This document describes the use of Public Cloud Edge Interface (PCEI) implemented based on Edge Multi-Cluster Orchestrator (EMCO) for deployment of Public Cloud Edge (PCE) Apps from multiple clouds (Azure and AWS), deployment of a 3rd-Party Edge (3PE) App (an implementation of ETSI MEC Location API App), as well as the end-to-end operation of the deployed PCE Apps using simulated Low Power Wide Area (LPWA) IoT client.

Functional Roles

Developers

Individuals/entities that:

• Create the PCE/3PE Apps
• Provision services in Public Clouds (PCC)
  • Note that valid Public Cloud subscriptions/accounts are required
• Package PCE/3PE Apps using Helm Charts

End-to-End Validation Environment

...

For performing Steps 1 and 2 please refer to the PCEI R4 Installation Guide.

Provisioning PCEI Orchestration Infrastructure (EMCO)

Please refer to the PCEI R4 Installation Guide to deploy EMCO and Edge K8S Clusters.

...

To register the two Edge K8S Clusters created during PCEI installation (refer to PCEI R4 Installation Guide), the cluster configuration files need to be copied from the corresponding VMs to the machine that is used to  access EMCO UI. Please make sure that the ssh key used to access the VMs is present on the machine that where the cluster config files are being copied to. The example below assumes that the cluster config files are copied to the Host Server used to deploy EMCO and Edge Cluster VMs. Alternatively, the ssh key and the config files could be copied to a laptop.

...

Clone Azure IoT Edge from github:

NOTE: Due to Azure IoT Edge on K8S being in preview stage, please use the below URL to clone the Helm charts:

https://github.com/Azure/iotedge/tree/release/1.1-k8s-preview

git clone https://github.com/Azure/iotedge

cd iotedge/kubernetes/charts/
mkdir azureiotedge1
cp -a edge-kubernetes/. azureiotedge1/
cd azureiotedge1

Click on "+ Add App" and add the "awsggc1" app. Make sure to use the "awsggc1" name to match the app tar file name without the extension:

// Oleg Berzin, is this figure same as the previous figure? - Tina Tsou (Deactivated)

Define the AWS GGC app by adding the App tar filr and the Profile tar file:
