What Google Cloud Filestore is

Google Cloud Filestore is a fully managed shared NFS file service for applications requiring persistent storage. It connects with Compute Engine VMs, GKE clusters, Google Cloud VMware Engine, on-premises machines, Cloud Run services, and AI agent fleets or sandboxes. GKE’s CSI driver lets multiple pods share a file system, while Cloud Run can mount an instance as a local directory over NFS. NFSv3 is supported across tiers; NFSv4.1 is available on zonal, regional, and enterprise tiers. Content is encrypted at rest by default, with customer-managed Cloud KMS keys available for listed tiers and backups. NFSv4.1 supports Kerberos authentication, integrity checks, and in-transit encryption; NFSv3 lacks those protections. Filestore offers snapshots, backups, and cross-region replication. Listed capacity reaches 100 TiB, throughput 26 GiB/s, and 920K IOPS. It is paid, with a $300 free-credit trial.
