Modern, cloud-first application development, at least on Azure, has become almost dependent on Kubernetes. Technologies such as Virtual Kubelets, the AKS (Azure Kubernetes Service), and the Azure Service Fabric Mesh are key to building scalable distributed applications on Azure, using containers to deploy and manage microservices.
