“Indigo”: Services And The Future Of Distributed ApplicationsDon BoxArchitectMicrosoft Corporationhttp://www.gotdotnet.com/team/dboxemail here – uh you don’t want to send me mail

Session Code: WSV 201

The Software Ecosystem

The inevitability of connected applications

3

The Object Ecosystem

One metaphor to rule them all

4

The Service Ecosystem

Respecting the boundaries of others

5

The Service-Oriented Model

Services, Clients, Systems

6

Tenet: Boundaries are Explicit

Developers opt-in to exposing service-based functionality

7

Tenet: Services are autonomous

Independent deployment, versioning, and security

8

Tenet: Share Schema, not Class

Integration based on message formats and exchange patterns, not classes and objects

9

Tenet: Policy-based compatibility

Service compatibility based on policy assertions using stable global names
