S3-Compatible Storage
Also known as: S3互換ストレージ / Object Storage / オブジェクトストレージ
The collective term for object storage services that implement the Amazon S3 API. Examples include Cloudflare R2, Backblaze B2, and MinIO. The shared API enables vendor-agnostic code using the same AWS S3 SDKs.
Overview
S3-compatible storage lets you use the AWS SDK while swapping providers. Cloudflare R2 offers zero egress fees and Vercel Edge Storage integration, making it especially attractive for edge-focused projects.
