Recommendation
Cloudflare R2 and Amazon S3 are both object-storage options. Choose based on existing architecture, expected object count, requests, access controls and actual data transfer.
Cost model
Compute monthly storage, read/write request counts and outbound transfer. Include operations, retention and region restrictions; do not compare only a headline per-GB price.

Editorial note
Examples are starting points, not production security audits. Confirm dependencies, versions and pricing using linked vendor documentation.
