| POSIX compatibility | The service is POSIX compliant so existing applications, tools and workflows can use it. | The system presents object storage as a mountable file system with POSIX semantics. |
| Release news | Google documented general availability on July 8, 2025 with four performance tiers from 125 to 1,000 MB/s per TiB and capacity up to 8 PB at that time. | Cloud release notes list JuiceFS 5.4.3 on September 22, 2026 with directory healing, replication metrics and mount/cache improvements. |
| Security | Data stored in a Managed Lustre file system is encrypted at rest, and data in transit to and within Google Cloud is encrypted. | JuiceFS supports encryption in transit and at rest; at-rest encryption must be enabled when creating a file system and cannot be enabled later. |
| What it does | Google Cloud Managed Lustre is a fully managed parallel file system aimed at AI and high-performance computing workloads. | JuiceFS is a cloud-oriented distributed POSIX file system that stores file data in object storage and metadata in a separate database. |

In their own words
Google Cloud Managed Lustre
Google Cloud Managed Lustre is a fully managed parallel file system for artificial intelligence and high-performance computing workloads. Documented uses include HPC simulations, modeling and analysis, and machine-learning training and inference. It supports throughput up to 10 TBps and storage capacity up to 84,016,000 GiB (80.1 PiB). POSIX compliance is intended to preserve compatibility with existing applications, tools, and workflows. Instances can mount to Compute Engine virtual machines and Google Kubernetes Engine clusters. The service imports data from and exports data to Cloud Storage, including incremental transfers of new or changed files; only one transfer operation per instance can run at a time. Data is encrypted at rest and in transit to and within Google Cloud. Per-instance policies define maintenance windows and exclusion periods. Capacity is provisioned, and unused provisioned capacity is billed. Pricing is from $0.06/mo; hourly rates vary by month, and monthly charges use the hourly rate and hours in that month. Files can be up to 0.5 PiB, with 20 instances maximum per project. Lustre over TCP is supported, and managed backups are not available.
JuiceFS
JuiceFS is an open-source, cloud-native distributed file system that stores file data in object storage and metadata separately in a metadata engine. It supports POSIX, HDFS, S3, and WebDAV protocols, with storage options including Amazon S3, Google Cloud Storage, Azure Blob Storage, MinIO, Ceph, and HDFS. Documented uses include big data, machine learning, Kubernetes, shared workspaces, and backup. Integrations cover Kubernetes CSI and Hadoop ecosystem components such as Spark, Presto, Hive, Flink, Trino, and StarRocks. JuiceFS offers a self-hosted Community Edition, a managed Cloud Service, and an Enterprise Edition with on-premises, BYOC, and other deployment options. Its downloadable client supports Linux, macOS, and Windows; WSL 2 is recommended for Windows. Encryption in transit and at rest is supported, but at-rest encryption must be enabled when creating a file system and does not cover client-side cached data or file metadata. Community Edition is free; paid plans start at $0.02/mo.
