An Analysis of S3-Compatible Object Storage Providers
The Amazon Simple Storage Service (S3) API has become the de facto industry standard for object storage, creating a robust ecosystem of tools, SDKs, and services built around its interface.1 This has spurred the emergence of numerous “S3-compatible” storage providers, each offering a unique value proposition. However, the term “S3-compatible” represents a wide spectrum of functionality, ranging from near-perfect replication of core data operations to significant deficiencies in advanced management and security features. This report provides a detailed comparative analysis of leading S3-compatible providers—Cloudflare R2, Hetzner Object Storage, Vultr Object Storage, and DigitalOcean Spaces—benchmarked against the comprehensive capabilities of AWS S3.
