Enterprise Services as The Integration Enabler

Enterprise Services as The Integration Enabler

• Greg Wenzel, Booz Allen Hamilton

Net-Centricity is all about the connections
between systems and components

• The two truly transforming things might be in
  information technology and information operation
  and networking connecting things in ways that
  they function totally differently than they had
  previously.
• And if thats possiblethen possibly the
  single-most transforming thing in our force will
  not be a weapon system, but a set of
  interconnections and a substantially enhanced
  capability because of that awareness.
• It can simply be in connectivity. It can be in
  interoperability. It can be in taking things
  that every single one of which exists presently
  and managing them, using them, connecting them,
  arraying them in a way that has a result that is
  transformation.
• - Secretary Rumsfeld, 9 August 2001 Town
  Hall, Washington DC

and the number of possible connections in a
system drive the level of complexity
3
The possible connections required for NCW is
typical of what analysts call an n2 problem
2 interfaces
20 interfaces
42 interfaces
110 interfaces
132 interfaces
156 interfaces
72 interfaces
156 interfaces
where the difficulty climbs exponentially with
each new component n2 problems dont scale
well
4
The term net-centric is intended to position
the network as the source and destination of
information through enterprise services
but effecting this transformation requires
wholesale changes in technology, policy, and
culture

Similar to the DoD Transformation, The Private
Sector has Evolved Its Business Practices to
Gain Greater Business Partner Connections

Independent Operations
Limited Business Connections
Global Business Ops Unanticipated business

SOA has become the next evolution in IT, helping
organizations align their software applications
with business requirements

Making Enterprise Services Real - Service
Oriented Architecture

• Searches metadata catalogs to find data services
• Analyzes metadata search results found
• Pulls selected data based on metadata

DoD Enterprise Applications need to migrate to a
Net-Centric Enterprise
Traditional Enterprise Application
Lightweight Application

• Flexible
• Loosely Coupled
• Agile Development
• rapid,
• lower cost,
• lower risk
• Lower support costs

Visualization

• Integrated
• Tightly Coupled
• Lengthy, High Risk, Costly Development
• Costly Maintenance

Net-Centricity - traditional complex systems give
way to lightweight loosely coupled, services
based applications that reuse pre-deployed core
enterprise wide services
12
Enterprise Services via a SOA enables a new level
of innovation and speed to capability

• Applications need to be developed more quickly
  and at lower cost and risk
• Applications need to be born joint
• Applications must be able to leverage all
  available information
• The cost and risk of traditional System
  Integration activities must cease to be a
  constraint
