SeaweedFS S3 Origin Storage

SeaweedFS S3 Origin Storage is available in the NetActuate Marketplace as a one-click, open-source appliance you can deploy into any NetActuate PoP. S3-compatible object storage as a streaming origin near every edge. It is grouped under the Storage category.

What It Does​

SeaweedFS is an open-source distributed storage system that stores billions of small and large files with constant-time (O(1)) disk access, then layers an optional Filer for a POSIX-style directory tree and a full S3-compatible API on top of its blob store. It scales horizontally with minimal operational friction and ships web UIs for the master, the filer, and a modern admin console.

Key features

  • O(1) disk-seek blob storage optimized for billions of small and large files
  • S3-compatible API, plus Filer with POSIX, FUSE mount, WebDAV, and Hadoop compatibility
  • Master web UI (default port 9333) showing cluster topology, volumes, and stats
  • Filer web UI (default port 8888) for browsing, uploading, and managing files
  • Modern admin UI for cluster management, buckets, users, policies, and maintenance
  • Erasure coding for warm storage plus configurable replication for durability
  • Cross-cluster active-active replication and cloud-tiering to remote object stores
  • Optional encryption, TTL/auto-expiry, and tiered hot/warm data placement

Use cases

  • Self-hosted, S3-compatible object storage as a MinIO or cloud-storage alternative
  • Storing and serving huge volumes of images, media, or user uploads at low latency
  • Backend blob store for JuiceFS, backups, data lakes, and Iceberg tables
  • Geo-distributed storage with active-active replication across regions

Why run it on the NetActuate edge Serving objects from a PoP near users cuts download latency and origin egress for media and asset delivery. Cross-cluster replication places read replicas close to each audience while keeping a consistent global namespace, and edge volume servers absorb read-heavy traffic locally so spikes are handled near the source.

Best for: S3 origin, Object storage, Media assets.

Using the Appliance​

Deploy in minutes

  1. Connect. SSH as ubuntu@YOUR_VM_IP with your deploy password or SSH key.
  2. Check the cluster. Open the master UI at http://YOUR_VM_IP:9333/ to see volumes and topology.
  3. Use the S3 API. Point any S3 client at http://YOUR_VM_IP:8333 with the access key and secret key you supplied at deploy.
  4. Create a bucket. For example aws --endpoint-url http://YOUR_VM_IP:8333 s3 mb s3://media then upload objects as usual.
