The Control plane creates and manages the Virtual Network in the case of Kubenet. The Control Plane assigns IP Address to the Pods that do not fall in the IP Range of the Cluster Virtual Network. This aspect makes the Pods as not accessible from outside the Cluster. However, using Azure CNI, you can directly access the Pod.
We utilize heavily cloud services, so experience on AWS, Azure, or Google Cloud is seen as a big plus - Expertise as Kubernetes CNI networks experience

However, using Azure CNI, you can directly access the Pod. Let us explore Kubenet Virtual Network for Azure Kubernetes Service in this article and reserve Azure CNI Virtual Networking for the next article. iptables in Azure CNI. So we’ve seen how iptables handles traffic for pods in kubenet, so lets run through the same path for an Azure CNI node. Go ahead and ssh to one of your Azure CNI cluster nodes and take a look at the high level rules like we did for kubenet, and then we’ll walk through at a lower level. Setup We’ve been through the kubenet implementation, and now we’re on to Azure CNI. Lets start by creating an Azure CNI based AKS cluster. We’ve already created the Vnet and Subnets, so all we need to do is create the cluster. Notice a few changes in the ‘az aks create’ command below.
Azure Container Networking Interface (CNI) networking. The AKS cluster is connected to existing virtual network resources and configurations. Kubenet (basic) networking. The kubenet networking option is the default configuration for AKS cluster creation. With kubenet: Nodes receive an IP address from the Azure virtual network subnet.
I wonder how many people prefer Kubenet in a managed environment. Nodes. Unlike EKS, none of the offerings has a builtin support for bare metal nodes.
Network plugin/CNI: Amazon VPC Container Network Interface (CNI) Azure CNI or kubenet: kubenet (default) Calico (added for Network Policies) kubenet (default) External CNIs can added; Kubernetes RBAC: Required. Immutable after cluster creation. Enabled by default. Immutable after cluster creation. Enabled by default. Mutable after cluster creation. Supported since 2017
For container networking, EKS has Amazon VPC CNI while AKS has Azure CNI. If you’re after a little more options AKS supports Kubenet too. Many people prefer Kubenet in a managed environment. Nodes. EKS offers support for bare metal nodes.
This is one of the fundamental ways that Azure Kubernetes Service with the kubenet plugin differs from AKS with Azure CNI. Node to node traffic is directed by an Azure Route table. Before we look at the route table, one thing to know is that traffic between pods does not go through SNAT (Source NAT). I don't want to paint myself in a corner here regarding kubenet, is there anything missing from my list? Looking at the many options for CNI's however, coupled with the setup of Kubernetes, configuring everything, etc it seems like a big pain to sort out what I should go with if I move away from kubenet. Kubenet networking - Network resources are typically created and configured as the AKS cluster is deployed.

Azure CNI networking. Deploys into a virtual network and uses the Azure CNI Kubernetes plugin. Pods receive individual IPs that can route to other network services or on-premises resources. Kubenet networking. Azure manages the virtual network resources as the cluster is deployed and uses the kubenet Kubernetes plugin.
Apps Infra. So, which networking option should you choose for your Azure Kubernetes Service deployment in production I think this document should be updated to reflect the Azure CNI / Kubenet. Maximum nodes per cluster with Virtual Machine Scale Sets and Standard Load Balancer SKU. With Kubenet = 400 nodes / AKS cluster With Azure CNI = 1000 nodes / AKS cluster To help, I created this short 9-minute video that explains how Kubernetes networking on Azure works, using examples to illustrate, including Kubenet, Azure CNI, and Calico. In the video you’ll learn: Some essential background on Azure networking and Kubernetes pod networking. Why Use CNI. Kubernetes default networking provider, kubenet, is a simple network plugin that works with various cloud providers.
