Cluster networking is a core part of K8s and is responsible for communication between containers, between Pods, between Pods and Services, and between external systems and Services. Kubernetes Container Network Interface (K8s CNI for short) is a set of specifications defined by CNCF for writing CNI addons to provide container networking and security functions for K8s clusters.
AKE supports using the open-source container network solution Calico and its CNI, or Arcfra Integrated CNI (AIC for short), which is independently developed by Arcfra, in workload clusters. AKE also supports separating the management network from the application network and configuring multiple NICs for Pods.
