Software-defined storage (SDS) is an emerging storage technology for the data center, IaaS, PaaS and SaaS. It will (key word "will") allow applications to define, manipulate, expand, shrink and protect storage based on application policies in an on-demand basis. The multi-tenant cloud market is driving SDS. The currently available storage systems closest to being SDS are cloud storage systems based on object storage technology.

SDS will apply to SSDs in the same way it applies to HDDs: The performance of the media is just one factor in policy-driven, on-demand flexibility.
