About

Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance.

It supports multiple storage classes, including Standard, Infrequent Access, and Glacier tiers, strong read-after-write consistency, automatic encryption, fine-grained access controls, versioning, cross-region replication, and storage class analysis.

Due to its widespread use, the Amazon S3 API has become the de facto standard for cloud storage compatibility.

Cloudflare R2 is a globally distributed, S3-compatible object storage service designed to store large amounts of unstructured data without charging egress bandwidth fees.

It supports Standard and Infrequent Access storage classes, provides strong durability and security features with bucket tokens and CORS, and includes tools for migration and event notifications that integrate with serverless compute.
