Object Storage

What is Scaleway Object Storage?

Our scalable object storage service is based on the S3 protocol. S3 is the de facto object storage protocol created by Amazon for its own object storage service. Object Storage officially supports a subset of S3. This cloud-based storage is designed to be highly available and durable.


Is Object Storage available in all Availability Zones?

Object Storage is currently available in our nl-ams (Amsterdam, The Netherlands) Availability Zone and will be available in other geographical locations soon.


How am I billed for Object Storage Service?

During the public beta, which will last four to six weeks, the service is entirely free. Once the service reaches general availability, a notification will be sent to all users with the full pricing information. Pricing starts at €5 and includes:

  • 500GB of storage
  • 500GB of outbound transfer
  • €0.01/GB per additional GB stored
  • €0.02/GB per additional GB transferred

Note: Internal and incoming data transfer is free (e.g., Scaleway instances, Dedibox servers).


How is the Object Storage service calculated?

The Object Storage service is calculated as follows:

  • A monthly fixed price of €5.00 for the Starter Pack which comprises 500GB of transfer and 500GB of storage
  • An hourly rate of €0.00002 for any additional GB of consumed storage, up to 500 storage hours per month (€0.01/GB/month for data stored for a full month)
  • Additional storage is charged in slices of 1GB, which means that if you upload a 3 MB photo and you delete it after 30 minutes, you will be billed for 1GB of data consumption during 1hour

Data transfer towards the Internet is billed at €0.02/GB per GB transferred if you exceed the included transfer amount.


Is there a limitation in number of HTTP requests?

You can make up to 250 requests per second for write and read to a bucket. However, if you need to increase that limit, you can always contact our support team.


How can I access the object storage?

The service is accessible through our console for simple operations.

We provide an S3-compatible API for programmatic access or for usage with any compatible software.


Why is the console limited?

We provide you with a comfortable and integrated UI in the console for convenience.

But it’s not easy to browse infinite storage from the web so we came up with some engineering trade-offs:

  • batch deletion is limited to 1000 objects;
  • empty files are not reported as empty folders.

For all these reasons, we recommend using dedicated tools like s3cmd to manage large data sets.


What kind of data can I store?

You can store any kind of data, in any format (documents, images, videos and much more).


How can I monitor my service?

Once the service reaches general availability, you will be able to monitor your service directly from the Scaleway Console. Metrics such as storage and bandwith usage will help you estimate your bucket consumption.


Which S3 operations are supported?

We currently support a subset of S3 operations. The exhaustive list is available on the S3 Object Storage API page.


How much data can I store?

There is no limit on the total volume of data of a bucket, or the number of objects it can contain. However the bucket might slow down with a very large number of objects.


How many buckets can I create?

You can create up to 100 buckets per user and there is no storage usage limitation per bucket.


I get the message `Bucket already exists`, what is happening?

Bucket names are unique in relation to our whole platform.

The Bucket already exists error message is triggered when the name you intended to use for your bucket is already reserved by another user (or yourself).

When deleting a bucket, its name becomes available again. Anybody can reuse it on a first-come, first-served principle.

Note: We recommend using non-conspicuous names for your buckets.


Is there a limitation in the bucket name?

Bucket names are unique and can consist of the set of the 26 alphabetic characters, a to z, and the 10 Arabic numerals, 0 to 9.


Can I transfer a bucket to another organization?

Bucket ownership is not transferable. A bucket is owned by the account which created it.


Can you recover a bucket deleted by mistake?

Unfortunately, recovering a deleted bucket is not be possible. Also, recovering the objects in a deleted bucket is not possible even if versioning is enabled on that bucket.


Can I use Object Storage as a CDN?

The object storage service was not designed to be used as a CDN: it is not fine-tuned for this kind of usage. We do not recommend it.

You can still use Object Storage as a backend for a CDN. All you need is to put a caching layer on front of it.


How can I access my files via HTTPS?

You can access your files via HTTPS by creating a public link from the control panel. Click on the file name and enable the public link by clicking on the corresponding button.


Can I use Object Storage as a file-system?

You can use Object Storage as a file-system with fuse based project such as s3fs.


Can I change HTTP headers during upload?

Yes, this is allowed with tools like s3cmd, but only cache-control or those prefixed by x-amz-meta.


How can I make an object public?

In order to make an object public, select the object in the console, click Yes to enable the public linking. The URL is displayed automatically.

Public URL

If you upload a file by using the CLI, you can make it public by using the parameter: --acl public-read

Note: You can only make an object public or private (each one at a time). This action cannot be performed on a whole bucket, which is by default private. Allowing public access on a bucket only allows a public listing of the objects that are stored in the bucket.


How can I upload large objects?

Object Storage supports multipart upload. We recommend uploading by chunks, in a limit of 1000 chunks per upload and 5TB per object.


Can I create per-bucket or per-object access token?

What you’re asking for are federated tokens. We don’t support these for the moment as we want to keep tokens simple.


Which credentials do I have to use for the Object Storage?

You can create a token in the Credentials section of the management console. To connect to Object storage, use the Access-Key and Secret-Key displayed during token creation:

Token

Note The Secret-Key is only shown once. Take a note of it and keep it safe. It can’t be recovered if you lose it.


What happens to my data after the public beta?

The public beta will last until November. The official kickoff date will be announced soon.

You can either delete your data before the general availability or continue to use the service where you’ll be charged the regular pricing.


Are my data safe during the public beta?

The Object Storage is designed to provide 99.999% durability of objects over a given year. This durability level corresponds to an average annual expected loss of 0.001% of objects. In addition, the service is covered by SLAs to ensure data availability and durability.

As with any environment, the best practice is to have a backup and to put in place safeguards against malicious or accidental deletion.


What features can I expect in the future?

  • Infrequent Access
  • Cross Region Replication
  • Lambdas for DataManagement
  • Advanced ACL
