The Edge Multi Cloud Orchestrator (EMCO) - also previously known as ONAP4K8S version 2 - is an application orchestrator designed to deploy geo-distributed appliations across multiple edge/cloust kubernetes clusters.

See the following articles for background on the requirements and architectural principles:

Architecture Overview

The following diagram depicts a high level overview of the EMCO architecture.

  • Cluster Registration Controller registers clusters by cluster owners
  • Network Configuration Management handles creation/management of virtual and provider networks
  • Distributed Application Scheduler provides simplified, and extensible placement
  • Hardware Platform Aware Controller enables scheduling with auto-discovery of platform features/ capabilities
  • Distributed Cloud Manager presents a single logical cloud from multiple edges
  • Secure Mesh Controller auto-configures both service mesh (ISTIO) and security policy (NAT, firewall)
  • Secure WAN Controller automates secure overlays across edge groups
  • Resource Syncronizer manages instantiation of resources to clusters
  • Monitoring covers distributed application

The following diagram illustrates  additional details of the EMCO architecture.

The following sections will describe specific components in greater detail.

Getting Started - EMCO Installation

The EMCO microservices can be installed into a Kubernetes cluster.

See here for the helm chart:

To install with kubectl, see here:

The clusters to which EMCO deploys resources can be any Kubernetes cluster.  However,  because EMCO provides built in OVN4K8S networking support, clusters with OVN4K*S installed is required if that networking option is needed.

The KUD project provides one method for installing a cluster that has these required features:

Also, for status monitoring, EMCO utilizes the monitor microservice and associated CRD.  

Current files needed to setup and install are here:  (see the file)
