Clever Cloud Cellar

Cellar Object Storage

Scale your storage independently of your runtime instances, and get more control over how you grow your infrastructure

Amazon S3 Compatibility

Cellar S3 is compatible with the S3 API, which means that you don't have to change your tooling, scripts, habits... and enjoy the same ecosystem: no lock-in and easy migration.

Plug n' Play

Enjoying a Cellar S3 file storage system on Clever Cloud is a no brainer. In one click, your Cellar Storage is up and ready. Check out the documentation to understand how you can use the AWS S3 SDK to use Clever Cloud Cellar.

High Availability

The Cellar S3 technology offer a distributed file system management. It means more concurrent requests and better availability of your assets on your apps. We have launched our Cellar S3 more than 3 years ago and it never crashed. So far, we can proudly display a 100% SLA. You can also host Cellar on your own infrastructure using Clever Cloud On-Premises.

Large Capacities

You can store files from a few KB to several TB. You can step uploads and downloads for large files or just because you need to.


You don't have to config anything. We set the Cellars so you can enjoy the most secured configurations.

Pre-signed URLs

No more I/O management and accesses. You can use pre-signed URLs as paths of your assets in your templating. Ideal for profile photos for example. You can also upload with pre-signed URLs directly from your browser. It's less code, less time, less debug.


You can manage rights and accesses on both files and folders through your Cellar S3 client. It's less code to write.

Awesome Support

Any question? Our friendly support team is here to help you. Via chat or email, feel free to reach out.

Sliding Price Scale

Our price grid is calculated on both outbound bandwidth and storage space. The more you need, the less you pay your TB of bandwidth or storage.

Free Plan

Even if our pricing is interesting for large players, we did not forget those who want to try our Cellar S3 ; a free plan is available for your first 100 MB of files. Just like the big Cellars, but smaller.


No credit card needed.
