Event-Driven vs. Service-Oriented Service-Oriented Architecture Interaction • Consumer directs flow • Linear path of execution

Client

Server

• Can not react to new external input once a flow is started

Interface Interface stub proxy

Event-Driven Notification • Sink (recipient) determines flow • Dynamic, parallel, asynchronous flows

Today’s Realities of Enterprise Systems • Systems are: – Too expensive to deploy and maintain – Too complicated and often difficult to use – Too monolithic:

• They were built for the specific purpose and largely ignore the informational needs of the surrounding functional areas. • Not easy to integrate • They are constraining the business efficiency – They are a bottle-neck for more effective business operations

Stipe Fustar: EPCC -- Ullensvang, Norway, June 11, 2007

New Enterprise Systems Trends (1) • New Systems are expected to provide: – A revolutionary application platform that includes: • Standard-based Solutions, • SOA and EDA • Open Source as desired, – Ideally, Systems will be • Dramatically easy to use, • Highly Adaptable; Responsive to the often changing needs • Significantly lower Total Cost of Ownership • Built-to-integrate • Driven by industry standards

Stipe Fustar: EPCC -- Ullensvang, Norway, June 11, 2007

10

New Enterprise Systems Trends (2) • Applications Industry shifts towards Open Standards • Commitment to Standard is becoming a strong sell point • Vendors dedicated to Open Standards are typically Market Leaders • Visionary Companies will Target Traditional Market in non-traditional way – Configuration rather than coding

Stipe Fustar: EPCC -- Ullensvang, Norway, June 11, 2007

11

Next Generation of Energy Systems • Leverages latest Integration Technologies • Returns as Composite Application Framework – Fits into System of Systems Architecture • Presents a new opportunity for vendors’ collaboration – (Pre)-integrated Multi-Vendor Solutions • Forces “built-to-integrate” approach • Requires new standards

SOA and CIM Usage: Role of Patterns

Stipe Fustar: EPCC -- Ullensvang, Norway, June 11, 2007

16

Why Patterns? • Patterns describe architectural constructs / assemblies that work • When used repeatedly a pattern becomes established as best practice. • Patterns can be catalogued • SOA and CIM Usage Patterns should be catalogued – Capture a structured description of SOA and CIM Usage – This will speed up and simplify CIM usage and SOA design and implementation – E.g XML Schema Message Payload generation from UML is a well-established Pattern with several flavors Stipe Fustar: EPCC -- Ullensvang, Norway, June 11, 2007
