You are migrating an on-premises application to GKE. The application requires a persistent file system that can be read and written to by multiple pods simultaneously across different nodes. Which storage solution should you provision?

In Kubernetes, when multiple pods across different nodes need to read and write to the same volume simultaneously, the volume must support the `ReadWriteMany` (RWX) access mode. Google Cloud Persistent Disks only support `ReadWriteOnce` (or ReadOnlyMany). Filestore (managed NFS) is the correct solution for RWX workloads on GKE.
