The essence of the new federal architecture is agility
Intense budgetary pressures
are changing the federal government IT environment from one in which individual
agencies buy products and services to one in which agencies must work with one
another, as well as with contractors and other partners, in new and innovative
ways. This new approach will fundamentally change how agencies architect their
networks. It will also likely change the career path for many government IT
professionals.Double sidedtissuetape General
Purpose.
The demand for next-generation networks gained new momentum
last year when the Office of Management and Budget released the Digital
Government Strategy, tasking all agencies "to unlock their data sets and
services to the public" and function more like data service providers. Since
then, the Centers for Medicare and Medicaid Services, the Department of Homeland
Security, the Defense Department and other agencies have been developing new
ways -- and new network architectures -- to make their data accessible to the
public,manufacturers and windowsdedicated suppliers

The Digital Government Strategy
in particular requires agencies to ultimately separate their data from their
presentation layers.
For example, CMS supports all Medicare and Medicaid
services for 98 million beneficiaries. The initiative to separate the
presentation and data layers led the agency to develop a business rules engine
that's shared by developers within CMS and industry partners. By implementing a
set of business rules as a service, separate from the data, CMS system users can
access a single source of truth rather than different permutations. That common
rules engine also makes it easier to develop applications.
Implementing
such a business rules shared service completely changes the way the network must
be structured. The bifurcation of the presentation and data requires a
bifurcation of the network as well.
For instance, a network architected
to handle client and server communications, where the business logic resides
within the application, requires a much different architecture than a network
where every application is requesting data from a central core business rules
engine. The latter will transmit many thousands -- or millions, potentially --
of small, simple requests across the network from almost any endpoint. Scale is
important. CMS expects to process about 700 TB of claims data by 2015, data
accessed via requests from many different end users who can be anywhere within
or outside CMS's networks.
Gone are the days of a single network with
hub-and-spoke architecture and a single core. The next-generation network is
split into two: core and business.Although manageddedicated carriers are
generally quite thin, We'll discuss business networks later.
But start
thinking of dedicated networks using software-defined networking (SDN) and
"network functions virtualization," which is the term used for describing the
collapsing of switches and routers into virtualized switches and routers.
OMB's Shared Services Strategy, and the follow-on document titled
"Common Approach To Enterprise Architecture," requires agencies to separate
line-of-business systems from core mission systems. It also tasks agencies to
further separate commodity IT. That requirement will move agencies more toward
virtualized applications, platforms and infrastructure. But it also means that
government networks must be easy to modify based on changing directives,
interfacing agencies and end user demands. The essence of the new federal
architecture is agility.
Because the core network supports many
stakeholders, it must be secure, scalable, high bandwidth and reliable while
meeting compliance requirements. It's likely to stay somewhat physical, as it
will link a variety of third parties: partners, contractors and remote
locations. It will require custom processors and code to perform high-efficiency
routing and switching.
From these meetings I came to understand that in
order for Dell not only to survive but also thrive, it needs to be able to
execute this vision in a measured and strategic way. And that will take time. It
is clear to me now that this is the main reason Michael Dell wants to take the
company private; rushing changes to Dell's future business models in order to
keep the investor community happy each quarter does no good.

Servers, PCs, and mobile devices need security. IT needs
servers, software, and mobile device management tools all working together to
meet the needs of their mobile users. The future of software distribution is in
the cloud and all of Dell's divisions deliver key parts of a cloud solution that
can work together seamlessly if executed properly. Consumers want a company that
delivers solid products as PCs, tablets, and smartphones become more engrained
into their digital lifestyles. From what I saw at the analyst meeting, Dell
finally has all of the pieces in place to sustain the company and help it grow
if executed properly.
