Your company has started using Kubernetes for their microservices applications running on containers. To prevent having to manage nodes in VM scale sets and paying for infrastructure which may go unused, they decided to use virtual nodes with managed container instances. With virtual nodes, they can scale up their Kubernetes cluster instantly, which is attractive to the company. You’ve been tasked with helping implement Azure Container Instances with the company’s AKS Cluster.
