Setup Azure Kubernetes Private Clusters with API Server Vnet Integration

Many companies strive to extend their data centers to the cloud to take advantage of the cloud providers’ enormous resource capacities. For some this is a short-term expansion due to business peak seasons, for others, it is a permanent need. Regardless, they would want to maintain the privacy and security that their private clouds and data centers provide. This means they would like to avoid exposure to the public internet as much as possible. In this video, we will discuss hybrid and cross-premises cloud concepts and how Azure’s private networks provide network isolation on the Azure cloud. In this video, we will help a fictitious Acme Corporation set up a private Kubernetes AKS cluster in Azure without exposing the API server or Kubernetes services’ DNS name/IP addresses. We will introduce the “Azure Kubernetes Service cluster with API Server VNet Integration” and VPN gateways to achieve our task. We will also discuss some of Azure’s fundamental concepts such as tenants, subscriptions, resource groups, and management groups.
