Finally, the logical architecture discipline advocates that architectural solutions
must be driven by strategies, such as asset collaboration, discoverability, a loosely coupled
environment, and interoperability. These topics are discussed in details in Chapter 16.
SERVICE-ORIENTED PHYSICAL ARCHITECTURE
The service-oriented physical architecture is all about physically addressing service-oriented
assets. Physical addressing pertains to mapping software to hardware entities and their addressable
locations in a network. Furthermore, nonfunctional requirements are the major concerns of a
physical architecture environment. This includes run-time environment aspects, such as scalability,
security, availability, deployment, configuration, monitoring, message mediation, and more.
An architecture??™s physical environment also must ensure business continuity and provide the
proper conditions for flawless business execution. This is typically accomplished by monitoring,
mediation, and provisioning activities that take place during the service-oriented life cycle
run-time season.
