•Drains itself again
•Heat the air to dry the dishes off, if the user has
selected that setting
•Monitor to make sure everything is running
properly
•Time to regulate the length of each cycle.
•Sense if the water level gets too high and activate
the draining function to keep the dishwasher from
overflowing.
•Sense to detect the dirtiness of the water coming
off the dishes. When the water is clear enough, the
dishwasher knows the dishes are clean

Undesirable IT Development
Desirable IT Development
IT developers—
 Continue to create large / complicated core
applications, but with associated Services.
 Produce and expose Services that enable access to
data and functionality important to IT consumers.
IT consumers—
 Envision interesting applications and instead of
producing a laundry list of requirements, they
develop prototypes and applications using simple
tools to aggregate and consume Services.
Traditional Interfaces Deliver
Limited Access to Core Data

With access to data, consumers

Functional leaders
define application

Consumers create
alternative interfaces
Many applications are
developed by an almost

Mashups
Not “build it and they will come,” but rather
“they will come and help build it.”
Examples:
 1800TravelBooking.com




Combines Google Maps, Google Spreadsheets, and Geocoder with hotel
cost information
Zillow iPhone Application

Combines VirtualEarth and Zillow


13,600 suppliers are aggregated to offer last minute travel deals.
Consume Web Service Interfaces provided by travel suppliers.

Consume Web Service Interface from Google and Twitter

Abstraction Facilitates Innovation

When you expose Web Services you are providing an API






It should be intuitive
It should be safe
It should be documented
It should be supported
It should be exposed through “the registry”
There may be hierarchies of Services


Data Services
Core application Services


Aggregated Services



GMU
Not all Services may be exposed to everyone
No Service Silos



AIM, PeopleSoft, etc.
Services must be architected from the top down
Not necessary to have management and provider services


EGAB has been active in recommending
policy around all aspects of SOA
Registry is in place
President’s Council has approved and is
anticipating broad availability and use
A Community of Excellence (CoE) is being
organized
Many presentations, like this, have been given
across campus – the campus is excited and
waiting!
What I need and Expect

I need all of you to hear, understand, and
internalize this vision

We won’t be successful until my vision is shared by
those who work here
I need those who understand and share this
vision, to evangelize it
I need the vision implemented


Help us find solutions to the problems we are sure
to face
Don’t deliver only what I am asking for, deliver
what I want! Go the second and third mile
Summary


Catch the vision
Share the vision
Implement the vision
Find solutions to problems that are in our way
Use me to remove road blocks, obtain
resources, and clarify direction
This is our chance to make IT significantly better
on campus,
Let’s do it together!
