Storage Buckets
S3-compatible object storage for files, backups, and static assets.
Pricing
Plans price by the gigabyte stored. Choose a tier based on your capacity needs and expected egress. No per-request charges for standard GET and PUT operations on standard-tier plans.

S3-compatible storage,
no migration needed.
Most teams have workflows built around the S3 API: SDKs, CLI tools, backup agents, and data pipeline connectors. Storage Buckets accepts those same requests without code changes. Your S3 clients point to Tower endpoints and everything else stays the same.
Buckets hold objects from a few bytes to terabytes, with multi-part upload for large files and lifecycle rules to transition or expire objects automatically. Access control policies let you set fine-grained read/write permissions at the bucket or object level.
Pricing is per GB stored with no hidden per-request charges for standard operations. Egress within a region is counted once; external transfer follows the published bandwidth rates.
NVMe storage nodes,
high-throughput fabric.
Objects write to NVMe SSD storage nodes connected over a high-throughput internal fabric. Read latency is consistent whether the object was written ten seconds or ten months ago; there is no tiering delay for standard-tier objects.
Durability comes from erasure coding across multiple drives and nodes rather than simple replication, keeping capacity overhead low while maintaining data integrity across single-drive and multi-node failure scenarios.
The S3-compatible API surface includes PutObject, GetObject, DeleteObject, multi-part upload, presigned URLs, and bucket policies. AWS SDK v2 and v3 clients connect without modification using Tower endpoint and access key credentials.
What you get on Day One
Drop-in S3 compatibility with NVMe-backed durability and fine-grained access control.
S3-compatible API
Drop-in replacement for AWS S3. Works with existing SDKs, CLIs, and integrations. AWS SDK v2/v3 clients connect without modification.
Multi-part uploads
Upload objects of any size using the multi-part API. Store any file type — documents (DOCX, PDF), images, video, archives, and more.
Access control policies
Bucket-level and object-level policies. Public read, private write, or fine-grained rules for each principal. Per-object ACL overrides.
Access without limits
Generate your S3 access key and secret key from the Tower Cloud portal. Connect with any S3-compatible tool or service to manage buckets and objects.

Platform specifications
Values reflect the Storage Buckets product line; exact limits may vary by region and account tier.
- API compatibility
- S3-compatible REST API. PutObject, GetObject, DeleteObject, ListObjects, multi-part upload, presigned URLs, and bucket policies. AWS SDK v2/v3 compatible.
- Durability
- Erasure coding across multiple drives and nodes within a region. Highly durable object storage, engineered to remain available under single-drive and multi-node failure scenarios.
- Storage medium
- NVMe SSD storage nodes on a high-throughput internal fabric. Consistent read/write latency without tiering delays.
- Object sizes
- From 1 byte to multi-terabyte objects via multi-part upload. Maximum single-part upload: 1 GB. Multi-part maximum: 5 TB per object.
- Access control
- Bucket policies with condition blocks. Public-read, authenticated-read, and private ACLs. Per-object ACL overrides.
- Transfer
- Bandwidth within the same region counted once. External egress at published rates. No per-request charges for standard GET/PUT on standard-tier plans.
