Last month we reported that there were 2,904
separately funded FY12 IT budgets. Many of these would be set up to operate their
own and incompatible networking, storage, server, operating systems, middleware
or control commands.
Silos have a long history in DoD. They often
stretch for decades. During a long development time they create distinctive
formats that keep reducing the interoperability with other solutions. The
enclosed tabulation of some long-term projects accounts for 18% of total IT
spending, This illustrates up to 35 years during which program managers and contractors keep
developing silo-specific features.
DoD cannot afford supporting the continuous stream
of maintenance costs associated with decades long software development cycles.
As an immediate remedy it is now in a position to acquire software that will accelerate
the adoption Information-as-an-Infrastructure (IaaS) solutions. There are now
hundreds of cloud services firms that offer such technologies, though they
range from proprietary (such as Amazon, Microsoft and Google) to open source
(such as VMare) solutions.
Instead of keeping up separate infrastructures for
each silo, DoD can start migrating to a much smaller number of infrastructures.
This can be done by evolutionary migration. Each legacy silo applications can
be “encapsulated” into a virtual package so that it can now run on its own
virtual computer.
Such virtual computers can take advantage of pools
of shared servers, of disk memory and of a shared communications environment.
Capacity utilization will then increase. Security policies will be enforceable
across an entire range of virtual computers. The conversion to IaaS services
will become one of the principal means for delivering the projected reductions
in the number of data centers that is presently receiving widespread attention.
Though a reduction in the number of data centers
will result in cuts in expenses for brick and mortar facilities as well as for
managerial overhead, the major gains will come from the pooling of processing
capacity for better utilization and for sharing of disk memories that will
offer reductions in the required disk space. Hard to quantify gains will come,
however, from the consolidation of security services. Formerly costly security enforcement
means, such as expert manpower and specialized security appliances will now be
available for more consistent control of security measures.
Instead of elongating project schedules for
individual silos, DoD should be able evolve in very short order to a much
smaller number of enterprise infrastructures, each subject to central controls
for assuring data and communications interoperability. Existing silo budgets
for separate infrastructures will have to curtail further spending on
infrastructure to fund a much smaller number of pooled enterprise solutions. Such
migration could start in the next fiscal year by shifting processing of parts
of some applications from legacy silos to a limited number of commercial public
clouds from where they would support as “hybrid cloud” solutions without users
seeing much of a difference. After sufficient experience is gained, parts of
such solutions could then relocate into DoD owned and operated private clouds.
DoD will have to find a method for extracting
funds from increasingly obsolete legacy programs to Joint enterprise projects
that offer a shared infrastructure. Such a move will allow DoD components to
concentrate on applications, but without their prohibitively expensive
custom-made infrastructures.
The original 1992 intent for creating DISA was to
make it a shared provider of enterprise services. The fiscal mechanism for
delivering such services has been long available as working capital funds that
can be used to charge individual users not as allocations of fixed costs, but
as a fee for services used. Transaction-based pricing will have to be
instituted in this new environment so that components can make competitive
comparisons as they shifts cloud workloads between cloud services in a hybrid
environment.
