A marketing phrase that serves to group a variety of software-defined computing technologies into one overarching moniker. The umbrella of Software-Defined Everything (SDE) technologies includes, among other terms, software-defined networking (SDN), software-defined computing, software-defined data centers (SDDC), software-defined storage (SDS) and software-defined storage networks.
With Software-Defined Everything, the computing infrastructure is virtualized and delivered as a service. In a Software-Defined Everything environment, management and control of the networking, storage and/or data center infrastructure is automated by intelligent software rather than by the hardware components of the infrastructure.
SDE can also refer to a similar term, Software-Defined Environment, which is a buzzword created by IBM for its vision of a more cohesive software-defined everything world.
