Services. Often, the underlying complexities of the physical and virtualized environments are abstracted from the consumer (as in PaaS and SaaS today).
£SDDC extends this operational model by further refining and expanding upon the three traditional delivery models of Cloud; that is, infrastructure, platform and software as a service (IaaS, PaaS and SaaS respectively).
SDDC isn’t a panacea either. It doesn’t simplify the complexity or management of the physical data center environment. The physical data center will still be the major underlying component for any virtualized, Cloud or SDDC solution, regardless of vendor.
The provider, carrier or intermediary will still have all of the complexity of managing and operating a physical data center -- as they do today. An SDDC, however, may make the management more efficient.

Realizing an SDDC To realize an SDDC, data center resources, such as compute, network, and storage, need to be expressed as software. They also need to have certain characteristics, such as multi-tenancy; rapid resource provisioning; elastic scaling; policy-driven resource management; shared infrastructure; instrumentation; and self-service, accounting, and auditing.
This ultimately entails a programmable infrastructure that enables valuable resources to be automatically cataloged, commissioned, decommissioned, repurposed, and repositioned.
Lastly, there needs to be the desire to do this, and to drive vendors, standards bodies and developers of the myriad services that make up a data center to do this.
A recent Forrester Market Overview on Midrange Storage (
http://www.forrester.com/ Market+Overview+Midrange+Storage/
fulltext/-/E-res110681) noted: “When asked whether a software defined datacenter was part of their strategic planning, 58% of respondents disagreed or completed disagreed, with 24% somewhat agreeing. Only 17% completely agreed or agreed.”
A large number, albeit still a minority, think that SDDC is strategic in the year ahead. For a concept that’s only a few years old, it’s a significant number. It will be interesting to see, as the DMTF finalizes its report on SDDC, how this changes in the next few years.
