 [Azure CNI](https://docs.microsoft.com/en-us/azure/virtual-network/container-networking-overview) is an [open source](https://github.com/Azure/azure-container-networking/blob/master/docs/cni.md) plugin that integrates Kubernetes Pods with an Azure Virtual Network (also known as VNet) providing network performance at par with VMs. Pods can connect to peered VNet and to on-premises over Express Route or site-to-site VPN and are also directly reachable from these networks. Pods can access Azure services, such as storage and SQL, that are protected by Service Endpoints or Private Link. You can use VNet security policies and routing to filter Pod traffic. The plugin assigns VNet IPs to Pods by utilizing a pool of secondary IPs pre-configured on the Network Interface of a Kubernetes node.
 
 Azure CNI is available natively in the [Azure Kubernetes Service (AKS)] (https://docs.microsoft.com/en-us/azure/aks/configure-azure-cni).
