Here, architecture abstractions
are discovered that describe the technological environment. It is simply a matter of generalizing
technology needs to facilitate an implementation plan for the future production landscape. These

EXHIBIT 1.14 SERVICE ARCHITECTURE MODELING DISCIPLINE PROCESS
Modeling Environments 21
architecture imperatives may include service-oriented assets, such as third-party vendor products,
existing services, middleware, and software platforms.
Logical Architecture Modeling. The other important driving aspect of the service-oriented
architecture modeling discipline is a logical architecture perspective in which asset utilization,
consumption, reusability, interoperability, and loose coupling best practices are being addressed.
This process is chiefly concerned with the logical aspect of the production environment, in
which service-oriented assets (services, legacy applications, language platforms, and middleware)
must coexist and collaborate. Therefore, an asset utilization diagram provides detailed interaction
between the deployed software packages and further elaborates on consumption and reusability
requirements of a logical architecture.
MODELING ENVIRONMENTS
A modeling environment is not necessarily a physical location where the service-oriented modeling
process takes place.
