Scality accessors are software APIs that communicate with an application and enable storage virtualization. Scality supports multiple accessors such as RESTful APIs which allow for the development of other purpose-built accessors. Scality is the developer of RING, a software platform enabling cloud storage to easily scale up to exabytes using commodity server hardware with direct attached storage. Scality is typically used for private clouds (especially backup, video and file sharing, media archive, healthcare, genomics and geophysics), for public clouds (StaaS), for SaaS applications (webmail) and for Web 2.0 services. Public documentation of the API is not available.
