Such an asset presentation model is vital to describing a
service-oriented ecosystem in which service-oriented assets, such as services, consumers, legacy
applications, and their supporting technologies interface and coexist. It is a tool that can help in
crafting a service-oriented integration strategy. The asset utilization diagram is composed of three
major components, which are discussed in the sections that follow.
TECHNOLOGY FOUNDATION SECTION. The technology foundation section is made up of
backbone technologies that empower the service-oriented ecosystem. These are typically the
underpinning service-oriented software entities that support the technological environment, such
as middleware components that enable service-oriented assets to communicate on a network,
and supporting platforms, such as language frameworks. These technological assets are used
to establish a logical architecture foundation. This formation is akin to a pyramid structure in
which each layer supports the layer above. Therefore, the very bottom levels of the logical
architectural foundation section should consist of imperative software and hardware assets that
carry out the technological environment??™s supporting tasks. Exhibit 16.2 illustrates this idea.
