Google Cloud Managed Lustre vs LucidLink

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.

LucidLink streams files from cloud storage into a shared filespace, so collaborators can work with large files without downloading or syncing entire files. When an application opens a file, it streams only the data that application needs. The service mounts like a local drive and works with Adobe Creative Cloud, AutoCAD, Figma and Final Cut. LucidLink Connect can bring storage such as Google Drive, Dropbox, SharePoint and S3 into a unified filespace. Its iOS and Android apps support uploading, browsing, previewing and sharing. The company says files use end-to-end AES-256 encryption, with customers controlling keys under a zero-knowledge model. Security options include SAML 2.0 SSO, SCIM provisioning, folder permissions and real-time access enforcement; audit logs and snapshots support tracking and recovery. Starter costs $7.00 per billed member/month and is limited to 10 members and 1 TB. Business is listed at $3,227.00 per month, limited to 25 members and described as suitable for up to 10 TB. A 30-day trial is available.
