Under the hood

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.

Replication

Erasure coding makes durability visible across drives and nodes.

Tower writes objects to NVMe SSD storage nodes on a high-throughput fabric, with erasure coding for single-drive and multi-node failure scenarios.

Capabilities

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

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 on the standard tier.
Object sizes: From 1 byte to multi-terabyte objects via multi-part upload.
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.
