Sensoria Bibliography Site Architecture and Behaviour Analysis for Engineering Software Modes
Howard Foster
abstract:
Engineering services in the framework of an Service-
Oriented Architecture (SOA) is complex and open to mistakes
if a rigorous approach is not taken. Combining SOA
with features to support dynamic service discovery, management
and binding, increase the chances that an architecture
configuration has been incorrectly specified. To facilitate
service engineers designing and implementing service
systems we introduced the notion of Service Modes,
that at design time provide an abstraction of service configurations
given particular requirements for runtime. This
paper describes how behaviour protocols are included in
these configurations and how properties of combined architecture
and behaviour models can be used to perform some
useful analysis to assure dynamic service architecture configurations
are safer and more resilient to incompatibilities.
The modelling and analysis techniques are supported by an
implementation in the LTSA WS-Engineer, a comprehensive
integrated tool suite for verification and validation of service
compositions.
