Introduction and Purpose of the PCEI Architecture
The purpose of 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.

And in northbound, it provides RESTFUL APIs and SDKs to be called and integrated by public clouds.
PCEI Reference Architecture and Interface Reference Points
The PCEI Enabler is expected to provide Multi-Domain Interworking capabilities between the following domains:
...
The following figure shows high-level relationships between the domains:
The Data Center Facility (DCF) Domain. The DCF Domain includes Data Center physical facilities that provide the physical location and the power / space infrastructure for other domains and their respective functions.
The Interconnection of Core and Edge (ICE) Domain. The ICE Domain includes the physical and logical interconnection and networking capabilities that provide connectivity between other domains and their respective functions.
The Mobile Network Operator (MNO) Domain. The MNO Domain contains all Access and Core Network Functions necessary for signalling and user plane capabilities to allow for mobile device connectivity. These functions include the Radio Access Network (RAN), including the 5G New RAN (5GNR), Packet Core, including the Virtualized Evolved Packet Core (vEPC) and the 5G Core (5GC).
The Public Cloud Core (PCC) Domain. The PCC Domain includes all IaaS/PaaS functions that are provided by the Public Clouds to their customers. These include Virtual Private Cloud and Public/Private Networking capabilities.
The Public Cloud Edge (PCE) Domain. The PCE Domain includes the PCC Domain functions that are instantiated in the DCF Domain locations that are positioned closer (in terms of geographical proximity) to the functions of the MNO Domain. In general, the PCE functions are expected to be managed from the PCC functions.
The 3rd party Edge (3PE) Domain. The 3PE domain is in principle similar to the PCE Domain, with a distinction that the 3PE functions may be provided by 3rd parties (with respect to the MNOs and Public Clouds) as stand-alone instances of Edge Computing resources/applications.
The PCEI Reference Architecture and the Interface Reference Points (IRP) are shown in the figure below. Note the this figure also provides a component level layer view of the PCEI Architecture:
