The purpose of the Public Cloud Edge Interface (PCEI) Blueprint family is to specify a set of open APIs for Telco Edge Blueprints to expose towards Public Cloud Service Provider instances at the Edge. As Public Cloud Service Providers deploy Edge instances to better serve their end-users and applications, Telco Edge deployments offer many opportunities for collaboration by exposing their network capabilities to provide value added services.
The need to interface and exchange information through these open APIs will allow competitive offerings for Consumers, Enterprises, and Vertical Industry end-user segments. For instance, open APIs will be provided between Telcos and public cloud edge compute platforms such as Google Cloud Platform (GCP) Anthos, AliCloud Edge Node Service (ENS), AWS Wavelength, Microsoft Azure Edge Zones, Tencent Edge Computing Machine (ECM), to name a few. These APIs are not limited to providing basic connectivity services but will include the ability to deliver predictable data rate, predictable latency, reliability, service insertion, security, AI and RAN analytics, network slicing and more. These capabilities are needed to support a multitude of emerging applications such as AR/VR, Industrial IoT, autonomous vehicles, drones, Industry 4.0 initiatives, Smart Cities, Smart Ports. Other APIs will include exposure to edge orchestration and management, Edge monitoring (KPIs), and more. These open APIs will be the foundation for service and instrumentation APIs when integrating with public cloud development environments and will be defined as part of the implementation. Even though these APIs will be common across all Telco operators, the differentiation will be based on services provided through those APIs.

Business driver | Public Cloud Service Providers are deploying Edge instances to better serve their end-users and applications, A multitude of these applications require close inter-working with Telco Edge deployments to provide predictable latency & throughput, reliability and other telco-grade requirements. The purpose of this blueprint family is to specify a standard set of APIs to expose towards Public Cloud Service Provider instances at the Edge. | |
Business use cases | Telco Edge deployments can provide APIs to support capabilities such as the following
| |
Business Cost - Initial Build Cost Target Objective | The API platform (Gateway, SDK) will be deployed as cloud native containerized technology using Kubernetes. | |
Business Cost – Target Operational Objective | The APIs will be exposed and published to external public cloud service providers and application developers in a secure, controllable, traceable, scalable, and measurable way. | |
Security need | Northbound API platform (Gateway) will provide AAA, ACL, Policy enforcement functions. Southbound APIs that are used to call the core network functions of Telco will follow all the security requirements of 5G/4G core. | |
