Overview

The Subscriber Microservices Infrastructure (SMI) Kubernetes (K8s) Cluster Manager allows you to deploy the virtual machines (VMs) – provisioned through the vCenter – on your VMware environment. You can deploy the SMI K8s Cluster Manager either in All-in-one (AIO) or Multimode configurations. In the multimode configuration, the SMI K8s Cluster Manager can manage multiple clusters - with the minimum being three clusters. Also, the in-built Ingress support in K8s allows you to access the K8s cluster over HTTP.

The SMI K8s cluster includes the following VMs:

  • Control Plane – The stateless control plane VMs.

  • ETCD – The database for the K8s metadata. It is separated from the control plane VMs.

  • OAM – The OAM nodes reserved for CEE. It performs monitoring and logging.

  • APP – The SMI applications such as SMF, PCF and so on

The subsequent sections provide more information about the different components in the SMI K8s Cluster Manager.
