Taxonomy of Services

In one of my previous posts, I had blogged about creating a taxonomy of services using functional categorization.
For e.g. Entity Services, Task/Activity Services, Process Services and Infrastructure services.

But services can also be categorized from different perspectives such as layers or intent of use. For e.g.
Categorization based on Service Layer:

1. Business Services: Represent high level business functions that define an enterprise.
2. Application Services: Application specific and usually will be aggregated in a composite service at the business level.
3. Infrastructure Services: Utility functions that deliver cross cutting functions.

Categorization based on scope:
1. Enterprise Services: Multiple LOBs use the service.
2. Domain Services: Applicable only within a LOB.
3. Application Services: Local to the App Level.
