The application cloud describes interactions between business entities and the implications on the supporting technical architectures. Interfaces exposing services toward the running applications are provided in the application cloud. The network capabilities are made available to the application developers via defined APIs e.g. basic connectivity management services, transport optimization services, identity services, security services etc. The application cloud can also act as a broker between the application providers and network service providers.
Application cloud architecture
The application cloud consists of applications and the following layers:
- The cloud execution layer can utilize the cloud infrastructure provided by a network service provider, a public cloud provider or be a private cloud
- The facilitation layer has the role to reduce complexity and fragmentation when exposing network assets from many service providers
- The aggregation layer aggregate capabilities from many networks and address the many-to-many problem between a network service provider and application providers
Application cloud in practice
The connected traffic cloud (CTC) transmits traffic information to those on the road, selling the information provided by suppliers via inbuilt billing and business support tools.
The information shared between the vehicles and the traffic operation center includes road conditions, animal/people/obstacle or debris on the road, unprotected accident areas, reduced visibility and exceptional weather conditions.
In this solution, multiple national traffic operation centers are connected via an interchange server, which can route information from the vehicles to the correct national traffic operation centers based on the current location of the vehicle.
Adding new value
A distributed cloud infrastructure creates a unified approach across both centralized and decentralized resources, making optimum use of network connectivity.
This brings with it new value to applications via low latency, scalability, resilience and compliance. Improved latency is one of the major focus areas of 5G – and, to make full use of that development,
all transport networking, computing and storage resources must be optimally placed to form a balanced, end-to-end system.
Crucially, the ability to place data and applications close to networking resources is a major opportunity for operators and application businesses.
