The
Page 4

“Get them interested, Get them excited, Get them involved“
.

What can we learn from the success of the WWW? It created a free market where people could
communicate freely without any central instance that controls its use. Now it is time for
companies to adopt this free market concept of the WWW to shape an
Enterpri
se 2.0
. SOA is
the technology paradigm to make the new
Enterprise

2.0 possible.

Why can a pool party be more important for the success of your
SOA

and
Enterprise 2.0

strategy than a proper management plan? What can we learn from the success of the iPhone
for our next mission?
It is all about emotion, excitement and trust
.

SOA

is made from an odd couple: services and architecture. A new architecture is needed to
bring down the
obstacles

that currently embarrass a harmonic playing together of software of
10

dif
ferent legacy.
SOA

is also the starting point to bring down the emotional walls between the
classical IT department and the users who try benefitting from the technology. With growing
complexity it

becomes obvious that we move t
owards a free market exchange for services,
replacing the silos and isolated integrated applications of the 1990ties.
SOA

will eventually
transform our computer landscape into
market
of loosely interacting services
based on
individual and ad hoc service co
ntracts.

By no later than 2015 we will live in a world where most computers can interact freely with
each others. Programs will run no longer on a
dedicated

server but find a place in a giant
computing cloud where it is executed. Companies who prepare ear
ly for this brave new
world will be the big winners.

20

This book will be
indispensable
for
the

IT
professionals charged

with the privilege
of
being
allowed to promote
SOA

for their enterprise.

Cape
Enterprise 2.0

In today’s business environment change is inevitable. Heightened competition, mergers
and steadily more complex technologies and products around every corner have increased
the pressure on companies to beco
me more agile. By 2015 enterprise computing will be

primarily

handled via internet based, outsourced web services making classical centralized
computing a niche market. The Service
-
Oriented Architecture (SOA) is deemed to be the
strategic approach to fulfi
l these ambitions and you cannot but see it as inevitable for the
future.

We call this the
Enterprise 2.0
.

1.1

The IT of the
Enterprise 2.0

So what will
change when SOA and
Enterprise 2.0

come to life
? SOA will bring you away
from centrally controlled
silo
-
structured

software application landscapes that live in
isolated and fortified habitats and are governed by a small “aristocracy” called IT
department. SOA will distribute break down software into small component that are then
assembled into “business

processes”. The components will eventually be spread across the
internet and may be owned by a multitude of different domains. In the end our IT will
transform into a Marketplace of freely combinable internal and external components that
will be offered t
o other applications as services. No longer will the potential requestors of a
little change of his most important software need to fall on their knees and beg for
10

assistance; they will be able to choose easily from a range of providers
who offer the
funct
ionality as a service that can be easily plugged into your existing infrastructure
.
Service vendors will no longer first scrutinise their willingness to do the requested change
but rather they will woo in competition to get the mandate to render the servic
e.

1.1.1

When will
Enterprise 2.0

happen?

Let us fix a year: 2015. By 2015 the face of the Information Technology as it is exercised
within an enterprise will have changed dramatically

and companies that ignore this
development will eventually stay behind.

E
nterprise computing will be handled via
network
-
based,
outsourced services
that can be both located internally or
somewhere in the wide internet and hence
mak
e

classical
centralized computing a niche market.

We believe 2015 is a
safe

bet

when we look the time ray of th
e

development of
enterprise IT
:

10



1980 our enterprises were supported by mainframe
applications;



1990 the personal computer was the regular work p
lace
in a somewhat modern office;



1995 the PCs were already connected through company
wide networks that allowed exchange of data and emails
with ease; and the PCs became rich clients with
intelligent frontends that connected to powerful ERP
backend appli
cations like SAP, BAAN,
PeopleSoft
, JD
Edwards,
Great Plains

or
Navision


20



2000 the internet and WWW was a familiar addition to
the internal
computing

assets;



2005 the Service Oriented Architecture of the WWW
allowed social and interactive computing



2010
we will have full virtualization of computing
centres

where the physical hardware can be anywhere in the
range of the internet


1.1.2

WWW is the role model for
Enterprise 2.0

Building a complex and dynamic society like the
Enterprise 2.0

cannot be planned in det
ail.
30

Nothing complex and successful on earth has followed a master plan but it has always been
the result of a steady and ongoing improvement of an already existing good thing.

Enterprise 2.0

will also not be a
genius

design built on a green
field but it will be the result of adopting successful concepts
from other domains to make the existing better.


Enterprise 2.0

and SOA will not change everything but will
improve many things.”

