S3-compatible object storage providers 2026: capabilities compared
Azure Blob Storage and Google Cloud Storage use their own native APIs; Google offers an XML API with S3 interoperability, recorded here as partial. Providers whose object storage is S3-compatible can be used with standard S3 tools and SDKs.
