Joji Varghese gives us a hand:
In an Azure Kubernetes (AKS) cluster, Pods can access physical storage resources such as disks or volumes using Persistent Volumes (PV). To use these resources, Pods need to make a Persistent Volume Claim (PVC), which requests a specific amount of storage from a storage class. This claim can then be matched to an available Persistent Volume. Azure offers several storage solutions that can be used to provision Persistent Volumes in an AKS cluster.
This article will provide real-world guidance on securely using Container Storage Interface (CSI) drivers to provision Azure File Shares and Azure Blob storage in an AKS cluster.
