This section describes the Tanzu Basic for 5G Core deployment architecture and the placement of its components in the Telco Cloud Platform 5G Core design.
Tanzu Kubernetes management cluster functions as the primary management and operational center for the Tanzu Basic for Core instance. In this management cluster, the cluster API runs to create Tanzu Kubernetes clusters, and you configure the shared and in-cluster services that the clusters use. Shared and in-cluster services are services that run in the Tanzu Kubernetes grid instance to provide authentication and authorization of Tanzu Kubernetes clusters, logging, and ingress control.
Note: The management cluster is designed to operate the platform and manage the life cycle of Tanzu Kubernetes clusters. Do not use the management cluster as a general-purpose compute environment for end-user workloads.
The Tanzu Kubernetes workload cluster is deployed from the Tanzu Kubernetes management cluster. Tanzu Kubernetes clusters can run different versions of Kubernetes, depending on the Cloud Native Network Functions (CNF) workload requirements. Tanzu Kubernetes clusters support multiple types of cloud-native infrastructures (CNIs) for pod-to-pod networking, with Antrea as the default CNI and the vSphere CSI provider for storage by default. When deployed through Telco Cloud Automation, VMware NodeConfig Operator is bundled into every workload cluster to handle the node operating system configuration, performance tuning, and operating system upgrades that are required for various telco CNF workload types for 5G Core. Other networks such as macvlans can be defined in cluster templates and will be mapped to actual networks when the cluster is deployed. Single Root I/O Virtualization (SR-IOV) networks are attached to pods while the NF is instantiated.
