The 5 Lies People Love to TellAbout the Software Defined Datacenter
It looks like a box! It can’t be software
defined!

Software Defined
“You can’t define the software-defined-datacenter – it’s just a buzzword like cloud!”
-The Slashdot Crowd
Lie #1
Defining the Software Defined
Datacenter
A pooled-resource model for datacenter management that eliminates silos of compute, storage, and networking created around individual applications
…with software-based provisioning, control, and reporting…that is vendor agnostic to the underlying compute, storage, and networking resources…and de-couples application provisioning from the physical hardware it is using…turning the datacenter into a resource that can be programmed like software
So what really matters in the
SDDC?
Vendor-neutral datacenter management tools that support a wide range of underlying systems
Extremely simple management and comprehensive APIs for all infrastructure elements
Software and systems that are designed for multi-tenancy
Underlying infrastructure that can deliver a consistent level of resources and performance with Guaranteed QoS
“Everyone needs a Software Defined Data Center”
-Anyone selling SDDC
Lie #2
Most companies don’t even need their own “data
center” anymore
SDDC really only matters at scale Scale where the efficiency of pooled
infrastructure matters Scale where the up-front complexity of systems
integration pays off in operational savings Scale where the rate of infrastructure change is
a barrier to progress …and…
If you aren’t at scale, you probably shouldn’t be running your own infrastructure anyway
Host it with someone who does(and they probably have a SDDC)
Define “not at scale”: Today: Less than 300 virtual machines Soon: Less than 3000
“SDDC is just virtualization. We already do that.”
-Overworked IT Departments
Lie #3
Virtualization was just the start of the
SDDC
Virtualization showed the power of a pooled model for compute
Don’t need to dedicated servers to each application
Rapid deployment of new “virtual” machines VM sizing not tied to physical hardware
…but it didn’t fundamentally change the management paradigm
Infrastructure still under administrator control Primarily a manual provisioning model
…and it really only covered compute Storage systems and networking still managed
separately Multiple toolsets and teams required to get
anything done
“You can’t be ‘software-defined’ if you include hardware.”
-People trying to sell storage system software
Lie #4
“Software-defined” is
about management,
not a sales model
You can’t have a software defined datacenter without hardware
Modern storage systems are virtually all “software-based”, whether sold as software or bundled with hardware
The storage system should be part of the data plane, not the control plane
The storage system is the resource to be managed, not the resource manager
But where do you draw the line for advanced functionality like snapshots, replication, deduplication, and backup?
“Converged infrastructure is required for the SDDC.”
-CI Vendors
Lie #5
Converged infrastructure
can simplify building a
SDDC, but it’s neither
necessary nor sufficient
Solutions that integrate compute, storage, networking hardware with smart management software can be part of a SDDC
…but it’s not required…nor does it mean that every converged infrastructure offering is a SDDC
And there are trade-offs that run counter to the SDDC
Vendor lock-in to specific infrastructure elements?
Inability to integrate best-of-breed
Many advantages of pre-built converged infrastructure disappear at larger scales
