What is the Network Economy?

It’s using the network to build your business, serve your customers, beat your competition, and lower costs.

The Developer Problem

● Fragmented “developer” communities

● Information silos● Architectural

complexity● Disparate and

proprietary technologies

What's NeededIntegrated developer view into interfaces for:

– Java apps– XML web services– Legacy C, C++ development– Identity– Portal– Application integration– Tools for all of the above

7 Habits of Open Services Architecting

● Enablement– Enfranchise developers

with interfaces & tools

● Services– Not applications,

no monoliths!

● Evolution– Build value

incrementally

• Federation– Respect value chain

• Assembly– Combine functions

into services

● Virtualization– Distill service &

network functions

● Dynamics– System of growth
