Service inventory and service layers

26

The service inventory is the central place

to store all available services which are part

of the scope of the SOA solution

Service layers are used to organize services

In the service inventory. The reusability differs

per service layer

Task service

Entity service

Utility service


SOA applied at an utility company

27

This utility company delivers water to more than 700.00 households in the Netherlands. Customers can consume different online services on the website, like water consumption, payment services, etc. This company wants to be able to adapt to changes in the market and introduce new online services with a short time-to-market.

Reducing the maintenance costs is a secondary goal for this organization.

Situation

ComplicationThere was a lack of knowledge on service oriented architecture and not a clear vision how to implement this. The current IT environment and governance was not able to support a service oriented architecture.

Solution

Accenture and Avanade helped this company by developing a clear vision for their business and IT. We provided technical consultant who implemented this vision and we also maintain the solution. We introduced an integration department which is responsible for applying principles and patterns related to SOA.
