Foreseen 5G verticals hold the promise of being true value-added services, hence bringing significant income to their respective providers. However, the nature of these verticals are very demanding in terms of both economic and technical requirements, such as multi-operator cooperation, end-to-end quality assurance, and the unified orchestration of network and cloud resources. Existing systems fall short of satisfying these requirements, but emerging network softwarization and resource virtualization technologies, such as SDN and NFV, show promise for being key enablers in this context. In this article, we introduce the 5G Exchange (5GEx) concept that builds on SDN and NFV, and facilitates the provisioning of multi-operator 5G services by means of inter-operator management and orchestration of virtualized network, compute, and storage resources. We present potential 5GEx use cases, conceptual architecture, and value proposition. We also outline open research questions on how to exchange information in such a coopetitive environment, and provide an outlook on the impact of 5GEx on a network service provider's business and operation.

This will allow end-to-end network and service elements to mix in multi-vendor, heterogeneous technology and resource environments. Market fragmentation has resulted in a multitude of network operators each focused on different countries and regions. This makes it difficult to create infrastructure services spanning multiple countries, such as virtual connectivity or compute resources, as no single operator has a footprint everywhere.
\r\n\r\n5GEx aims to enable collaboration between operators, regarding 5G infrastructure services, with the view to introducing unification via NFV/SDN compatible multi-domain orchestration by producing:
\r\n\r\nSuch 5G infrastructure services will provide a crucial role in making 5G happen as they provide the foundation of all cloud and networking services. 5GEx aims to enable, through operator collaboration, a unified European infrastructure service market integrating multiple operators and technologies, where service provisioning is fast and automated and which results in stronger economy via economies of scale.
