This visual aid would assist with gauging
service consumption in an integrated environment and enable efficient service-oriented ecosystem
capacity planning. ???Service capacity??? identifies the amount of information that a consumer
can request from a service. Capacity strategies are typically carved out ahead of asset deployment
to production environments in order to assist with resource allocation and budgeting challenges.
To better understand the major benefits of the asset utilization diagram, inspect Exhibit 16.8. It
illustrates a service utilization scenario (denoted by the utilized icon), in which the account Web
services cluster (a technological asset) queries a UDDI registry and uses an enterprise service bus
(ESB) to receive customer profile information. The second depicted service??”the customer pro-
file Web service??”employs the very same ESB for posting customer profile data upon subscriber
request.
Exhibit 16.9 identifies the benefits of the major logical architecture reusability perspective
and corresponding best practices.
DISCOVERABILITY PERSPECTIVE
One of the most important aspects of a service-oriented logical architecture is a strategy that
fosters the indirection principle. ???Indirection??? means that consumers and services are dynamically
introduced by a third-party asset. More specifically, the introducing entity enables the discovery
of a published service.
