Secure file uploads using presigned URLs involve generating a temporary, signed endpoint clients use to upload files directly to storage. This backend storage Skill provides endpoints to generate presigned URLs for single, multiple, and multipart file uploads.

File visibility levels control access to stored objects. This Skill manages public, private, protected, and shared visibility states, applying corresponding access methods to ensure secure, scalable file handling across your distributed backend services.

Multipart upload splits large media files into smaller segments uploaded independently before final assembly. This Skill satisfies backend endpoints for complete multipart upload flows, ensuring scalable and reliable transfers for large images, documents, and media.

Yes, registering and updating file metadata is handled through REST endpoints. This Skill provides backend operations for metadata registration, file listing, retrieval, updates, and deletes to maintain accurate records of stored files.

A CDN is not strictly required for protected file access via presigned URLs, though it enhances delivery. This Skill handles protected visibility directly through backend API access methods, ensuring secure retrieval without mandatory CDN dependencies.

Multipart upload should be used for large files instead of single presigned URLs to ensure reliability and scalability. This Skill supports both methods, allowing you to handle large media and documents by splitting transfers into manageable segments.
