Cluster Networking

Cluster networking is highly-coupled container-to-container, pod-to-pod, pod-to-service, or external-to-service communication.

Cluster networking takes advantage of parallel processing of computing devices.

Kubernetes uses third-party projects for cluster networking:

• ACI
• Antrea
• AWS VPC CNI for Kubernetes
• Azure CNI for Kubernetes
• Calico
• Cilium
• CNI-Genie from Huawei
• cni-ipvlan-vpc-k8s
• Coil
• Contiv-VPP
• Contrail / Tungsten Fabric
• DANM
• Flannel
• Hybridnet
• Jaguar
• k-vswitch
• Knitter
• Kube-OVN
• Kube-router
• L2 networks and linux bridging
• Multus (a Multi Network plugin)
• OVN4NFV-K8s-Plugin (OVN based CNI controller & plugin)
• NSX-T
• OVN (Open Virtual Networking)
• Weave Net from Weaveworks

We preconfigure cluster networking with Cilium for VPC networks.
