Sovereign object storage
All the power of S3, without the dependency
100% S3-compatible API
Your AWS SDK applications work without modification. Change the endpoint, keep your code.
End-to-end encryption
SSE-S3, SSE-KMS and SSE-C supported. Keys under French jurisdiction via KMIP/HSM.
99.999999999999% durability
Erasure coding with 1.5x overhead (vs 3x with replication). Your data survives entire disk failures.
WORM / Object Lock
Immutable storage for financial and regulatory compliance. Cohasset Associates certified.
Versioning and lifecycle
Native versioning, retention policies, automatic transitions between storage classes.
Multi-datacenter active-active
Synchronous replication between French datacenters. Zero interruption in case of site failure.

Full S3 compatibility
Migrate without rewriting a single line of code
Supported operations: Buckets, Objects, Multipart Upload, Versioning, Lifecycle Policies, IAM, ACL, CORS, Presigned URLs.
Your AWS SDK applications (Python boto3, JS aws-sdk, Go, Java) work by simply changing the endpoint.
# Python boto3
import boto3
s3 = boto3.client('s3',
endpoint_url='https://s3.france-nuage.fr',
aws_access_key_id='YOUR_KEY',
aws_secret_access_key='YOUR_SECRET'
)
Limitations: no native SNS/SQS/Lambda triggers. Alternative available: webhooks and Kafka.
Frequently asked questions
Is Ceph storage truly S3-compatible? +
Yes. RadosGW implements the S3 API natively. AWS SDKs (boto3, aws-sdk) work by simply changing the endpoint URL. No code modification is needed.
Is my data encrypted? +
Yes, three encryption modes are available: SSE-S3 (server-managed keys), SSE-KMS (keys managed via a KMS under French jurisdiction), and SSE-C (customer-provided keys). In-transit encryption is ensured by TLS 1.3.
How do I migrate from AWS S3? +
Use rclone, aws s3 sync, or any S3-compatible tool pointing to our endpoint. Migration can be done incrementally without service interruption.
What is the data durability? +
Erasure coding ensures 15 nines durability (99.999999999999%). Data is distributed across multiple disks and nodes, with automatic reconstruction in case of hardware failure.
