Software-Defined Data Center.
May also be called software-defined datacenter (SDD) or virtual data center. Software-defined data center (SDDC) is the phrase used to refer to a data center where all infrastructure is virtualized and delivered as a service.
Control of the data center is fully automated by software, meaning hardware configuration is maintained through intelligent software systems. This is in contrast to traditional data centers where the infrastructure is typically defined by hardware and devices.
Software-defined data centers are considered by many to be the next step in the evolution of virtualization and cloud computing as it provides a solution to support both legacy enterprise applications and new cloud computing services.

In the simplest terms, IT achieves a lot more with a lot less, at dramatically lower cost.

2) Network Virtualization vs. Software-Defined Networking (SDN) -
As
with server virtualization before it, network virtualization is a
transformative architecture from VMware that overcomes previous
limitations to deliver unprecedented performance, flexibility and
economics.
In contrast to software-defined networking (SDN), in which hardware remains the driving force, VMware technology truly decouples network resources from underlying hardware. Virtualization principles are applied to physical network infrastructure, abstracting network services to create a flexible pool of transport capacity that can be allocated, utilized and repurposed on demand.
In a close analogy to the virtual machine, a virtual network is a software container that presents logical network components—logical switches, routers, firewalls, load balancers, VPNs and more—to connected workloads. These virtual networks are programmatically created, provisioned and managed, with the underlying physical network serving as a simple packet-forwarding backplane. Network and security services are allocated to each VM according to its needs, and stay attached to it as the VM moves among hosts in the dynamic virtualized environment. - See more at: http://www.vmware.com/software-defined-datacenter/networking-security.html#sthash.WPpi6YAC.dpuf

3)Software-Defined Storage (SDS)
Software-Defined
Storage (SDS) is the vision that storage services are dynamically
created and delivered per VM and controlled by policy. VMware’s SDS
model shifts the operational model of storage from the bottoms-up
array-centric approach of today’s storage to a tops-down VM-centric
model. As a result storage services are precisely aligned with
application requirements. - See more at:

4)Unified Data Center Management Software
The
fully virtualized data center is automated and managed by intelligent,
policy-based data center management software, vastly simplifying
governance and operations. A single, unified management platform lets
you centrally monitor and administer all applications across physical
geographies, heterogeneous infrastructure and hybrid clouds. You can
deploy and manage workloads in physical, virtual and cloud environments
with a unified management experience. IT becomes agile, elastic and
responsive to a degree never before possible. - See more at:
