Amazon Simple Storage Service (Amazon S3) provides a set of APIs that enable applications to access object storage. With the popularity of S3 object storage, more storage vendors are implementing their own object-storage engines with S3-compatible APIs. However, some Amazon S3 APIs are designed specifically for Amazon Web Services (AWS), with example services including life cycle management, charging, and analytics. Third-party S3-compatible storage usually implements a subset of Amazon S3 official APIs to enable object access.
Starting with Dell EMC™ OneFS™ version 9.0, Dell PowerScale™ introduces the capability of data access by exposing the compatible S3 APIs. To facilitate administration and application deployment with the OneFS S3 implementation, this document shows how OneFS S3 API compatibility compares with the latest version of the Amazon S3 API.
