Select Object Storage API for Secure Browser Direct Uploads

For secure browser direct uploads in private e-commerce, backends should issue short-lived, restricted presigned upload URLs. This approach keeps large files off application servers and limits the utility of leaked URLs. While direct uploads reduce bandwidth, they shift security to CORS and signed-request configurations. To ensure tenant isolation for thumbnails, separate authorization from private read controls and bind object keys to tenant records. Choose storage APIs based on deletion guarantees rather than SDK aesthetics.
