Historically, every
massive Scale Up evokes a future Scale Out of capabilities in the IT industry.
Mainframes to Unix
systems, Unix systems to x86
Centralized to
distributed to centralized, etc.
Inevitably, a
technology advancement forces a state change in the mechanism or requirement
that filters how the industry chooses to deal with that event.
Today the industry
is taking massive advantage of Cloud capabilities that are changing how
computing services are acquired and managed.
This advantage is, in no small part, arrived at by new commoditization
levels of access to computing capability.
It can be turned on and off at will and pay only for the portion of
resource used. It is a Utility with
respect to IDC's 3rd Platform concepts and equates directly to a financial
disruption to the traditional model of application delivery.
On the horizon, are
things like IoT (Internet of Things, that have the potential to take significant advantage of new streams of data
made available by sensors for, well, anything.
Other areas,
including the enormous growth in content and data delivery are creating the
need for mega Data Centers which are scaling up to meet the demand of the
under-layer of scale out of the compute necessary to run this industry. This scale up is associated directly with the
pressure to continue the cost reduction of the service enable-ment of Cloud and
Virtualization, with some financial benefit to more traditional 2nd Platform
capabilities. (See
Scale Up to the mega Data Center)
When content
delivery and IOT bandwidth and/or latency requirements overrun the data
transport capabilities of the mega Data Center, two things based on the history
of this industry are almost assured to change for the 3rd Platform Utility
consumption of computing resource.
1 - IOT Sensor data
ingestion will be driven back to the edge, or closest point of creation
2 - Content Delivery
will be driven back to the edge, or closest point of consumption
The consequence of
this may be instrumental in the next major change in the development of the
Data Center industry.
One possible model
for this change is a hub and spoke model for compute resource consumption. In this model, the mega Data Center becomes
the hub for the majority of bandwidth or latency insensitive applications and
the spoke provides all of the edge services for bandwidth and latency sensitive
requirements.
The compute utility
will have to assume a role that not only spans availability zones for
application redundancy, but edge zones for the more sensitive application
requirements.
Where it could get
really interesting, if the power utilities started to provide co-location
(edge) services for mega Data Centers.
The combination could be extremely compelling, especially if the power
utility were able to achieve re-classification of the edge service data center as an IT
resource rather than a typical power consumption entity (human facility).
Consider the
ramifications of a co-location hosting facility within the boundaries of an
electrical substation.
Re-classification of
the edge service to an IT resource could eliminate much of the expense of power
redundancy for the co-location facility, with minor modifications of the existing power delivery rules. It could be dual fed from two active power sources. As an example, a redundant power generation facility would not be
required. As another example, a UPS
would not be required. As a third
example, a power transfer switch would not be required.
Furthermore, it could provide an immediate step down to direct electrical bus
in the IT resource facility. In the future,
direct step from AC power to DC in the IT resource to get at the extra ~8%
efficiency.
AND
Power distribution
aligns pretty darn nice with edge service data distribution facilities. If the power Utility was worth its salt, it
either has a fiber network already established OR it has partnered with someone
to lay fiber in the right of way.
This would place compute, subsequently creation and consumption, within milliseconds of the majority of the population and nearly all of the industries at fiber bandwidth.
