Established in 2010 and based in Nantes, Clever Cloud provides a fully managed PaaS environment for deploying applications and services. Its Cellar product is an S3-compatible object storage service for storing unstructured data (images, backups, logs, etc.). Cellar is built on the same European infrastructure as Clever Cloud’s other services, meaning all data is stored in Clever Cloud’s own French data centers for GDPR compliance. The Clever Cloud platform is ISO/IEC 27001 certified and HDS-certified for sensitive data, and it guarantees 100% data sovereignty (no data shared outside France). The service supports automated scalability, high availability, and offers integrations (via an S3 API) with common tools – all managed through Clever Cloud’s web console or CLI, emphasizing ease of use and security.
