Modern applications are increasingly built using microservices running in Kubernetes (K8s) containers. To extend vDefend's security posture into this containerized world, VMware utilizes Antrea .
Antrea is a Kubernetes-native Container Network Interface (CNI) plugin. It is explicitly designed to handle networking and security at the container Pod layer. It leverages Open vSwitch (OVS) as its high-performance data plane on the Kubernetes worker nodes.
Its two primary capabilities are:
Pod Connectivity: Routing IP traffic between different pods across the K8s cluster.
Network Policy Enforcement: Implementing K8s NetworkPolicies to micro-segment container traffic, which seamlessly integrates with the overarching vDefend Distributed Firewall UI. It does not perform public cloud macro-routing (Options A/D) and does not use legacy Nexus switches (Option C).
