为什么采用面向服务的体系架构 ?
A Service Oriented Architecture enables flexible connectivity of
applications or resources by
Representing every application or resource as a service with a standardized
interface
Enabling them to exchange structured information (messages, documents,
‘business objects’)
Mediating the message exchange through an Enterprise Service Bus
This flexibility enables new and existing applications to be easily and
quickly combined to address changing business needs.
The ability to easily combine/choreograph applications allows IT services to
more readily reflect business processes
The SOA infrastructure is also used to facilitate the management of
business performance and quality of service
