What Does Software-Defined Data Center Mean?
A software-defined data center (SDDC) is a type of data repository in which all data center resources and services are provisioned, monitored and managed programmatically.
SDDC host servers reside in the cloud and use virtualization technologies to abstract, pool, deploy and manage compute, network and storage resources.
An important goal of SDDC management is ensure IT infrastructure and operations remain consistent across private data centers and public clouds.
