. This is an application level gateway and it checks SOAP messages of Grid Service requests and decides on the application level (OSI level 7) whether the message should pass the gateway or be blocked. In combination with packet filtering, provided by usual rewall solutions, and encrypted data transfer methods, this allows a shared secured use of Grid resources, separated by security gateways. This can be accomplished without changing the respective Grid middleware and without increasing security risks to an unacceptable level (e. g., by opening network ports). The work on this topic led to the conclusion that with an appropriate concept, modern services based distributed environments can be secured. This concept includes the use of Firewalls and security proxies

Open cloud computing interface : infrastructure

The Open Cloud Computing Interface (OCCI) is a RESTful Protocol and API for all kinds of management tasks. OCCI was originally initiated to create a remote management API for IaaS1 model-based services, allowing for the development of interoperable tools for common tasks including deployment, autonomic scaling and monitoring. It has since evolved into a flexible API with a strong focus on interoperability while still offering a high degree of extensibility. The current release of the Open Cloud Computing Interface is suitable to serve many other models in addition to IaaS, including PaaS and SaaS

Open cloud computing interface in data management-related setups

The Cloud community is a vivid group of people who drive the ideas of Cloud computing into different fields of Information Technology. This demands for standards to ensure interoperability and avoid vendor lock-in. Since such standards need to satisfy many requirements, use cases, and applications, they need to be extremely flexible and adaptive. The Open Cloud Computing Interface (OCCI) family of specifications aims to achieve this goal: originally developed for the deployment of infrastructure Clouds, it can also be used in different service and deployment models. This article will outline the OCCI specifications and demonstrate how they can be used in data management-related setups. Not only can OCCI be easily integrated but it can also be used to deploy data-centric applications (which are secured by SLAs), support data-awareness in scheduling, as well as directly interface with data management tools in a PaaS-based manner. To demonstrate this, three use cases are discussed in this article

A problem solving environment for multidisciplinary coupled simulations in computational grids

This paper describes a software environment for doing multidisciplinary coupled simulations in computational grids using a combination of various existing software tools. The environment consists of the software integration system TENT for setting up, steering and monitoring the simulation, the code coupling library MpCCI for the numerical coupling of simulation codes, and the MPI implementation MPICH-G2 and the Globus Toolkit for running the coupled codes in distributed environments