While enterprises are still trying to get control over their
farms of enterprise application we realize the dramatic
cha
nged already our working style of every day through the
40

Enterprises will be run be a
blend of internal and external
services

Enterprise 2.0

and SOA will not
change
everything

but will
improve many things

The success of WWW is based
on top of a small number of
applications

service offers of the WWW. Let us understand the core
application
s that build the backbone of the internet success:




Google

It

We no longer “look up information”, we
rather

Google

it;



Amazon

It

if
we need a book we no longer stroll through the book
mart but we look it up in “Amazon”;



Letters

to the webitor

we no longer write letters to the editor, but we comment
10

the article directly on the respective web page;



Flickr your holiday

we
no longer invi
te people to a diorama

show evening to
present our latest holiday pictures but we
rather post
them in a
Photo

Blog like flickr.com;



Collaborate not meet

students do no longer meet under in the afternoon to do
their homework, they rather meet virtually in t
he
collaboration workspace where all work on the same
document at the same time, chat via their internet
20

messenger and share our desktop with Mikogo;



Share your solution

companies do no longer solve technical issues in private
but they open a virtual forum

in the internet where both
questions and answers are recorded for eternity


W
e can expect
that by
2015 the achievements of the internet
fully
have also been
adopted
throughout
modern enterprises.
And those
companies that would not keep pace with this
development are most likely to suffer dramatically in terms
30

of efficiency and ability to react on the quicker and quicker
changing world.

Companies that do not adopt
the
Enterprise 2.0

will starve

1.1.3

What will happen in
Enterprise 2.0
?

But let us make the time warp to the year 2015.
In a reversal of the trends of the beginning
of the
Millennium

where we saw a tendency towards a concentration of IT service
providers we will now have
application service provisioning
distributed amongst a large
number of smaller but specialized makers and vendors.


Many successful companies struggle heavily with the
challenge to align the speed with what their business changes
with the
creepiness

of IT change management. These
companies do not lack the technical excellence but rather the
10

organizational m
alfunctions and the stiffness of the current
applications.

The reason for the inflexibility of many ERP software blacks
can be tracked down to the high degree of interwovenness of
features and functional
ity. Changes of a small bit in one place
may have immediate impact in several hundred other places.
The ERP blocks need either be broken into parts or frozen
and encapsulated like an oyster encapsulates the bacillus in a
precious
pearl
.

Ch
a
nging the ERP dinosaurs
will become more and mo
re
difficult

ERP hybrids host to many
interwoven functionalities

: ERP dinosaurs will be frozen and encapsulated like a
pearl


We shall see a dramatic change in the self
-
understanding of
IT. Software will be a large
symphony
built from small
independent
ly

acting and maintained components

driven by
an orchestra that rearranges the components in harmony
.

The centralized ERP systems that had dominated the 1990
and early years of the millennium

will turn into dinosaurs.
They will not disappear but will,
lose

their

current status as
leading information system and continue to run as powerful
expert legacy systems.

10


1.1.4

Is
SOA
the solution for
Enterprise 2.0
?

Now that we can observe that the inflexibi
lity in their IT has led to severe losses in the total
business we need to look out for the strategy that combines cost effectiveness and agility in
change management. What we look for is breaking down all our technical application
hybrids into slick funct
ional components and trading them on an internal marketplace.
That is where SOA comes in the picture.

The new IT will be based on the ability to react quickly on
change: the time from recei
ving a request for a new feature
and its implementation will be expected to be as low as a
20

couple

of days only. That will not leave room for centralized
and
clumsy

tankers. Those organisation that are small
enough to react and move like a speedboat will take the
dominant market share of service catering.

Reacting quickly on changes is only possibility if the area and
component
s that are meant to be changed are small enough
entities that the impact of taking them out and replacing
them is a clearly arranged task.

That is what happens in our human lives when we work in a
marketplace where c
lients and servicemen can freely deal
30

with each
other’s

under the constraints of a low
-
impact and
clearly defined set of market rules.

Software will be a large
symphony of small parts and
components

Legacy applications will turn
into expert components

IT will need to react quickly on
business requirements and
changes

Agility requires small cells to
work on

Marketplaces are the role
model of SOA

The nicest thing with SOA is that it does not demand
omnipotence. SOA implementation is an
offer. SOA is an
answer to the special challenges when a large number of
independent objects interact. SOA gives
answers

to the
demand that changes need to be done right away while
guaranteeing safety and compliance with global rules.

SOA is not the only way to achieve this goal but it is our belief
that SOA is the by far best approach to it.

Just compare it
with economics: market economics seems to be the
fittest

concept for large economies, but plan
-
driven economies are
10

also a possibility, even if
it appears to be
less efficient.
Those
who believe that IT can stay as it is today will not need SOA
or at least will not see the need for it.


