7 illustrates a typical mission
perspective architecture. The plug-and-play and the orchestration and choreography technical
architecture frameworks enable rapid development of mission supporting systems and services.
Plug-and-Play Architectures. The most common architectural approach that can efficiently
tackle the business architecture mission perspective requirements is the Microkernel pattern.11
This method addresses changing mission requirements and enables quick expansion of future
application and service development. Furthermore, Microkernel software architecture technologies
can also improve communication between services and consumers in interoperable computing
environments as well as contribute to service portability and adaptability. This pattern is based
on plug-and-play technical frameworks that treat service-oriented software, such as subsystems,
services, or components as pluggable entities to enable business agility and reduce time-to-market.

Other portable options are introduced by SOA intermediaries. They serve as connecting
brokers between services and consumers and perform a variety of duties, such as data transformation,
protocol translation, and security augmentation. Enterprise architecture integration (EAI)
technologies also contribute to architecture portability.
