SDDC is a collective term often used in IT when working with
virtualization technology. With SDDCs, the data center
infrastructure is virtualized, and with this virtualization, the
compute, storage, and network infrastructure components are
also virtualized.
With virtualization, it is possible to abstract the physical
hardware into virtual pools and efficiently use your resources.

Software-defined data center components
Because the data center components are now software-based
(Figure 1-1), the configuration is agile, and parts and services
can be provisioned faster than ever before with a physical data
center infrastructure.
Clouds
The SDDC is typically used in a cloud, which is generally one
or multiple SDDCs.
A private cloud is referred to as an SDDC infrastructure that is
typically hosted on-premise (or on-site), and a public cloud is
related to an SDDC infrastructure that is generally hosted
off-premise (or off-site) somewhere remote, whether in a rented
data center facility or a full, hosted Infrastructure as a Service
(IaaS) offering.