1.1.5

What are the elements o
f
Enterprise 2.0




1.1.6

Web 2.0 and Social Computing

Web 2.0 stands for the ability to interactively change content that you see on the web.
When this is possible other peers connected to the internet can immediately view your
20

changes.

Once you are able to make changes of your web content
visible to others in real
-
time you are in possession of a
platform that allows real
-
time communication. No longer will
you make changes on your documents offline and
send them
over via email and wait until a revision comes back. Now you
may change the original document and your reviewer can
even see what and where you change.

You add the possibility to make a
phone conversation via
internet phone like Skype, show a video image of your
30

workplace and even share your desktop across the internet.
What you created is a forum (
Latin

word for market) where
you can interact and share your assets with chosen friends
and

colleagues
. What you created is a
social web
.

This social web

is possible through a number of stunningly
simple but powerful utilities, mostl
y of them available free of
charge for everyone with a WWW capable computer.
They

are the
killer applications that gave the social web the
current momentum to make it fly, fly, fly …

SOA is an offer, a good offer

SOA is not the only s
olution, but
the most efficient one

Web 2.0 made the WWW an

interactive communication
platform

Interactivity allows creation of
a forum for collaboration

The social web

is driven by
small number of applications

The www killer applications

The success story of the WWW is the role mode
l for our future
enterprise. While

perusing the
most successful killer applications of the Web we have a starting point to shape our enterprise.


Let us understand

the most important components of the
WWW to learn what makes them so attractive and whether
we can use their idea or technology to shape a better work
place in our enterprise.

Google

10

Google has become the synonym for search engine. Finding
information that otherwise cannot be found has been
entered our all
-
day language: to
Google
.

Search engines are also attractive for enterprises although
they are currently not wide spread. There may

be search
engines for the local intranet but searching across the diverse
multi
-
channel data sources is still a rarity. We need to search
the document archives, data from ERP systems, emails and
also data
stored

locally on the PCs of our co
-
workers.

Yahoo
!

Yahoo! stands for
cataloguing

and
inventorying

the WWW.
Although Yahoo! With their partner
AltaVista

made search
engines popular, Yahoo! believed to long that internet search
can only be handled by classifying information by humans.
This is a lesson to l
earn for enterprises, since their belief in
directories and classification systems is still highly ranked.

Amazon

Amazon is the synonym for e
-
Commerce. Their popularity
and success once triggered the e
-
commerce hype at the
10

beginning of the m
illennium when it appeared that every
company wanted to prefix their name with a miniscule “e”.

Web shops will soon play a role in intranets as well. There will
be a lot of things to trade. Think of an assembly line that
consumes parts from other cost
-
cen
tres
. Procuring the
components is a web shop task. And once you have a web
shop you may also invite your outsourced vendors to hook
onto it with their offers and procurement data.

Blogging

Blogging


correctly Web
-
Logging


is the possibil
ity that
20

everybody with an internet account can write articles and
newsletters for everybody to see.

Blogging in the intranet is a great way to share information
with other co
-
workers. One author proposes a concept and
others are able to comment online. T
oday, this happens
mainly via email.

Chat rooms


Chat rooms

are a place where people in different places of
the world can meet electronically and have conversations.
Other than telephones,
chat rooms

are silent and can
30

protocol the conv
ersation.

Skype

Skype is the synonym for internet messaging and internet
telephony. The fact that it can
save

a lot of money in
telephone costs made even less proactive companies
adopting Skype as telephone replacement for long
-
distance

calls.

Web CMS (Portals)

A content management system (CMS) is a place where a
closed group of user can easily post information and
40

documents to share with other in a common look and feel.

In the internet such CMS are becoming now the standards for
web si
tes. It is also the domain of the open source
communities. Popular free CMS are Drupal, Typo3, Plone,
Alfresco which are all good for large professional sites and
also Joomla as a starter tool for good looking small private
web sites.

Wikipedia

Wiki is another

for the change in our society under

Wikipedia is based on the power of masses. It proved that a
large number of non
-
trusted
individuals

necessarily produce
high
-
quality when they can collaborate freely with each
others.

Wiki
-
style content management is an absolute must for
enterp
rises. However, it will also be the touch
-
stone where
we can see if an enterprise is mature enough for the modern
SOA based
Enterprise 2.0
. Wiki can only work when
20

companies are ready to allow every employee to touch even
sensitive content at any time with
out restrictions; only then
the power of masses can blossom.

Share points


Central data
share points

have been around for long in form
of file servers and are the only WWW component that is
probably far better spread in enterprises than in the WWW
itself.
