Before Where, a bit of Why?

If

EVERY major

vendor is betting on web services

and

EVERY major application

(ERP, DB, app server, mail

and messaging,

desktop GUI, OS,

programming language, etc.)

is being retooled for

web services

then

The implications are (choose one):

Enormous

Significant

So So

Trivial

But also Why Not!

• Security Issues• Lack of mature authentication and permissioning• Still evolving standards

• Semantic and Namespace Issues• Dynamic marketplaces and relationships are still

a LONG way away.

• Novelty• New technology• Questions of scalability, robustness, IP, etc.

A Matter of Costs and Benefits

• Web Services are not the “be all” and “end all” of integration and communications.

• They are, however, a very important new technology which is clearly going to transform Enterprise IT.

• The key is timing, and deciding “Where to Start”.

Choosing Scope

Business impact and technical risk:

• Day one impact on core systems is a bad idea

• Balance business processes with technical needs

• Even in the beginning, keep the big picture in mind

Choosing Scope

Human Capital and Institutional Momentum:

• Learning by doing• In most enterprises, it is already

happening anyway• WSI is not just a new technology

cycle with a new set of licenses to buy.

Choosing Scope

Bank for the Buck

• A function of costs, benefits, and circumstances

• Even “toy” implementations can go a long way to building understanding and in house expertise

The “Grand Vision” is wrong

Like almost all technologies, WS in the enterprise will roll from the inside out:

• Experimentation on the intranet• Tentative work with trusted partners on the

extranet• Eventual use on the public internet• Different industries already at different stages

Where on the Network?• Within the Enterprise:

– Tentative steps, learning by doing

– Eventual fundamental gains

Within the Enterprise

Private and Trusted Network

Public Networks - The Internet

• Trusted Networks

– Emergence of shared semantics

– Shared understanding of what works and how

things “should” be done

• Public Networks

– Apart from “proof of concept” still a long

way away in most sectors

– Eventually, an immensely rich resource
