VMware introduced the vision for the software-defined data center (SDDC) in 2012. It provides the infrastructure that enables the software-driven data center. The SDDC is the VMware cloud architecture in which all pillars of the data center, such as compute, storage, networks, and associated services are virtualized and automated. This document focuses on one aspect of the VMware SDDC, the storage pillar, and specifically discusses how vSAN fits into this vision for service providers.
