Google Cloud Managed Lustre vs ObjectiveFS

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.

ObjectiveFS is a shared distributed POSIX file system for persistent storage across cloud instances, laptops, containers, and office servers. It runs on Linux and macOS and can be self-hosted. The software runs on customer machines and connects directly to object stores through the S3 API, without storage clusters or metadata servers. Multiple machines can read and write the same filesystem, with updates visible across them. Supported targets include Amazon S3, Google Cloud Storage, Azure Blob Storage, IBM Cloud Object Storage, Oracle Cloud, DigitalOcean Spaces, Scaleway, Wasabi, Ceph, MinIO, NetApp StorageGRID, Hitachi Content Platform, and S3-compatible stores. Data is encrypted locally with a customer-known key and remains encrypted in transit and at rest; checksums verify integrity. Automatic and checkpoint snapshots can be mounted read-only. Personal costs $99 a month and includes 3 instances, up to 50 instances, 5TB storage, and unlimited filesystems. A 14-day trial is available, but there is no free plan. Object-store charges are billed separately. ObjectiveFS does not run natively on Windows, though a Linux machine can export it through NFS or Samba.
