 ### :material-folder-network: Configure a shared-home volume
 * All of the Data Center products require a shared network filesystem if they are to be operated in multi-node clusters. If no shared filesystem is available, the products can only be operated in single-node configuration.
-* Some cloud based options for a shared filesystem include [AWS EFS](https://aws.amazon.com/efs/){.external} and [Azure Files](https://docs.microsoft.com/en-us/azure/storage/files/storage-files-introduction){.external}. You can also stand up your own NFS

+* Due to the high performance requirements on IO operations, Bitbucket needs a dedicated NFS server providing persistence for a shared home. For this reason we don't recommend that you use cloud managed storage services such as AWS EFS. See [more details](../examples/storage/nfs/NFS.md#bitbucket-data-center-and-nfs).
 * The logical representation of the chosen storage type within Kubernetes can be defined as `PersistentVolumes` with an associated `PersistentVolumeClaims` in a `ReadWriteMany (RWX)` access mode.
 * For more information about volumes see the [Volumes section of the configuration guide](CONFIGURATION.md#volumes).
